The PADI Tec Trimix Diver course takes you to the outer edges of technical deep diving, opening the door to pristine dive sites few divers have ever seen.  This is the ultimate open circuit diving qualification


What you will learn

This course extends and expands the skills of the Tec Trimix 65 diver by continuing the development of strategies for overcoming oxygen and nitrogen gas limitations for deep technical decompression diving. Training dives are limited to 95m, but once qualified and after more experience, divers can plan and execute dives to deeper depths

Certified Tec Trimix  divers are qualified to make multi-gas decompression dives using a Hypoxic Trimix blend.  That is, a blend that contains an Oxygen level of less than 18% and could be as low as 9% (depending on the planned depth) Helium and Nitrogen. You will use more stages for Travel and multiple Stages containing EANx gases for accelerated decompression.
