Expedition Level Trimix Rebreather Training
Train for deep expedition-level CCR diving with the TDI Advanced Mixed Gas CCR Diver Course in Thailand. Learn advanced trimix decompression procedures, deep bailout planning and trimix CCR diving techniques beyond 60 metres with experienced technical diving instructors.
TDI Advanced Mixed Gas CCR Diver Course
The TDI Advanced Mixed Gas CCR Diver Course in Phuket, Thailand represents the highest level of recreational and technical rebreather diver development before full exploration and expedition diving.
This advanced trimix CCR program trains experienced technical divers to safely plan and execute deep staged decompression dives using helium-based mixed gas diluent on a closed circuit rebreather beyond 60 metres.
The course focuses on expedition-level technical diving procedures, advanced bailout strategies, deep decompression planning and operational CCR problem-solving under realistic technical diving conditions.
For divers pursuing deep wreck exploration, advanced cave diving or expedition-level decompression diving, Advanced Mixed Gas CCR training is the next major progression step.
