The Helitrox Diver course teaches you how to plan and execute Helitrox-based dives that may require stage decompression and utilize EANx and/or O2 for stage deco. This course is designed to teach you the hazards of utilizing HE for dives to a max depth of 150 fsw / 46 msw. During your training, you’ll complete at least four open water dives using a Helitrox mix (26% O2 / 17% HE) of which at least one will be a repetitive dive. Your studies will include gas needs and requirements, O2 toxicity limitations, nitrogen narcosis limitations, and emergency planning, including omitted decompression, DCS, and equipment failure. Topics covered will also include emergency and contingency procedures, entry, ascent, and descent techniques; deep-stop models; diver trim, ballast and buoyancy compensation; tethered or un-tethered decompression methods; shore or boat based dive team support and chamber locations; communications and emergency breathing gases; and NAUI Technical Equipment Configuration (NTEC). As you continue your technical diver training, you’ll take is Decompression Techniques, in which you will gain a working knowledge of the theory, methods and procedures of planned stage decompression diving. Your training will include a minimum of six dives including planning and executing a standard stage deco dive less than 130 fsw / 40 msw. Your instructor will also teach you equipment requirements including team requirements and NTEC, and decompression breathing gas mixtures (including oxygen, Helitrox, and EANx). You’ll learn the practical skills and knowledge you need for decompression diving within course parameters. If you are 18 years of age, posses at least NAUI Master Scuba Diver, Adventure Scuba’s Ultimate Advanced and Technical EANx Diver certifications (or their equivalents), and have 75 logged dives, you may enroll in the Decompression Techniques course.                                                                                                                                           Call for pricing.
