Become a CCR Technical Extended Range Diver with SSI

Are you ready to push your diving that little bit further? This program provides the training you need to independently plan and conduct trimix diluent decompression dives to a maximum depth of 60 meters using a closed-circuit rebreather and a minimum of two bailout cylinders. It builds upon your basic rebreather skills and helps you to develop a problem-solving attitude and approach that facilitates longer decompression dives.

This challenging SSI certification program develops your ability to think about and respond to emergencies as a well-rounded, competent rebreather diver. With safety at the forefront of the SSI training philosophy, this unit-specific program contains in-depth academic topics, such as gas density, to enable safe diving. With training available on either a rEvo, JJ, SF2, AP Inspiration, Prism 2, or Poseidon CCR, this program increases diver safety by only using trimix as the breathing gas to reduce gas density.
