TDI Mod 2: Mixed Gas CCR
June 12, 2025 - June 17, 2025
The TDI Mixed Gas CCR (TDI MOD 2) teaches experienced divers to use mixed gas containing helium in order to better control the effect of nitrogen narcosis.
Rebreathers are able to maximize your gas supply and provide the optimum breathing gas for any depth by maintaining a constant partial pressure of oxygen (PPO2). With this training module, your understanding of what is going on in your rebreather will take a huge leap forward.
To dive a depth range of 45 to 6 m, you will need the addition of helium as a diluent and this course will teach you:
- CCR diving skills appropriate to technical diving to a maximum of 60m
- Benefits, hazards and proper procedures for mixed gas diving
Instructor: Sameh Sokar
This course is open and can be taught on either the JJ-CCR, rEvo, or Liberty (Sidemount and Backmount)
