Are you an open circuit technical diver looking to cross over to the “silent” side? Or maybe you are a CCR Air Diluent Diver looking to progress to the next level? Either way, TDI’s CCR Air Diluent Decompression Course is the next step.Using the latest technology in CCR’s can maximize your gas supply and provide an optimum breathing gas for any depth by maintaining a constant partial pressure of oxygen. Like having a blending station on your back, a CCR is the ultimate tool for technical divers.

During this course, your TDI Instructor will teach you all of the necessary skills to conduct decompression CCR dives to a maximum depth of 45 metres/150 feet using air diluent.
