IART CCR Level-3 Advanced Trimix


This course is designed to provide experience and training for mixed gas diving with CCR to a maximum depth of 90 msw. The CCR Level III diver course gives the opportunity to safely learn the techniques and theory for decompression dives with helium based mixes as a diluent.

※Diver qualified on specific rebreather such as rEvo, Prism 2, Megalodon, Inspiration Classic/Vision, Evolution, Kiss Classic, SF2 Back mount/Side mount, Liberty

  4. valid diving medical.


OPTION B (4 dive course)

  1. Minimum of 18 years of age

  2. IART CCR Level II Extended Range (normoxic Trimix) Diver or equivalent

Content/Course minimum

  1. All theoretical and practical aspects of Trimix or Heliox diving with the CCR.

  2. 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 such as Z-Plan, ProPlanner, etc.
