CCR Cave

Diving with a rebreather in a cave system is very intriguing, but there are special rules to follow. You must constantly control your PO2, determine distances, perform bailout calculations, train emergency procedures for equipment failure, and more. The CCR Cave course teaches you the handling and safe planning of a rebreather, plus the standard exercises of a conventional open-circuit cave diving program. It is certainly considered to be the toughest training program in technical diving and is intended for those who are already very familiar with their own rebreather and have mastered the device with all its features.

At Protec Sardinia, we teach CCR Cave courses on the most popular rebreather models on the market right now, and are certified instructors of the devices.
