The NAUI Helitrox Diver course provides the training and experience necessary to understand the hazards of utilizing helium-enriched EANx for dives to depths not exceeding 150 fsw (46 msw) that may require staged decompression, utilizing EANx mixtures and/or oxygen during decompression.
What You Will Learn
Your NAUI Helitrox Diver course includes a minimum of four open water dives using a Helitrox mixture (26% oxygen / 17% helium); one dive is a repetitive dive. This course provides you with the training and experience you need to competently plan and execute extended range dives that require stage decompression utilizing Helitrox and oxygen.
Topics covered in your training include oxygen toxicity and nitrogen narcosis limitations; emergency planning including omitted decompression, decompression sickness, and equipment failure; emergency and contingency procedures; entry and descent techniques; variable ascent-rate techniques and deep-stop models; tethered or un-tethered decompression methods; shore or boat based dive team support and chamber locations; and NAUI Technical Equipment Configuration (NTEC).
How Do You Get Started?
You must be at least 18 years of age to enroll in the NAUI Helitrox Diver course. You must also be a certified NAUI Technical Decompression Diver (or its equivalent), and have a minimum of 50 logged dives with at least 15 EANx dives.
