Normoxic Trimix

Why IANTD Normoxic Trimix Diver?

The IANTD Normoxic Trimix program provides training to those divers who wish to dive to depths between 39 msw and 60 msw. This program teaches divers to use an Equivalent Narcotic Depth (END) of 36m or less to reduce the effects of Nitrogen Narcosis when diving in the 39 to 60 msw range. Normoxic Trimix reduces narcosis on dives to such depths thus allowing divers to operate more safely and efficiently.

What do you need to start?

  • Be an IANTD Advanced EANx Diver or IANTD Advanced Recreational Trimix Diver.
  • Have a minimum of 100 logged dives of which at least 30 must be deeper than 27 metres.
  • Be a minimum of 18 years of age.

What will you do?

During the IANTD Normoxic Trimix Diver course you will learn two stage cylinder decompression techniques. You will also be able to dive to a maximum of 60 metres and use nitrox (up to 100%) for accelerated decompression.

Dive details

Course timing is flexible dependant on weather (to access required dive sites) and participant availability. The course includes 5 evenings of theory, 1 confined water session and 4 boat dives.  Open water dives are conducted with teams of no more than 3.
