Technical Equipment Configuration

The Technical Equipment Configuration is called the NAUI Technical Equipment Configuration, or just simply NTEC.  A Technical gear configuration does not always mean twin cylinders with dual regulators.  The NTEC principles can be applied to a single cylinder unit or to a twin cylinder unit.  For a visual understanding of true technical diving gear, click www.halcyon.net.

A description of the NTEC is a simple and coherent Scuba System that applies uniformity in the arranging and usage of regulators plus the specific placement the following essentials: cutting tool(s), SPG, computer, compass, surface marker and line reel(s).

Step One:  Attend a NTEC seminar.  During this seminar you will be able to touch, feel and learn how Universally Functional a NTEC unit is.  You can even set up a pool demo dive.

Step Two:  Enroll into the Intro To Technical Diving Course and learn not only how to set-up a Technical Diving Unit, but also how to dive your single cylinder and a set of doubles.

Intro to Tech

Learn the Fundamentals of Technical Diving....

This course gives the recreational diver the ability to increase their confidence and develop technical diving skills within the non-decompression range of sport diving.

Focus is on: technical buoyancy and trim, propulsion techniques of a frog kick, modified flutter kick, helicopter turns and back downs, underwater surface marker deployment, out of air sharing through a confined area, gas switching, simulated decompression stops and line reel usage.

All training is executed while diving a correctly configured Technical Diving Rig.

Each diver utilizes a technical depth and time matrix, calculates gas consumption for the swimming portion and at the stage stops, oxygen toxicity exposures and inert gas absorption calculations.

Upon completion of the NAUI Intro to Tech, the student is considered to be competent to enter into a NAUI Technical Diver Courses such as Decompression Techniques, Helitrox Diver and Technical Diver EAN.

Technical Decompression Diver

This course provides the diver with a working knowledge of the theory, Open Water decompression techniques, and procedures of planned stage decompression diving.   The NAUI RGBM Dive Tables and NAUI RGBM GAP Software are used as the bases of calculating your stage decompression dives. 

As a part of the course, students will plan and conduct standard stage decompression dives to a maximum depth of 130 fsw.  When the Decompression Techniques Course is combined with the Helitrox Course, then standard stage decompression dives will be executed to 150 fsw.  Team requirements, NTEC configurations, decompression breathing gas mixtures (including Oxygen, Helitrox, and EANx) are covered.

Upon successful completion of the NAUI Decompression Techniques Course, graduates are considered competent to plan and execute dives that require stage decompression utilizing air and EANx mixtures from 28%  to 100% oxygen for decompression.   A combination of shore based and boat based dive sites will be utilized in the Great Lakes Dive Region.

Academics: 12 hours   Open Water dives 7 or 10 when combined with the Helitrox Course.

Helitrox Diver

As shallow as 80 feet, nitrogen narcosis starts to alter our reasoning and dive planning ability.  Even as shallow as 100 to 120 fsw, a diver can unknowingly become intoxicated. EANx mixtures do not fix the narcosis problem. The only way to reduce nitrogen narcosis at depth, is to reduce ones exposure to nitrogen. 

Helitrox gas mixtures are extremely advantageous due to the reduced nitrogen narcosis.  helitrox gas is a trimix, consisting of oxygen (26-30%) and helium (13-17%). These percentages result in shorter decompression stops than the lower oxygen and higher helium mixtures for the deeper diving helium.

Divers, who use helitrox for the first time, are amazed at how many details they remember.  They find themselves diving wrecks they had been on numerous times while breathing air or nitrox, and are now noticing and remembering details previously overlooked.

Trimix Diver

The NAUI Trimix Diver course provides you with the skills and knowledge needed to minimize the risks of utilizing helium-based trimix breathing gas mixtures for dives to depths not exceeding 200 fsw (61 msw) requiring staged decompression and utilizing EANx mixtures and/or oxygen during decompression.

Learn how to plan and execute technical dives that require stage decompression and utilize helium-based trimix breathing gas mixtures with EANx as a travel gas and oxygen for decompression to depths not exceeding 200 fsw (61 msw).

Extreme Exposure Diver

This course is to provide the diver with the experience and knowledge needed to minimize the risk o diving beyond 200 fsw while utilizing helium-based trimix breathing mixtures, hypoxic trimix, helium-based and EANx-based travel gases as well as EANx and oxygen during decompression.

Mixed Gas Blender and Oxygen Service Technician

The NAUI mixed Gas Blender and Oxygen Service Technician course provides you with the skills and knowledge needed to safely handle high pressure gases, prepare oxygen enriched air and helium-based mixtures, and prepare equipment for oxygen service.

Analyze the resulting breathing gas mixtures from your own breathing gas blending practice and master the breathing gas blending system used in training. This is a great course if you plan to work in a dive center and need additional training or if you wish to expand your knowledge of diving gas mixtures.

You must be at least 18 years of age to enroll in the NAUI Mixed Gas Blender and Oxygen Service Technician course.

Academics 8 hours    Practical Application 4 -5 hours

Wreck Penetration Diver

The NAUI Wreck Penetration Diver course provides you with the skills and knowledge needed to minimize risks in penetration wreck diving at depths not exceeding 130 fsw (40 msw). Wreck penetration diving is any diving inside a sunken vessel, aircraft, or similar structure.

Learn about the safety hazards and special risks of overhead environments, gas management, entanglement, limited visibility, specialized equipment utilized in wreck penetration diving, search methods, underwater navigation, legal aspects, artifacts, treasure, salvage, archaeology, and more.

You must be at least 18 years of age to enroll in a NAUI Wreck Penetration Diver course. You must also be certified in NAUI Introduction to Technical Diving and be a certified NAUI EANx Diver (or their equivalents), and have a minimum of 50 logged dives with at least 15 EANx dives.
