TDI CCR Air Diluent Decompression (45m)

TDI CCR Air Diluent Decompression (45m)

Are you an open circuit technical diver (ie TDI Decompression Procedures Diver or equivalent) 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 using air diluent.

How do I begin?

You start with the training materials, if you did not get them with a 30m course. We will provide you with and TDI CCR online code for the Megaladon, Pathfinder and SF2 courses and the TDI manual for APD's Inspiration and Evolution units so you can do all your studying at home before you come to the dive centre. You also need to have a copy of the manufacturer's manual for the specific unit.
