JJ-CCR Air Diluent Diver
Your first step into rebreather diving and your first truly quiet dive, to 30 metres on the JJ-CCR.
The Air Diluent Closed Circuit Rebreather course is your first step into rebreather diving, and your first truly quiet diving experience. Using the latest technology, CCRs maximise your gas supply of nitrox and provide the optimum breathing gas for any depth by maintaining a constant partial pressure of oxygen.
This course develops the abilities, knowledge and techniques to dive responsibly and safely with the closed circuit JJ-CCR within sport diving and no-decompression limits. Over a minimum of seven dives, your TDI Instructor teaches you all the necessary skills to conduct CCR dives to a maximum depth of 30 metres. The unit-specific manual must be studied prior to any training.
