JJ-CCR Air Diluent Decompression
The popular second-level CCR certification for air or helitrox decompression diving.
The Air Diluent Closed Circuit Decompression course is probably the most popular of the CCR courses. It is the second-level certification for divers wishing to use a closed circuit rebreather for air or helitrox decompression diving, and is ideal for technical divers transitioning from open to closed circuit.
The objective is to train divers in the benefits, hazards and proper procedures for diving a CCR and to develop advanced CCR diving skills, to a maximum depth of 40 metres using an air diluent for formal decompression diving, or 45 metres using Helitrox.
