TDI TRIMIX COURSE

NORMOXIC 

This TDI TRIMIX COURSE available in Phuket Thailand provides the TDI diving course training required to competently and safely utilize breathing gasses containing helium for dives that require staged decompression, utilizing Nitrox and/or Oxygen mixtures during decompression to a maximum depth of 200fsw/60msw.

As an alternative to TDI Extended Range Diver which uses air, on this course you dive up to 60m with trimix. Trimix is a blend of oxygen, helium and nitrogen. This enables you to dive within air limits, with reduced narcosis levels. The TDI Entry Level Trimix course introduces you to diving with trimix containing minimum 18% oxygen. You learn how to consider both the benefits and hazards of diving with trimix.

    • Maximum depth: 60m
