The SSI CCR Hypoxic Trimix program provides divers with the knowledge and experience required to independently plan and conduct unlimited trimix decompression dives to a maximum depth of 100 meters using a closed-circuit rebreather and a minimum of three bailout cylinders. This in-depth closed-circuit rebreather diving program is both physically and mentally challenging, holds the highest level of accolade in the industry, and reflects your commitment and experience as a diver. With safety at the forefront of the SSI training philosophy, this unit-specific program will provide more in-depth academic topics such as gas density, team bailout protocols, and expedition procedures to enable safe diving. This unit-specific program is available on the rEvo, SF2, AP Inspiration, Poseidon, Prism 2, or JJ rebreather and only uses trimix as the breathing gas to reduce gas density.
