Trimix Diver
Add helium and go deep — the gateway to serious exploration.
About The Course
Beyond about 45–60 metres, nitrogen narcosis and gas density become the real hazards. Trimix adds helium to your breathing mix to keep your head clear and your work of breathing low where it matters most.
This is normoxic trimix — helium in the mix, a breathable bottom gas, and the certification that opens the Red Sea’s deeper wrecks and walls. When you are ready to go past 60 m, Advanced Trimix is the next rung.
