IART

This course is designed to provide experience and training for mixed gas diving with the CCR Rebreather to a maximum depth of 100 msw. The CCR III Diver course gives the opportunity to safely learn the techniques and theory for decompression dives with helium based mixes as a diluent.

All theoretical and practical aspects of Trimix or Heliox diving with the CCR Rebreather. The classroom sessions should explain the physical and physiological hazards of mixed gas diving, decompression planning, some equipment considerations for mixed gas diving such as diluent and bail-out selection, and all the procedures involved. An important point is dive planning using computer-based dive tables.
