The SSI CCR Extended Range course builds on the skills and techniques you have learned in your diver training - extending depth and duration and adding decompression and more complex skills. Training can be done with an rEvo, JJ, AP, Poseidon or SF2 rebreather. SSI has developed this unit-specific course to be able to use a breathing gas with Trimix that reduces gas density and increases diving safety. Your CCR Extended Range certification qualifies you to conduct decompression dives to a depth of 45 meters using Trimix as a diluent. Take your dive planning to the next level with the exciting possibilities of closed circuit rebreathers. Start online today!
