Tec Trimix 65


This course opens up the advantages of trimix to the diver, and divers are qualified to make multi-stop decompression dives that employ EANx and oxygen for accelerated decompression, and any trimix with an oxygen content of 18% or more allowing the diver to dive to a maximum depth of 65 metres/210 feet.

The PADI Tec Trimix 65 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.

This course is for Tec 50 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).

You will plan and execute at least five dives using EANx and trimix blends, use decompression software to create custom dive tables and dive plans and make training dives as deep as 65 metres/210 feet.
