Technical Diving Courses

Technical Diving Courses & Cave Diving Courses Overview

Dan’s has been involved with technical diving  since 1986 when we helped introduce Dive Rite to the Canadian dive market selling advanced gear and learning about higher level diving.   Technical Diving Courses were in their infancy, with only cave diving courses being available from a small group of Florida divers, but usher in the early 1990’s where we became the first Canadian certified Nitrox divers and one of the first Nitrox blending and training facilities through IANTD and TDI.

Since 1996 our technical diving course graduates have graced the water with more finesse, ability and experience than the vast majority of Technical Divers worldwide regardless of agency or instructor.  Our Divers are the most well rounded divers you’ll find above and below the water, possessing higher skill and abilities, a great sense of team diving values, pride, compassion and a willingness to help mentor newer divers.

What will you learn?

Our NAUI NTEC Program is an awakening of sorts that introduces the recreational diver to more of the foundational essential skills that all modern divers should utilize.  NTEC is a mini workshop/experience program that outlines the benefits of diving with a more streamlined, simple, safe and comfortable equipment configuration.

It is a hands on opportunity for recreational divers to rig their gear using the most modern method of diving equipment configuration. We are currently offering NTEC 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.

Our Style of Diving

The “Traditional” equipment configuration that is commonly used in diving has become dated and obsolete and needs revision, this is where the NAUI Technical 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.

Who should take this course?

NAUI NTEC (NAUI TECHNICAL EQUIPMENT CONFIGURATION) is A Modern Equipment Configuration and Introductory Course for the diver who wants the benefit of utilizing today’s most modern equipment configuration in a single tank configuration or a double tank system with an eye on the NAUI Intro to Technical Diving Course as their next step in the learning progression.

We offer a great mentorship that allows you to gain the skills and experience prior to enrolling in the NAUI Intro to Tech Course, which is one of the most challenging and rewarding classes a diver will take.

Everyone should take this mini course.

Prerequisites:

Discover Rebreathers DDS or as part of a Discover RB, RB1 or RB2 class

Basic Nitrox is the starting point for any rebreather training, however, we do not feel that is enough. We suggest all rebreather candidates have completed Intro to Tech and we recommend you have completed at least a Tech 1, Cave 2 or Trimix 1 course and are proficient with all of your skills, especially bottle handling at this level before moving on.

Rebreathers require more awareness, you have to multi-task, be aware of your surroundings, your breathing, your depth as your buoyancy is different on RB than on OC, so the more experience you have as a diver, the more it should help mentally prepare you for rebreather diving.

Our rebreather courses focus on modern technology, the right configuration (matching you up with double 50’s with a dual isolation manifold and a long hose/short hose/spg sort of configuration reminiscent of doubles, or you can do it dil and o2 if you want to dive old school).

One of the biggest advantages to training with us is you don’t need to buy your own

Tear down and cleanup after a day of diving

Rebreather!

Look at all the divers who buy one, hate it, are forced to use it out of pride and obligation and it ends up not being the best choice for them.

At DDS our Rebreather training allows you to rent your unit and see how much easier our preferred rebreather is to dive, trim out, breath from and expand it out for more advanced diving endeavours. Ultimately the choice is yours, but we recommend doing it right the first time.

What will you learn?

Our Tech 1 course package covers the Decompression Procedures course topics as well the Helitrox course as one overall learning package where you’ll examine the theory, methods, and procedures for planning staged decompression dives utilizing hyperoxic helium based mixes as  your bottom gas breathing mixture, as well as the effects of isobaric counter diffusion.

Through our classroom and watermanship teachings, you’ll learn what technical diving is, advanced decompression theory, dive planning, gas management, decompression gas planning, as well as tracking both CNS and Pulmonary Oxygen toxicity.

You’ll learn how to follow a decompression schedule, handle emergencies, contingencies, plan for over staying your dive plan and ensuring you have enough gas to safely get yourself back up to the surface.

Decompression is a course requiring sound thinking and judgement. Decompression divers cannot simply ascend when they have a problem.  All issues must be solved underwater, especially with a decompression ceiling above you.

Our Technical Diver Level 1 Program offers you the most advanced and modern training progression in technical diving today giving you more diving, more depth, more helium, no narcosis.

Instead of having to take each of the technical diving courses individually as stand alone programs, we packaged up 3 revolutionary technical diving programs to take you deeper into technical diving without the stress and added costs of taking each course seperately.

Technical Diver Level 1 allows you to build on what you learned in your Intro to tech training, builds on higher skill requirements and introduces you to diving with decompression cylinders, helium based mixes, advanced dive planning, theory and execution.

You will gain a vast wealth of information, you will be challenged by this rigorous program experiencing virtually every element of what technical diving has to offer.

Through the use of Helitrox (hyperoxic combinations of oxygen and helium), you will be able to safely dive up to 170′ extending your depth, while keeping your narcotic level comfortable, compared to dives on air or nitrox. You will accelerate your decompression through the use of Enriched Air Nitrox Mixes or pure Oxygen containing 100% O2..

Divers will complete a minimum of 10 dives for Certification and will be ready for real world technical diving environments upon certification.

Cost: $1200+ GST includes Student Training CD and Certification Cards (2) upon successfull completion of Technical Decompression & Helitrox, Technical Diver Student workbook, RGBM Tables Booklet, NAUI Technical Diver Student Text Book or will cover TDI eLearn classroom sessions.

Additional Details:

All too often in diving people think they don’t need training in specialized areas such as wreck, cave or overhead environment diving. These people don’t always live. The need for proper training in these specialized areas gives divers mandatory skill sets that aren’t often covered in other training courses, technical or otherwise, as the other courses are designed to introduce a variety of skills needed to improve the diver in open water. Even the most experienced technical diver should take this course.

There are inherent hazards and risks associated with exploring an underwater wreck, inside a sunken vessel, aircraft or similar structure. The only way to safely engage in overhead environment diving is to obtain proper training where under the supervision of an instructor you will experience a series of scenarios that could likely happen in this specialized environment. There are many valuable bits of information, skill sets and drills that will improve your chances of survival in a wreck diving environment.

You’ll learn about safety, hazards and special risks of overhead environments; gas management, entanglement, limited visibility, deep diving, equipment, sources of information, search methods, underwater navigation, legal aspects, artifacts, treasure, salvage, archaeology and appropriate material from other specialty courses as well.

The best part of this course is the hands on open water training sessions where students will learn how to execute a lost line drill, engage in air sharing while following lines, blacked out mask drills, lift bag deployments, anti-silting techniques, bail out situations, emergency procedures and much more! If you have NAUI Advanced Scuba Diver and NAUI Wreck Diver (External Survey) certifications or the equivalent and are at least 18 than you are ready to enroll in this amazing program, however, NAUI Intro to Tech is a course we mandate and recommend you take as a pre-requisite or in addition to this one.

Our Trimix Diver Course is for technical divers wishing to dive to a deeper depth taking advantage of the benefits of a true Trimix dilluting the partial pressure of Nitrogen (reducing Narcosis) and in deeper diving dilluting the PPO2 to avoid CNS O2 Toxicity.

This course covers topics such as Helium, Oxygen, Nitrogen for breathing gasses. Argon, CO2, Carbon Monoxide, advanced physiogy, physics and chemistry of diving (kinetic energy, specific heat capacity, tissue solubility and more), dive planning, table model comparisons, Isobaric Counterdiffusion and variations of trimixes are just a few of the many topics to be discussed. To enroll in either Trimix course, you must be certified as a diver with Advanced Nitrox, Decompression Techniques, Helitrox, Heliair.

The Trimix Diver Course consists of two levels. These courses will give you the skills and knowledge needed to minimize the risks of utilizing helium-based Trimix breathing gas mixes for dives to a maximum depth of 240′ requiring staged decompression and utilizing EANx mixtures and/or oxygen during decompression at Trimix 1 and up to 330′ for Trimix 2.

These Team driven programs offer some of the most challenging skills found in technical diving and test the diver more than any previous course to date in the students technical diving path. Upon Successful Completion of the course you will be able to plan and execute technical dives that require staged decompression and utilize helium-based trimix breathing gas mixtures and EANx and/or oxygen for staged decompression to depths above 240′.

When the Diver gets to the Trimix level they are the most experienced technical divers. Extensive experience in double tanks is needed prior to enrolling in this course. We expect a minimum of 100 dives, 25 of which should have required mandatory decompression. Trimix Divers wishing to upgrade their skill sets, depth rating, knowledge and procedures will move into our Trimix Level II course.

Our Trimix Level II Course will teach you how to safely extend your diving depths down to 330′. The Trimix Level II Course will teach you more advanced methods and procedures. Students will work with up to 3 stage/deco bottles, optimizing your mixes in deeper dives extending your bottom time, offgassing more effectively, the course also dissects expedition trimix diving and what expedition diving is all about. Extensive experience in double tanks is needed prior to enrolling in this course.

For Trimix Level II we would like a minimum of 125 dives. 50 dives should be decompression or mixed gas dives.This is one of the most serious diving courses, as such, candidates should think long and hard about whether or not they should be participating in this program. This basically means, Practice, Practice, Practice before you enroll in this course or you will be re-taking your Advanced Nitrox/Decompression Procedures course over again. This really happens which is why we’re making this point.

Divers crossing into one of our Trimix Courses will be required to do a skills equivalency of all NAUI Intro to Tech Skills in open water prior to acceptance in our courses due to the large number of students we’ve had to retrain.  Upon completion of the intro skills, a decompression checkout will be required as well to check all of the required skills off the list before acceptance.

This course is to provide the diver with the experience and knowledge needed to minimize the risk of diving beyond 73m (240 ft.) while utilizing helium-based trimix breathing mixtures, hypoxic trimix breathing mixtures, helium based and EANx-based travel gases as well as EANx and oxygen during decompression.

Upon successful completion of this course, graduates are considered competent to plan and execute a team- based technical dive that requires travel gasses, staged decompression, helium based trimix breathing mixtures, and EANx and/or oxygen for decompression without direct supervision for dives that exceed 73m (240 ft.) provided the diving activities and the areas dived approximate those of training.
