The TDI Closed Circuit Rebreather (CCR) Air Diluent Diver Course is your first step into closed circuit rebreather diving and your first truly quiet dive experience! Using the latest technology in CCRs can maximize your gas supply and provide an optimum breathing gas for any depth by maintaining a constant partial pressure of oxygen. It’s like having a nitrox blending machine on your back!

During this course I will teach you all of the necessary skills to conduct no decompression CCR dives to a maximum depth of 30 metres/100 feet using air diluent.

This course is for you if you are looking to advance your diver level training and equipment configurations by learning to dive a rebreather. Whether you are an avid photographer, want to experience the silence of diving a rebreather, or looking to get closer to the marine life – rebreather diving is for you.

This course is accompanied by a service and repair workshop for in-field problem solving and maintenance; setup and maintenance of the unit, loop volume management, calibration of electronics, emergency procedures, buoyancy control, CNS tracking.
