NAUI Technical Diver Level 1 (TECH 1)

The Technical Diver Level 1 (Tech 1) course is structured to prepare divers for the rigors of technical diving and to familiarize them with the use of different breathing and decompression mixtures. Tech 1 training focuses on expanding the fundamental skills learned in the GUE Fundamentals course (or elsewhere), and is designed to cultivate, integrate, and expand the essential skills required for safe technical diving. This will include problem identification and resolution, and building the capacity for progressively more challenging diving. In this class, students will be trained in: a) the use of double tanks/cylinders and in the potential failure problems associated with them; b) the use of Nitrox for accelerated and general decompression strategies; c) the use of Helium to minimize narcosis; and d) the applications of single decompression stage diving with respect to decompression procedures.
The class will focus on enriched air and Helitrox (Helium enriched gas), as flexible and beneficial breathing gases for dives in the 40 foot/12 meter to 150 foot/45 meter depth range, and provides an excellent foundation on which divers can build their technical diving experience and prepare for NAUI’s Technical Diver 2 course (Tech 2).
The course will consist of three classroom sessions and a minimum of 15 open water dives. Upon successful completion of this course, you will receive a NAUI Advanced Nitrox, Staged Decompression and Helitrox certification and may engage in decompression diving activities utilizing nitrox or helitrox with nitrox decompression to a maximum depth of 150 feet.
