Tec Trimix Diver



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.


What do you need to start ? 

You must be:

Be a PADI Rescue Diver or equivalent and having proof of CPR and first aid training with the previous two years.
Be certified as a Tec 50 or Tec Trimix diver or equivalent
Be at least 18 years old
Have logged at least 150 dives
Have a medical form signed by your physician


What will you do during Your PADI Tec Trimix course? 

You will:

Plan and execute at least five Trimix decompression dives using various Trimix blends
Use decompression software to create custom dive tables and dive plans
Make training dives as deep as 75 metres
The PADI Tec Trimix 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. 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 (or those holding a qualifying certification from another training organization). The course extends your depth range capabilities by training you to use Trimix (a blend of helium, oxygen and nitrogen).
