TDI CCR AIR DILUENT (30m)

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!  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.

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, your TDI Instructor will teach you all the necessary skills to conduct no decompression CCR dives to a maximum depth of 30 metres using air diluent.

Courses are available for APD units, Meg, Pathfinder and SF2.
