Advanced Mixed Gas CCR
The Advanced Mixed Gas CCR course prepares divers to take their rebreathers as deep as 100 m/330 ft using hypoxic Trimix as a diluent.
Needless to say, you need to spend considerable time diving your CCR in shallower water before taking this final step.
The course generally takes at least four days and eight dives. You can sign up in person, over the phone or online by clicking the button below. If you sign up online, you will still need to call to schedule your class.

The Advanced Mixed Gas CCR course prepares divers to take their rebreathers as deep as 100 m/330 ft using hypoxic Trimix as a diluent. At these depths, many things change including:
- You will need substantially more open-circuit bailout gas at these depths than you do in shallower water.
- Contingency planning must be more precise and cover a greater range of “what if?” scenarios.
- You are going to be spending more on helium even though the helium in the loop is being recycled.
Needless to say, you need to spend considerable time diving your CCR in shallower water before taking this final step.
Important: Be aware that all CCR training is unit-specific. You are not certified to dive any CCR; just the specific make and model on which you trained.
