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

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

The NAUI Intro to Tech is also referred to as the Fundamentals of Technical Diving. Explore the hows and why a correct tech system is simple and functional.  You will learn gas calculations way beyond your basic Nitrox. Academics will include learning to calculate MOD (maximum operating depth), END (equivalent narcotic depth), 02 limits (normal and contingency), how to use a matrix, OUT (oxygen tolerance units), and EAD’s (equivalent air depths).

COSTS:   $390 course and instructor fees or $690 for private training
INCLUDES: Academics, open water, NAUI Technical Diver Textbook and C-card.

Student numbers:  minimum 2, maximum 6
Minimum age:  18 years
Basic EANx or equivalent level of training
Proof of 25 logged dives; 10 dives with EANx
Must meet NAUI physical requirements

5 Hours of classroom study
5 Dives
Introduction in demonstrating the fundamental technical diver skills of very good buoyancy and trim while implementing propulsion techniques of the technical frog kick, modified technical flutter kick, technical helicopter turns; clockwise and counter clockwise and being able to perform a back down (kicking in reverse).

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 & Helitrox Diver       

This course is to provide the diver with a working knowledge of the theory, methods, and procedures of planned staged decompression diving while using optimal breathing gas mixtures. As a part of the course students will plan and conduct a standard staged decompression dive not exceeding a maximum depth of 130 feet (40 m). Equipment requirements, team requirements, NTEC configurations, decompression breathing gas mixtures (oxygen and EANx), and decompression techniques.

$600 includes course and instructor fees per student (class of 3 or 4)
$900 per student for class of 2
$35 per c-card: one card for NAUI Technical Decompression and one card for Helitrox Diver
plus gas fills and boat charters

Student numbers:  minimum 2, maximum 4
Minimum age:  18 years
Basic Nitrox and Intro to Tech or equivalent certifications
Minimum logged dives:  50, 15 utilizing EANx

20 hours of classroom study
10 dives minimum
Advance student’s working knowledge of EANx and Helitrox diving
Learn theory and methods involved in decompression diving
Conduct staged decompression dives utilizing standardized gases (oxygen, helium, nitrox and air). Become qualified to dive to 150 feet on Trimix using Oxyen for decompression
Prepare diver for full Trimix training

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).

Tuition: $750.00 Academics 18 hours      Open Water Dives 8

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.

Academics 4 hours         Open Water Dives 1

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.

Tuition: $750.00 plus cost of boat charter Academics: 8 hours      Open Water Dives: 4
