The Trimix Diver Course consists of two levels, Trimix Diver Level I and Trimix Diver Level II. These courses will give you the skills and knowledge needed to minimize the risks of utilizing helium-based Trimix breathing gas mixes for dives to a maximum depth of 250 fsw / 76 msw requiring stage decompression and utilizing EANx mixtures and/or oxygen during decompression.

Your Trimix Level I instructor will teach you to plan and execute technical dives that require stage decompression and utilize helium-based tri-mix breathing gas mixtures and EANx and/or oxygen for stage decompression to depths above 200 fsw / 61 msw. In your Tri-mix Level II course, you will learn how to safely extend your diving depths down to no greater than 250 fsw / 76 msw.

To enroll in either Trimix course, you must be certified as a NAUI Decompression Techniques Diver and Technical Helitrox Diver or equivalent, and have a minimum of 100 logged dives 20 of which must have been decompression dives.
