NAUI NTEC Doubles Primer

WHAT WILL YOU LEARN?

Our NAUI NTEC Doubles Primer Workshop is a Primer program that acts as an awakening of sorts introducing the Recreational Diver, preparing them for diving with the most beneficial doubles equipment configuration and foundational skills that all divers should have.

The NTEC Workshop is the perfect starting point for students to being their path towards more disciplined and polished diving skills and techniques offered as a crossover to our style of diving if coming from the more pedestrian Diver Courses offered by the majority of dive shops around the world.

NTEC is a mini workshop/experience program that outlines the benefits of diving with a more streamlined, simple, safe and comfortable doubles equipment configuration, setting up more skills oriented double tank dives and getting ready for the NAUI Intro to Tech Course, which is the most challenging course enroute to becoming a cave/technical diver.

NAUI NTEC is a hands on opportunity for divers to rig their gear properly under our supervision to start utilizing the most modern methods of skill in this configuration.

All foundational skills training starts off in the classroom and pool…

We are currently offering this program on a regular basis with the opportunity to add-on an open water diving component with your Instructor to prepare you for the next step, which is the NAUI Intro to Tech Course.

Diving is something that is always evolving, improving and changing through new technology, training and experiences.  The concepts we implement and the way we think of posture, trim and technique gets taken to a new level of excellence as the average recreational diver has typically not been taught anything about trim, posture, streamlining themselves in water, or simplifying the equipment configuration.

NTEC introduces divers to streamlining gear for example how to clean up your existing equipment configuration, re-routing hoses that are too long or too short, as well as providing the diver with knowledge as to why this gear needs to be reconfigured or streamlined.

With NTEC, we utilize the use of a longer primary regulator hose, which is given in an out of air emergency to the out of air diver, while retaining the alternate air source quickly and easily because its located on a necklace around your neck.  Through additional streamlining we start removing all the “danglies” off the divers equipment, thus creating a sleeker, more efficient diver profile.

The “Traditional” equipment configuration that is commonly used in diving has become dated and obsolete and needs revision, this is where the NAUI Recreational Equipment Configuration has truly become “Today’s Equipment Configuration” for divers of all skill level from Open Water to Technical, Extreme Exposure Trimix, DPV, and Cave Diver.  It really is a multi-purpose, uniformed way to dive.

Upon successful completion of this workshop, students will be free to enrol in our NAUI Intro to Tech Course.

TRAINING AGENCY:

NAUI TEC

ADDITIONAL DETAILS:

Workshop training starts at 10am Saturday morning heading to the pool in the afternoon and finishing round 7pm

This experience program outlines the benefits of diving with a more streamlined, simple, safe and comfortable equipment configuration.

The NAUI NTEC Experience Program is a hands on classroom and equipment rigging session that allows the diver the opportunity to rig their equipment under the direct supervision of our NAUI Tec Instructor, followed by a Pool Session where skills will be demonstrated and students will have an opportunity to preview and work on these rudimentary skills.

While at the pool, you’ll learn the benefits of proper diving techniques, fin techniques, improved knowledge on trim and buoyancy, while shedding massive amounts of excess weight, bulk and drag versus a traditional equipment setup.

Upon Successful completion of the pool session there is an opportunity to complete an open water diving opportunity with 2 foundational skills dives and mentorship to help you move towards the NAUI Intro to Tech Course and pass it successfully.

Cave Diving – My Journey Into Diving Caves

Cave Diving – My Journey Into Diving Caves
by
Matthew Mandziuk

A lot of people ask me about My Journey Into Cave Diving – How I Got Into Diving Caves, and the truth is that it wasn’t on purpose. It was once upon a time when I was in Mexico doing some instructor updates for TDI. I’ve been a Technical Diving Instructor with them for over 20 years and I was looking for a trainer that could teach me more than the people I had met or worked with here in North America were able to offer. 

The Internet was relatively new to me…well most of us 20 years ago, but I had found a few trainers who kept coming up on WebCrawler and whatever other search engines I used…I think AOL. What drew me to Mexico was that the Instructor was seemingly offering something different in concept. His emails were more detailed even though English wasn’t his first language and the pictures looked like the gear was a lot tidier than my setup, which in those days was a very old school New Jersey Wreck Diving configuration, so I took a chance, hopped on a plane and went to Mexico.

We reconfigured my gear, as I was fascinated by how much cleaner and more streamlined the setup we were training new students on was and I embraced it all 100%.

It was knowledge that made sense and it made the diving so much more functional. (See the example of how my gear may or may not have looked at one point further down the post).

The Seasickness Day

One day we were out in the ocean boat diving in 14′ waves, when I got thrown from the boat by with all my gear on. Here was as good of a spot as any to drop on the wall, so we decided to drop right were I did and we conducted a nice 300’ trimix dive. As we entered the decompression phase of the dive shallower, the surge was very strong and I started getting a little queasy. After the stops were clear, we got tossed back onto the boat by the waves and we powered back to shore, I crawled tanks and all up the sandy beach on all 4’s and and kissed that unmoving ground. I likely even told it I loved it.

When my face wasn’t green anymore my Trainer started thinking about other less windy options and one of the ideas that popped into his mind was to do a deep sink hole, something I’d never seen before. I was in.

An Inland Road Trip

I remember the site well, Cenote Angelita. We drove into the jungle and parked a car, walked down a dirt pathway through the jungle of beautiful big trees, and we happened upon what looked like a tropical oasis in paradise. There were some tree roots we could use to walk down to the water way a little more safety and you could see down quite a ways into the water as the sun was peaking high in the sky just before noon.

When discussing the dive plan, we were briefed on the site and I got to discuss the dive with the dives I was diving with.  

We walked our decompression cylinders down to the water and tied a line off a series of strangler fig tree roots to clip the tanks to so they didn’t slip off the ledge down to over 200’.

We put our suits and double tanks on and on the surface we conducted our s-drill and bubble checks, clipped our additional cylinders on and away we went.

I remember looking into the air clear water and I could see all the way down to the bottom at 90’ where there was a hydrogen sulphur cloud and a beautiful reddish coloured rock in spots around the basin.

We explored the sink which was very reminiscent of Yoda’s planet Dagobah with the steam on the surface unearthing the trees sticking through the cloud, except this was now happening underwater and was one of the most mind-blowing and interesting things I’d ever seen in my life.

After taking in my new favourite site above the cloud, we decided to go in through the cloud. As we descended through the hydrogen sulphur cloud, I could actually taste through my regulator a flavour of sulphuric “rotten egg” which is a flavour everyone talks about. As I descended, I came into the darkness 40’ deeper and into a night dive like environment environment. HID Lights were just starting to come onto the market and it was my first time seeing a Halcyon 18w HID light in action. the blue light was so amazing. I was still using a 2 section car battery pack powering a 50w Halogen lamp, so my beam was yellow.

As I took the time to take in this new environment, I noticed a lot of branches, roots, a massive hour glass shaped debris cone, just like I’d read about in the many books I’d read on the Yucatan Peninsula and the water was even clearer below the cloud that above, which we could easily see the entire length of the basin above and below over 300’ of clarity on this day.

We kept following the debris cone downward towards the bottom which I could see getting closer and closer and we stopped at a cavern entrance with a beautiful speleothem hanging and all of the divers lit up the entrance with their high tech HID lights and my halogen lamp.

I Was Mind Blown…

I was mind blown and the entire dive had eclipsed all of my best dives in quality, uniqueness, clarity of water, cool things to see. I’d gone from never diving a sink hole to never seeing spelotherms, to being thrown into a new world of let’s discover what else is out here and a trip that was only supposed to be 1-2 weeks lasted a month, as I so excitedly and enthusiastically ascended after our decompression ended and smiling ear to ear they asked how I liked that site!? My reply was that it was the best dive ever. They later replied, if you like that we have some even bigger and better treats for you “Farmer” (in response to being seasick and kissing the sand the day before).

We did a second dive at Angelita was just as good, but a bit shallower as we broke 200′ of depth on the first dive. We had even more time to swim around and play in and out of the hydrogen sulphur cloud. It was very memorable.

Upon feeling renewed and excited, we did a bunch of other fun dives in the area and all these big deep sink holes just made me more curious about what else was inside them.

One day I was asked to teach a decompression lecture for a bunch of cave students and was convinced to join on the open water skills dive on day 1 of these students working on their cavern skills. It was pitched to me that I could learn how to use a reel better and it would help make the best wreck diving class in the world.

The day we did the class, then we started working on dry land drills and having never actually been taught to run line and only reading from the old NSS-CDS and NACD cave books, I was excited to see how they did things, so I sat and watched and when the students were done, I too had a chance to play with the reels and line following and then I joined the group during the simulated air sharing while blindfolded and communicating during “touch contact” and I thoroughly enjoyed being blind and feeling the way the line in my hands moved left and right and up and down and how I could use the sense of touch to feel the plastic navigational markers as a way of knowing roughly where I was and what direction was out.

I was done all of my TDI Technical Instructor upgrades and lectures by this point and it was time to immerse myself into something new. Cavern Diver Training!

My first cavern training dive was in 20’ of open water at a cent called Car Wash. It was the most intense dive of my life because I was taking everything so seriously. We have a great Cave 2 Skills Video summary of some of the skills online if you’re interested CLICK HERE.

For those who know me, I’m a pretty OCD and very thorough person when it comes to diving. I’m hypersensitive to things and usually very very aware and I liked this because it was challenging me in a new and different way.

For those who have done a Wreck Penetration, Intro to Tech, Cavern or Cave class with me, I’m sure you’ll remember our 20-30’ dives too. The shallow skills development dives set the bar for things to come.

On my Cavern Training it was not different. We spent 1.5 hours in 20’ of water doing air shares with and without visibility, with and without a buddy, we simulated a lost guideline deploying a safety/backup reel and had to relocate the line, tie-off our safety line and follow the mainline until we found an arrow marking our exit and make an exit in the proper direction. 

DDS Divers Working on Line Handling and Awareness

Don’t Be Intimidated….

While many people find a dive like serious training dive to be intense or intimidating, it just made me want more. As a matter of fact, I took the next dives so seriously that it took me 20 minutes to even realize we were in a cavern because I was so focussed on the team, the communication, the line placements and etiquette, among the other pre-dive rituals we had ahead of the penetration into the cavern, that it felt more organized diving this way.

Once we tied into the main guideline I was able to break a sigh of relief that we found it and then I was able to stop and take it all in and this cavern became something that allowed my body and mind to slow down and take it all in as the stillness was enhanced, my breathing rate lower than the last 20 minutes had been and and I heard every heart beat, the sound of every breath flowing through my long hose towards my mouth and the lights all cascading a beautiful array of light patterns around this magical limestone paradise that were created millions of years ago.

As the divers began to signal the turn and exit and somehow one at a time had “equipment failures” with masks being removed, primary lights failing, people running out of gas, etc., I was watching and waiting for my time to exit and don’t really remember if/what the problems I would’ve encountered were, but again after sorting our gear back out when the scenarios were over, and our safety stop completed, we ascended into another monumental emotional diving bliss moment as we were all smiles and ready for the next challenges.

True Beauty…

The thing I loved most about the cave diving training were the beautiful caves we were training in. Seeing the ice-age looking formations that resemble the frozen icicles at a waterfall were hypnotic, as were the stalactites and full columns (once I was able to start enjoying them and paying less attention to the main guideline or the equipment that I knew was going to “fail” on the exit).

The skills that we had to do on the class were addictive and I even “died” on my lost line drill, which is a survival skill we do as we simulate losing the primary line and having to tie off our safety spool on a rock and blindly feeling for the primary line, hoping to hook it with our reel, or even our equipment or body. 

Skills that like were very sobering and they drove home the importance of paying attention to the team and surroundings at all times.

Learning to navigate a jump from one line to another cave line was another wonderful skill too, as it extended our range into these cave passages.

What I loved most about cave diving were the rules and how organized cave diving made me feel. I used to always say Wreck Divers used brawn and Cave Divers used brains. I’m a big advocate of diving smarter, not harder and Cave Diving was something that just made sense.

One of the most interesting aspects of the Mexican cave sites was the haloclines, a phenomena of waters of different density and temperature that can create a visual disturbance like mixing fresh water into a glass of saltwater resembling how a road shimmers in the hot summer heat.
Here you’ll notice the fresh water layer on top pushing, mixed water in the middle with the salt layer along the bottom.

Halocline Formation in a Mexican Cave During NAUI Cave 2 Class

A thermocline can get more brackish as your pass through the layer and it creates a greater mix of the salt and fresh water which can obscure view of the main guideline. Learning how to dive in Halocline Formation is important.

I learned some valuable lessons on the cave class as well and helped reconfigure my equipment, as I maybe had some “wreck diving” equipment, but not stuff gear that was as streamlined or as functional as the gear I ultimately embraced. Even a little think like the importance of a good pair of fins. I was an advocate of Mares Quattro’s for years, they were a fantastic pair of fins, but couldn’t figure out why I was having to kick to keep up with some of the other divers, given I was running 5 km’s/day, my friend Nick said to me straight up “it’s your fins. They’re too big, bulk and too inefficient”. I switched to Jet fins after I got to try them minutes later and never looked back.

Technical Diving at DDS Looked Reminiscent of this in the ’80’s and ’90’s. Lots of Gear and Task Loading with hoses ,tanks and gauges galore. Be Blessed You’re Learning the Right Way from Open Water On. This is Why Divers Come From All Over North America to Train with DDS.

The importance of the right equipment that suits the team’s mission and members best is very important and another favourite aspect of cave diving, as those team members can help with the line tension, retrieving arrows or cookies if asked, while having their gear rigged the same way in the same location always.

I remember on one of my first cave trips back to Mexico, I got to dive in one of my favourite Mexican cave, where we navigated through 3 different cave systems on 1 dive! Now of course each cave once it’s connected becomes part of the biggest cave system, but once upon a time they were 3 separate cave systems.

With proper dive planning, great gas consumption and the right safety gear, cave diving can be one of the most enjoyable and stimulating styles of diving ever.

Cave Diving is Not Dangerous. Breaking the rules, exceeding your level of training or experience is. The caves have been here for thousands and millions of years before divers started exploring them, they’re not the hazard, human error is.

In Cave Diving they use the expression “There are Old Cave Divers and There are Bold Cave Divers, but No Old Bold Cave Divers”. Having lost friends diving, it’s not fun, but at some point a rule was broken or a training limitation in the majority of the losses I’ve had to endure. Thinking of your friends and family first will act as insurance in wanting to return home safely, so that you don’t make unnecessary risks and you can keep your mind in the game.

Don’t Make Unnecessary Risks, it’s not worth it.

From Student to Teacher and Explorer


My cave training opened me up to a lot of amazing adventures, but the faster approach to the training was something I wasn’t as keen on. 

Many divers do a “zero to hero” cave class in certain places, it’s not to say it can’t be done, I did it, however, I was the only diver who knew how to frog kick, turn or fin backwards along with 2 students who’d done open water and advanced with the same instructor in a backplate/wing, but reverse frog wasn’t a required skill, nor was any previous experience in doubles and this is still the case in a lot of the more mainstream agencies.

I really felt like the other students could’ve benefited from a foundational skills class which really was just starting to become a thing 20 years ago. It was rare that divers would have learned the foundational skills and have proper horizontal trim. A Cave Instructor in Florida one day told me they are there to teach a student as much as they can in a week so they don’t die in a cave. Many have never worn doubles, been horizontal or frog kicked, so they do the best they can and they offer them the opportunity to re-take the course within 6-12 months of they practice and get the diving in, but what they really should do is teach them the foundational skills first and then focus on the cave skills/training next. On my cave class the others were new to all the gear and techniques and the open water dives we had done prior to the cavern dives were designed to try and teach them the basics of modern diving.

Cave diving was a lot more mental for me than physical, having to think of the procedures to lay a clothes pin (now we use cookies) or when to arrow and where, as I felt we were hit with a series of navigational decisions and there was a lot of additional gear thrown in like stages and so on.

Complex Navigation involves multiple navigational decisions, entering and exiting in different places, doing circuits, T’s, traverses, set-up and clean-up dives to execute the dive properly.

It wasn’t until I got out on my own exploring new caves, some known, some undiscovered cave sites that I started to gain or retain the knowledge and apply it. I had the skills, I could do the drills, but putting them to practical use was really what made me feel like a cave diver and made me a better diver.

Many divers are quite content just following the main guideline in and out, it’s enough for some people and definitely how you’d want to start off if you haven’t done a cave dive for a while. Ease yourself into the dives doing easy navigation or what I often call diving like a “pedestrian cave diver”, as the simple tour is a nice way to reacquaint yourself with the caves and running the reel and tying into the main guideline, you can assess the conditions and note the navigational jumps or places of interest for future dives.

When it came time for me to be teaching Cavern Diving, I had no interest in teaching Cave Diving. I had a few friends in Florida and Mexico who I’d send friends to dive with and train and that was good enough, but none of them really stuck with it and my local divers were getting more and more keen to go to see these amazing springs and cenotes.

All of the years I spent in Florida and Mexico started mounting up, I started seeing the masses who were cave diving and they were destroying the fragile stalactites in Mexico or breaking the limestone features of the Florida caves.  My favourite decoration in Ginnie Springs got destroyed last year I named it “Scooby Doo” Rock and one day someone decapitated Scooby likely with Doubles or a Run Away Scooter.

scooby-doo-rock

As more years went by, I started seeing people flutter kicking even in a no flow cave in Split Fins destroying the visibility, hand swimming and vertical diving habits, along with people pulling hard on the cave guidelines which should never be pulled or heaved on, and only held with caution letting the line slip effortlessly through your fist as you grip it in a touch contact hand position. Most divers didn’t know how to run line properly or at all, while some people were just running a single long line for 200’ into the caves and tying in to the main line with no regard for the other lines, divers, teams or anything.

During those days, it was our Divers loved ones who were telling me that they didn’t trust anyone random person to train their loved one’s and they insisted when their loved one was ready to step it to the next level that I’d be teaching them because if I was the only one they trusted 100%, which was flattering and I accepted eventually, which turned out to be a great move.

For the last 13 years I’ve enjoyed teaching caverns and caves, but finding a cave agency I could relate to and enjoy working with was a serious decision too. I teach for 5 different agencies, but what I wanted out of an agency was a brand that suggested divers get more diving in between each level, much like I had wished I’d done vs the “Zero to Hero” approach, so I looked at all the agency standards and all of the prerequisites that each agency insisted on and none of them were requiring experience in doubles, or a foundational skills series of skills such as fin kicks or horizontal trim, posture, buoyancy, which is why I looked at NAUI as my preferred Cave Diving agency. Seeing the NAUI Standards was a game changer for me.

NAUI allowed divers to dive a 1/3 of their gas in, out and exiting with 1/3 for reserve, while the majority were doing 1/6th in/out and 2/3 let for exit. No jumps off the mainline, or 1 at best. Being able to participate in multiple navigational decisions was also a great offering, as was the depth limit of 100’ max, no stop limits and insisting certified Cave 1 Divers had to log 20 logged Cave 1 dives after their certification above and beyond their cave training dives, obtain a technical certification before engaging in Cave 2.

There were gaps left in my basic cave training that I saw as a bit of a short coming with some of my dive buddies on my cave class not knowing how to fin using a modified frog kick, not having experience in doubles, trim, reel handling or line awareness prior to a NAUI Intro to Tech Class, no experience with stage/deco/ bottles prior to being handed them in a cavern/cave setting, lack of familiarity with canister lights and back-up lights, rescue diving scenarios dealing with oxygen toxicity and more.

Cave Diving has given our Canadian Divers another way to keep their skills sharp during the winter months and while most divers fade in and out of the recreational diving spectrum, I do find that those who commit to an Intro to Tech/Cavern course and actually pass, never stop diving, as Cave 1 and Cave 2 become their next classes and then as it’s been now 11 years later many of those Cave 1 and 2 divers are still joining us on our trips today.

Cave Diving offers some amazing exploration opportunities, some great personal challenges and some different opportunities for photography and other offerings too.

Avoid Rushing Through Basic Training and Into The “Trendy Toys”


There is never a substitute for experience.  Getting your skills in place and your hours up are the only true way to become a proficient diver.  It doesn’t happen easily or overnight.

Surround yourself with a group of Divers you can learn from.  We use a mentorship mentality that helps prepare new DDS Divers who aren’t trained in the DDS philosophies and we encourage our “home grown” Divers to stay as active as they can and to get involved as much as they can.

We are trend setters and people that were responsible for helping establish many of the protocols and procedures now taken as the bible of diving.

We innovated the most modern Sidemount Configuration before anyone started diving long hoses and embraced the most modern CCR Rebreather Configuration with back mounted diluent and off-board O2 before it was the norm.

A lot of divers jump into certain concepts because the wrong people are promoting the wrong progressions, maybe it’s because they themselves couldn’t dive the right gear for a physical reason like shoulder surgery or bad back, but nothing is better off a boat or driving a scooter than doubles.

Sidemount is a tool to get you into a place you can’t fit on singles or doubles or for shore diving. It is better suited after Cave 2 when the divers have extensive cave experience, the ability or desire to do tighter passages or “no mount” passages even. Sometimes caves are not accessible on doubles, so Sidemount is the Correct Tool Here.

There are many caves that are simply too tight to get into with doubles, so once you’re familiar with all the cave diving has to offer, Sidemount becomes another tool you can use for expeditions where you don’t know if the cave will widen or narrow further.

Sidemount is Not for Mixed Gas Diving and is a horrible choice when diving off a boat, especially if people are diving an unrefined Sidemount configuration which is typically what we see locally from most shops/instructors/divers who are not cave divers.

Sidemount is amazing in places where doubles aren’t available for rent, because you can maintain the redundancy.  Sometimes on shipwrecks or in caves, doubles don’t fit, so Sidemount is the tool of choice as well as for those who medically can’t reach their valves due to spinal or shoulder injuries (having an ill-fitting drysuit/undergarment are no excuse).

Rebreathers with small little 2-3 litre cylinders are also an issue we have. Most Cave Divers Do Not Carry Enough Bailout Gas. A Cave Level 1 Dive = 140ft3 bailout minimum. A Cave Level 2 Dive = 225ft3 bailout Minimum. This means said Cave Diver Needs to be excellent with multiple Decompression Cylinders. In NAUI Cave 2 Divers Learn to use 3-4 additional bottles plus doubles.

Get Good on Stages and Doubles Before Venturing into Sidemount or Rebreather. Once you’re proficient in those styles of diving You can do DPV Overhead/Cave Course which may be safer on a CCR for gas time and efficiency as you’re travelling further back in the cave, but you should always swim it first on Open Circuit First and See how many cylinders it takes for if/when the DPV fails and you may swim on out of it for real.

Taking the right training, buying the right gear, putting in the right amount of time practicing is essential for any divers success. Don’t Rush into caves, technical diving, rebreathers, sidemount diving.  Don’t Take Shortcuts in Your Training.

There are so many amazing dives sites at every depth level and ever training level you succeed at. There is always a next deepest, and next best as well.

Don’t even attempt to dive a Rebreather in a Cave unless you can hover motionless for 5 minutes no skulling horizontally, Knees Up, Fins Up, Arms Out in Trim and complete all the Foundational Skills with 2 Stage Bottles On. I say this because several people have been unsuccessful in Intro to Tech with us and jumped into a Rebreather and somehow got Normoxic Trimix certified standing and kneeling on the bottom, ascending holding the anchor mooring lines and flutter kicking silting out the ships just like their Instructors do.

Your Best Option for a Rebreather is Manual not electronic, so you’re in charge of your PO2 and can control your ascents easier without the set point screaming at your as the PO2 reduces on an automatic unit as it goes shallower while still trying to achieve it’s constant PO2. Run it at a .6 PO2 on ascent or manually. On Deep Cave Exploration a constant mass flow valve or needle valve modified from the original KISS Rebreather design is another great option.

Cave Diving is for Divers Who Have Elite Skills and Discipline and a Desire to be the Most Polished Divers They Can Be.

Spending a lot of time in Florida, Dominican, Mexico and enjoying the recreational and exploration aspects of cave diving have been very fulfilling. I throughly enjoy expedition style diving, having been featured in magazines, YouTube videos, agency and personal expedition projects, including helping friends map the largest cave system in the world, just a couple of years ago, in a land so far away from this Covid pandemic are what keep me motivated and keep me going forward.

If Cave Diving Interests You, Do it Right. Take a Foundational Skills Class with DDS. If you’re curious about doubles, take a NAUI NTEC Doubles Workshop with Us, which will start you down the right path in equipment configuration basic foundational skills, while our NAUI Intro to Tech Course is the best Foundational Skills Class there is. It offers the right skills, information and adventure. Intro to Tech dovetails seamlessly into Cavern/Cave 1 too, so do it right and take the best training path. Don’t leave gaps in your training. Don’t Rush and Never Accept a Certification Card You Yourself Do Not Feel You Earned.

Our Cave, Wreck, Overhead and Technical Diving Courses are The Best in the industry! No other training agency offers a more through and complete Cave Diving Education and having such a small number of Cave Instructors keeps the quality high and the demand high.

Going from a Left Post Breathing Hose Stuffer to one of the First DIR Based Diving Instructors was the best move we made as a shop. Divers come for the best training offerings from around the Canada, the USA and other countries. I’ve been a Top Certifying Technical Diving Instructor over the last 20+ years and with your help will continue to offer the Highest Calibre of Recreational, Cave, Technical, Sidemount and Rebreather Training Possible.

Seeing the benefits of Divers learning in backplate/wing from open water, encouraging continuity in gear configuration, improving team diving communication and functionality and being able to up the game whenever possible are just some of the ways we’ve helped set the standard higher.

I am frequently involved in cave and shipwreck and other random dive expeditions of known and unknown entities and we continue to challenge myself and others through new environments and equipment whenever possible.

Diving Dry with Doubles

Diving Dry with Doubles
by
Matthew Mandziuk

Diving Dry with Doubles.  Have you ever noticed that the most active divers on the dive site are the one’s who are Diving  Drysuit with Doubles?  Quite often its the same 10-12 divers who sign up for a lot of the same trips and who often prefer diving together with the group.  The reason for that is comfort, with their kit, with the group, with themselves in the water, whereas the other 10-12 guests are a revolving door of divers with a ranged diving background.

In this blog we are going to talk a little about the benefits of diving Diving a Drysuit with Double Tanks.

By the end of this reading you should have a clearer understanding of the partnership between diving with a drysuit and doubles, the benefits of diving with a drysuit and doubles, some of the training offerings with divers in a drysuit and doubles and where diving in a drysuit and doubles can take you.

Why should you start Diving Dry with Doubles? 

At first it sounds a little much, diving a nylon or neoprene full body suit, hood, gloves and then more weight than we even used in a wetsuit?  Drysuit divers wear approximately 6-8lbs minimum in fresh water (more in salt because of the added buoyancy)  more weight than a diver in a single piece 7mm jumpsuit (or about the same weight as they’d wear with an old school farmer John and Jacket).

That added weight can be inconvenient at best.

Where does one put that extra weight?

Most of our DDS Divers utilize a backplate and harness system which promotes better horizontal trim, posture and streamlining , it’s expandable and fully adjustable to accommodate the drysuit much easier than a jacket bcd can and is far more comfortable.

To learn more about backplates in general, please click the hyperlink above.

Divers diving in Canada with a single tank often times use a stainless steel backplate with a weighted single tank adapter, that system has a total negative buoyancy weighting of approximately 10lbs.  Nearly enough to sink anyone in a 7mm wetsuit with 2-3lbs maximum per side additional, however a drysuit diver is going to require an additional 6-8lbs minimum depending on the undergarments they wear.

In an attempt to  promote proper horizontal trim, the diver will want to re-distribute the weight evenly around the body with a maximum of 4-5lbs per hip pocket and up to that much weight on each of the single tank straps for a total of up to approximately 20lbs of weight plus the backplate system = 30lbs. Doesn’t that seem like a little much?

In an attempt to minimize the weight the diver wears, many will go to a single steel tank which can be 2-8lbs negatively buoyant by todays standards diving with a Faber steel cylinder.

A few years ago Worthington cylinders were preferred for their additional negative buoyancy characteristics with the X7-100 and X8-130 being the 2 most popular options.  In Faber the FX100, FX133 and LP85 are our most popular sizes.  Strangely enough the 100’s and 130’s were also the most suitable tanks for doubling up for deeper dives.

Faber FX100 swings from -8.41lbs full to -0.59lbs empty.
Faber FX133 swings from -9.08 full to +1.45lbs empty
Faber DVB85 swings from -3.8 full to + 2.32 empty

Worthington X7-100 had a swing of -10lbs to -2.5lbs
Worthington X8-130 had a swing of -11.7 to -2lbs

Having a tank that is negatively buoyant allows divers to reduce overall weight required and keeps some of that negative buoyancy behind you which helps improve your trim rather than having all that weight on the hips, but you don’t want to overweight yourself with tanks too heavy and underwear too thin.  Try and find the balance.  Many divers will even favour aluminum tanks for shallow shore diving with thin garments.

Adding an extra tank minimizes or eliminates the need for additional weight while adding a safer configuration that builds on our progressive single tank system utilizing a long hose/short hose and spg on 24″-26″ HP hose and it gives divers  the ability to solve a catastrophic failure thanks to redundant regulators.

Aluminum twins are popular option for divers looking for a great wetsuit set that can be used with a drysuit, however, they are more suitable for use on shallow dives.  When worn with a drysuit the diver will have to wear a heavier steel plate, a v-weight with lead down the centre of the tanks and a compact and streamlined wing.  They are easy to dive with little learning curve.

Steel tanks will take the diver further through deeper dives, caves, wreck penetration and offer more reserve gas on the divers back to deal with emergencies.

Many divers prefer the additional gas capacity of the steel tanks as well as the larger sized tanks allow divers to dive deeper and stay longer in comparison to the standard aluminum 80 tank which is still the most popular scuba diving tank on the market.

 

Drysuit Divers and DDS Divers have better trim because a drysuit surrounds the entire body with a little bit of air (less is better).

Redistribute weight, minimize weight and enjoy easier diving.

 

As divers tend to dive more off the dive boats and spend more time on their favourite dive sites, divers start looking at how to get more bottom time.

Diving Nitrox allows divers to gain up to 50% more bottom time on sites around 100′ and deeper, while yielding even more bottom time shallower, however, the limiting factor at that point tends to be their breathing rates and the sizes of tank they use, so a steel tank will in fact increase their bottom time an allow them to achieve their dive plans up to the Nitrox NDL most dives.

For divers who find even on Nitrox, the NDL isn’t always long enough, extending their range into decompression diving often is the trick, as a diver learns how to properly and safely plan their dives with a little bit of decompression utilizing advanced nitrox mixes to accelerate decompression times.  This is where doubles are most beneficial.

DDS Divers practicing bottle handling

When a diver combines the drysuit for maximum exposure protection and comfort along with a set of twin tanks, they no longer have to worry about switching out their tanks on that rocking dive boat in between dives, they no longer have to worry about adding weight to their hips or anywhere usually on their body, and they can certainly benefit from the increased balance and comfort that doubles offer.

You’ll also find divers enjoy just going out and working on foundational skills is easy to observe as our divers are always out in open water honing their skills.

Diving Dry with Doubles allows for more even balance in the water as the tanks are placed over top of each lung rater than down the spine like a single tank, while giving the diver a more comfortable suit to don and doff.

Drysuits are easier to put on than a 5-7mm wetsuit.

Drysuits are more effective for warmth retention.

Crushed neoprene or trilaminate Drysuits don’t compress with depth like wetsuits which get thinner with each atmosphere making the diver heavier because of the initial weight they start the dive with, as well as making the diver colder because those thick suits become much thinner every 30ft/10meters they descend.

Are Doubles For You?

If you can carry them on your back, reach your valves and dive with them comfortably, the answer is yes!

 

Look at the number of  accidents that have happened in recreational diving situations with single tanks, especially on deeper dives.  Most recreational diving accidents occur in a single tank with no redundancy (pony bottle, sidemount, h-valve, doubles) or lack of training.

A diver breaths their tank empty, their buddy runs out of air and they didn’t reserve enough gas for them and their buddy to ascend, they went in cold water and the regulator froze up, they hit the regulator or tank valve off a shipwreck or overhead environment creating a catastrophic failure, the BCD freezes, their dive computer blows off the end of their high pressure hose (another reason to wrist mount your computer) so they panic seeing bubbles streaming out of the high pressure hose, etc….

Minimize the risk, Increase the Fun and Learning and be more mentally and physically prepared with more advanced training.

If you’re interested in diving deeper than 80′, cavern or cave diving, technical diving, ice diving, mixed gas diving or wreck penetration, you should do it on doubles.  To many people did it wrong and it cost them their lives.

Be the best diver you can be.  Get involved with DDS and we’ll make you the best diver you can be with our training, experience dives, trips, charters and exploration offerings.

We’ve found these factors to be some of the most beneficial tools to extend your diving into a more fun and exciting world:

Dive Planning: Plan Your Dive, Follow Your Plan, Have an overplan, bailout plan, but don’t deviate from the main dive plan

Gas Management: 1/3 down and around, 1/3 back, exiting water with 1/3 of your gas supply 

Redundancy: Doubles allow the ability to shut down your regulator in the event of a failure, free flow, freeze-up, burst disc failure etc. Isolation manifold allows to shut down and switch over by isolating and shutting down the offending post or just shutting down the offending post.

Narcosis Management: Don’t Dive Deep On Air.  You’re narc’d at 130ft/40meters whether you know it or not.  Don’t dive deep on air, it’s silly, outdated and unsafe with education and helium training available now.

Team Diving: Serious Diving requires divers you can trust in an emergency and in an pinch. Don’t just dive with the randoms you find on a boat down south, they’re usually once a year divers with horrible habits and inferior training.  Dive with divers you have a positive history with or as ask us and we can refer you to more progressively minded shops

No Solo Diving on Deep Dives: Solo Diving is popular now, we’d likely choose this option if diving south with random divers instead of having to buddy up with people that we don’t feel comfortable diving with, however, deeper dives require piece of mind, extra equipment and a proper plan with lots of “what-if’s” to be safe guarded against.  It’s not worth solo cave, solo deep (exceeding NDL) or solo overhead environment without buddies

Analyze Your Mixes: Always, Always, Always analyze your mixes when you pick your tanks up, make sure they’re labelled and if diving with a fill that was “just filled” and you have to grab and go, analyze it again before your day of diving begins.

Practice , Practice, Practice: Complacency Kills.  Work on trim, buoyancy, bottle handling, dealing with simulated emergencies, smb deployment, alternate fin kicks, etc.  Be the most polished and best diver you can be.

Fit is Everything

Don’t just jump into drysuits and doubles blindly.  It requires the right fitting suit and undergarments first and foremost.  Many brands of drysuits are inferior in fit and quality, even the brands offering “custom fit”.

You’ll notice most shops try and pedal the cheaper suits that are like garbage bags or garbage bags wrapped in lycra to cover up the garbage bag look. This is like buying a drysuit from McDonald’s!  Don’t Waste Your Money

If you truly want to LOVE your drysuit and want to enjoy using it, take the time to get properly measured and properly fit.  Don’t just let the dive store hand you a suit off the rack and tell you that it’ll fit you perfectly, we’ve had that happen to several students from out of town that couldn’t complete their required skills during Intro to Tech Training and ended up renting suits from us to finish the class, then ultimately buy a brand new suit from us.

Do it Right.

We are partial to Diving Unlimited International because they offer the best quality, service, workmanship and there is an actual after sales service with them.  They are our top choice for hard to fit people too.  It’s all about comfort and fit with them.

DUI have great value priced suits with their Coronado, San Diego and Yukon II suits and the new Cortez (2019) suits obliterate most brands “top of the line suit” for quality, features, performance, as well as coming with user replaceable quick change ZipSeals, meaning you don’t have to send the suits away for service unless you damage the suit or zipper!  No brand can compete with that!

Santi offers a great quality and great looking suit.  We do their stock and modified stock suits.  You’re allowed up to 4 alterations at no extra cost with them and they do offer custom too.  Suits are very tough and stylish with a beautiful Euro look of elegance and colour.  They do take some time 2-3 months typically (sometimes less sometimes more).

Fourth Element offers the most flexible drysuit on the market.  It’s durable and looks great and they’re using technology to their advantage instead of dive stores who can miss measure someone by using BIOMAP technology to digitally create an image of the person to cut the suit for.  Great suits for a great price with great service…it might just take a bit more time to get the suits made 2-3 months typically.

BARE offers a great stock suit at a good price depending on what you get with the suit from your LDS.  Just but it from DDS and you’ll be happiest.

The Drysuit Underwear is as important for fit and mobility as the drysuit itself.  Santi offers modified stock and custom underwear, DUI offers DuoTherm ultra stretch polartec suits for custom fit as well as a great selection of stock sizes in up to an XM450 material which is exceptional underwear for cold water.  Fourth Element offers an amazing range of suits for a range of conditions made with some of the nicest feeling and fitting materials.

NTEC and Intro are the 2 most exciting, modern, challenging classes that will help improve your skills and enjoyment in the drysuit the most. Tie in NTEC and your PADI Drysuit Specialty Course together and see diving with a  different mindset than what you’d hear/see/learn in a traditional PADI system of diving education.

Diving Dry allows for longer bottom time in cooler water or more dives per day. A more comfortable gear up experience from a boat.

When you look at our DDS dive trip pics on Facebook or Instagram you’ll notice aside from a pool or an open water course weekend, the majority of the divers you see on our trips and con-ed classes are all in drysuits and you’ll notice that a lot of the same divers come out year after year on our charters and trips because their level of enjoyment is substantially higher than a wetsuit divers.

A friend of ours had a shop in Massachusetts and they trained their divers exclusively in drysuits.  They offered by far the most expensive open water course from NY-Maine and everywhere in between, yet their continuing education rates were 400% vs a national industry average of about 25% of divers who go diving and train after open waters.

So they found enormous success training their divers and promoting colder water diving trips because like DDS, they realized the best diving in the world was around the Great Lakes, Atlantic wrecks, Florida and surrounding areas. They were right.

In Closing

Drysuits will last you longer than a wetsuit, will give a diver buoyancy control that is easier to maintain when you where a little “squeeze” on the suit vs a wetsuit which compresses and changes depth the deeper or shallower you go.

Drysuits will allow for colder water immersion and more dives per day, while in between dives the divers will warm up faster, so the energy that is rejuvenated is much higher, especially with todays’ warmer Thinsulate’s and heated systems.

Combining a drysuit with a set of doubles sets a diver up for a lifetime hobby where anything is achievable.

The divers can spend more time under the water enjoying their hobby.  They don’t have to change tanks awkwardly on the boat in between dives like single tank divers do.  They add a larger gas source to deal with emergencies such as low on air or an equipment failure, while also adding redundancy in the event of a regulator or valve failure.

Aside from a little extra weight on land, there isn’t much difference between a single tank and a lot of lead to sink a recreational diver and a set of doubles.

For divers who can’t wear a set of doubles, try Sidemount!  Sidemount is a great option for divers who don’t have the ability to reach back to shut a valve down or who have had back surgery or a physical limitation that negates the ability the wear doubles on their back.

At Dan’s we believe in a more fun progression, so training our divers the right way from the very beginning is so imperative and gives them so many more options moving forward beyond Open Water, Advanced, Drysuit, Rescue, Divemaster and Instructor.  Don’t get caught in the boring progressions that the recreational agencies endorse, there is a much more fun, challenging and enjoyable progression ahead.

Experience more in the world of scuba diving instruction with Dan’s and let us show you a better way to do things that makes more sense and creates better divers.

Dan’s is an innovator of progressive recreational and technical diving, bringing the most modern skills and philosophies forwards before anyone in Canada as we continue to lead and offer the highest standards and most exceptional dive training for recreational and technical diving and have helped shaped some of the finest explorers in the world of scuba diving too.  Train with Dan’s and see a brighter diving future.

Diving a Backplate The Best Option for New Recreational Divers – They Don’t Tip You Facedown

Diving a Backplate The Best Option for New Recreational Divers – They Don’t Tip You Facedown
by
Matthew Mandziuk

There is a common misconception in the world of scuba diving that backplates  and wings can push a diver facedown on the surface.  Those people are wrong. Diving a Backplate is the Best Option for New Recreational Divers and unlike the majority of brands with front loaded weight pockets, most recreational jackets with back buoyancy WILL tip you face forward, a backplate will not.

In this blog we will outline with real life experience and even some fun video evidence how a properly setup and weighted backplate does not push you facedown, but in actuality it is the most comfortable, efficient,  streamlined and safest buoyancy system available.

Misconceptions

Halcyon_infinity_bcd_for_sale_online_dans_dive_shop
Backplates keep things simple and streamlined above and below the water.

The false mindset that backplates tip you forward on the surface  has ultimately come from divers who were using an improperly balanced back floatation bc with a horseshoe wing shaped bladder that was wider/thicker on the bottom of the wing and narrower/thinner in shape closer to the top. Other causes could be that there are high capacity integrated weight pockets located horizontally across the waist area of the bcd causing the force of gravity to shift.  This is why we opt for a vertical pocket that sits back towards the hip area. Or they just plain have never tried it.

A back floatation bcd with an improperly shaped wing design as described above coupled with front loading weight pockets that put the weight pocket closer to the front of the body laying the pockets from the middle of the body to front of the body rather than how they should be oriented, which is from the back of the hip moving from the middle of the body to the back of the body towards the backplate can create a very troublesome scenario with respect to body orientation and tipping.  As a matter of fact, some jacket bcd’s will even push you facedown.

Halcyon Active Control Ballast positions weight from the hips backwards towards the plate, which helps sit the diver vertical on the surface

A backplate doesn’t generally have this problem because it is a more balanced rig offering a wing that generally allows for even air distribution around the bladder like a circle or a doughnut that allows the air to move unrestricted and doesn’t trap air. Some units even offer a weighted single tank adapter with up to 6lbs/2.2kg of lead placed inside the STA with little to no weight needed with even the thickest wetsuit in salt water.

Divers may experience a tipping sensation on the surface from any bcd due to the action of over inflating the wing or a jacket bcd, however on a backplate and wing style system like a Halcyon Infinity MC System you don’t generally have this issue as shown in the video below.

Ideally You’ll want to get to a point where you aren’t wearing much/any weight with a wetsuit and have a balanced enough setup that you can simply just swim your gear up without having to kick hard to get there.  The more weight you have on the surface, could pull you facedown if the weight pockets are in the front of your harness and the wing is overinflated.

Explore shipwrecks with the right gear and comfort
Your Backplate can grow with you from singles to doubles, wet to drysuit, recreational or technical and rebreather diving. 1 bcd for everything.

If you’re using a drysuit you may need a little more weight, but a steel tank is also a suitable option or a set of doubles.  They balance you out even better and for diving locally offer redundancy in the event of a regulator failure.

How do you tell you’re overweighted?  Go up to 10 feet/3 meters with a 1000psi in your tank and see how much air is in your wing.  If you reach back and can feel a substantial amount air try venting the air out while laying horizontally and lifting your rear up, orienting your head slightly downwards to get the air to the highest point and use the back dump to vent the gas.  If you start going down quickly you’re overweighted, but this is another conversation to discuss in another blog post.  You should basically have no air in the wing and be able to hold a stop at 1000psi in an aluminum 80 at 10-15′.

The Unsung Hero

Backplates are the most streamlined, balanced, and versatile diving system for recreational divers, cave divers, technical divers and rebreather divers, offering you ONE uniformed diving system that grows with you throughout your diving career, making it the best option for a new scuba diver who doesn’t know where their diving will take them because they won’t outgrow their unit.  It can be dived with any exposure or tank configuration, in any environment, while offering the most streamlined swimming profile and neat and tidy equipment configuration when rigged properly for modern and progressive scuba diving activities.

Backplates allow for better buoyancy distribution and promote body position
Backplates allow for better buoyancy distribution and promote body position

A backplate can allow you to minimize bulk and clutter if you keep the harness clean, also streamlining your body if you are utilizing proper trim and posture, which should allow for you as a  scuba diver to maintain horizontal orientation in the water when swimming and when just sitting there hovering horizontally, even on ascent and descent, rather than being pushed or pulled vertical, which is the position a jacket or a bcd with the weights in the front of the harness generally do by pulling your body knees and fins down towards the bottom.

Backplates allow for motionless hovering keeping the diver within 10% midline of horizontal underwater but allowing you to lay perfectly flat and comfortable with head out of the water on the surface.

Simple and Streamlined

Backplates are more robust than a more traditional bcd, which are often ladened with excessive fabric, padding, straps, d-rings and breakable plastic buckles, whereas a Backplate simply has 1 release buckle if rigged properly, which is located just off to the right side of the waist and is right handed release like a weight belt buckle uses.

Backplates and Wings are available in all different shapes and sizes including regular, short and even tall plate lengths
Backplates and Wings are available in all different shapes and sizes including regular, short and even tall plate lengths

Clips and Buckles on a jacket bcd can increase task loading and may prolong rescuer response in comparison to a  backplate, as you’ve got a minimum at least 3-4 clips and a cummerbund to free the diver from their gear in a jacket compared to a simple right hand release buckle on the waist followed by pushing the harness free of the divers body.

Since more clips create a delay in freeing the diver in an emergency divers may want to avoid a jacket style bcd with fancy clips, gadgets and clutter in favour of diving more simple and streamlined.

Some backplates offer adjustable cinch harnesses to allow for easier donning and doffing, while not compromising the structural integrity of the harness with breakable plastic clips. To operate the cinch you simply pull the waist straps to tighten shoulders or lift the shoulders up to loosen the harness. There is no sternum strap to compress your chest and inhibit breathing, so you aren’t starved for air on the surface, the backplate thanks to a crotch strap and a proper fit prevents the bcd from riding up on the surface, and there is no chance that the backplate can crush your stomach and ribs like a jacket bcd with a wraparound aircell can when fully inflated.

Progressive Dive Training

Many of our divers are mindblown when they begin their journey into scuba diving and they see the poor job that the vast majority of dive stores and instructors are doing with scuba diving certifications.

Training with a more progressive dive store is a great way to get solid diver training, however, they are few and far between.

10309646_10156720498530512_7638916031124415553_n
Good Trim, Knees Up, Fins away from the reef. This is a great example of Progressive Diving.

At the time of this article Dan’s Dive Shop is the first and only dive store in Canada to be offering entry level training in a backplate system and a long hose/short hose regulator configuration at the Open Water Diver level.

Buoyancy and Trim and the most important skills a diver will learn and as such, those skills, along with air sharing, proper horizontal ascents and horizontal descents are things that need to be perfected.

Perfect Example of what not to do.
Perfect Example of what not to do.

Progressive Diving means to have the right skills, abilities, diver and team awareness, safe diving practices and understanding that they need to maintain their skills through practice and repetition on a regular basis.

In some circles this philosophy is known as Hogarthian, DIR, Doing it Right, NTEC and more. In all cases these methods have made diving safer, better and more enjoyable.

Buy it Once

If someone told you you could have 1 BCD to take you from singles to doubles, wet to dry, down south dives and on warm reefs and walls to the most beautiful cold water shipwrecks, cold water reef and walls or ice diving, would you listen?

Take a look on Kijiji or any of those used gear websites and you’ll see something that often states Jacket Bcd used only 6 times or 12 times.  When you talk to the owners a lot of the time you find out they upgraded to a backplate, or they bought a drysuit or a 7mm wetsuit and their original jacket doesn’t fit.

Not only is a backplate the most stable diving system, but it is also built to be the first and last bcd you ever need.

The Proof is in the Pudding

If you have been told that backplates tip you face down please take the time to share this video with the source of this misinformation.  Not all back flotation bcd’s are innocent, some will push you facedown, but a properly shaped wing and proper weight distribution and pocket design will not.
