NAUI’s Closed Circuit Mixed Gas Diver course will to provide you with the skills and knowledge needed to minimize the risks of utilizing helium-based or trimix breathing diluent gas mixes for diving, with dive parameters to a maximum depth of 250 fsw / 76 msw requiring decompression with rebreathers and constant PO2.
Your training will include dive planning limits based on gas consumption of bailout stages, oxygen exposures, inert gas loading and breathing gas mixtures; navigation, diver rescue and management of a diver experiencing oxygen toxicity; ascents with ascent reel and lift bag; and stage decompression.
The Closed Circuit Mixed Gas Diver course is an intensive class that requires previous certifications in NAUI Decompression Techniques, Heliair, and Closed Circuit Rebreather (CCR) or the equivalents thereof, plus a minimum of 100 logged hours on a Closed Circuit Rebreather, 60 hours of which are directly on the specific CCR for mixed gas training.
