PADI Tec Trimix 90

For the extreme diver ready to further explore the world of technical deep diving, the gas of choice is Trimix – a blend of oxygen, helium and nitrogen. 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 – if any – ever see.

The PADI Tec Trimix 90 Diver course is intended to extend the depth range of technical divers already trained and qualified to use air, enriched air and oxygen for technical decompression dives beyond 50 metres/165 feet. The maximum depth you’ll dive in this program is 90metres. Once you’ve earned this certification as a Full Trimix diver, with more experience diving to 90m and beyond, exploration options become endless, excitement levels rise thru the roof as you start planning and executing unbelievable dives that before you started your technical development, you never thought were possible.

Diving with trimix is the outer edge of Tec diving – the maximum depth for using this technology has yet to be defined. This course is for Tec 50 or Tec Trimix 65 divers.
