TDI CCR Air Diluent Decompression Diver Course
Train with Warrior Dive Adventure – Extend Bottom Time and Dive Deeper with Closed Circuit Rebreathers
Unlock new depths and longer bottom times with the TDI CCR Air Diluent Decompression Diver Course, proudly offered by Warrior Dive Adventure. This advanced-level rebreather course teaches divers to conduct decompression dives using air as a diluent on a closed circuit rebreather (CCR), with a maximum depth of 45 metres (150 feet).
Using modern CCR technology, you’ll maintain a constant partial pressure of oxygen, maximizing your gas supply while optimizing your breathing mix at depth—just like having a portable gas blending station on your back.
This is the ultimate tool for divers serious about technical diving, deeper exploration, and precision dive planning.
Why Take the CCR Air Diluent Decompression Course?
Closed circuit rebreathers offer significant advantages over traditional open circuit scuba systems, especially for deep and extended-range dives. This course gives you:
The ability to conduct decompression dives up to 45m
Advanced knowledge of CCR mechanics, physiology, and planning
Mastery of unit-specific systems, gas tracking, bailout procedures, and more
The foundation for further CCR certifications like TDI Mixed Gas CCR Diver (60m)
Whether you’re transitioning from open circuit tech or looking to take your CCR diving further, this program delivers the skills and safety protocols you need to dive longer, deeper, and smarter.
