SSI CCR Technical Extended Range

Course Overview & Training Objectives

SSI CCR Technical Extended Range trains rebreather divers to conduct multi-stage decompression trimix dives to 60 meters. Helium diluents mitigate narcosis and gas density while students manage complex team-level bailout plans and gas logistics. Divers master long-stop decompression profiles, offboard gas integration, and multiple stage bottle manipulation.
