TDI MOD 1 CCR Air Diluent (30 m) - Transform Your Diving Forever
The TDI Closed Circuit Rebreather (CCR) Air Diluent Diver Course is your first step into closed-circuit rebreather diving, and your first truly quiet dives. By using the latest CCR technology, you’ll significantly extend your gas supply while breathing an optimal gas mixture at any depth through constant oxygen partial pressure control. Simply put, it’s like carrying a nitrox blending station on your back.
This course trains you to safely conduct no-decompression CCR dives to a maximum depth of 30 metres / 100 feet using air diluent, under the guidance of an experienced instructor.
This course is currently available on the CCR Divesoft Liberty Sidemount.

What’s In It For You?
✅ Independent CCR Diving: Upon successful completion, you may dive the CCR you were trained on without direct instructor supervision, provided conditions are similar to training
✅ Extended Dive Capability: Conduct silent, efficient no-decompression CCR dives
✅ Strong Technical Foundation: Build the essential base for further CCR and advanced technical training
Graduates may dive to a maximum depth of 30 metres / 100 feet, with no decompression, in environments and conditions similar to those encountered during training.
The TDI e-Learning materials are accessible in multiple languages. At B&W Diving, we are pleased to provide in-person dive training in English, French, Spanish, and Japanese.
