CCR Air Diluent Course
What is a closed-circuit rebreather?
Closed-circuit rebreathers are a type of scuba that reuses the gas you exhale. This is the primary difference between CCR and open-circuit scuba.
Background on Closed Circuit Rebreathers
Technical diving has been revolutionised by the development, availability and reliability of Closed Circuit Rebreathers. CCRs provide numerous benefits to the technical diver, including: reduced gas consumption, optimum EANx blends for decompression and a wider range of solutions to equipment problems. Consequently CCRs potentially allow the technical diver a greater access to time underwater - greater time based on gas logistics when compared with an open circuit technical diver and more time available to find solutions to gas management problems.
What Will You Learn?
The CCR Air Diluent course teaches you to assemble, test and dive a rebreather to a maximum depth of 30m. The course is conducted over five days, with a gentle progression of skills as you become more familiar with rebreather diving. There is no rebreather experience necessary to begin the programme - divers aged 18 and above with at least 20 logged dives and an Enriched Air Diver certification may take the course.
- Minimum age 18
- Provide proof of 20 logged open water dives. If completing a unit crossover, provide proof of 10 logged CCR dives in the last 12 months.
- Provide proof as a TDI Nitrox Diver or equivalent
