What will you learn?

The PADI Tec Trimix Diver course is designed to extend the depth range of technical divers who are already trained and qualified to use air, enriched air and oxygen for technical dives with decompression deeper than 50 meters. Diving with trimix is the extreme limit of technical diving - the maximum depth to use this technology has not yet been defined.

This course is for Tec 50 or Tec Trimix 65 divers (or for divers who have an equivalent certification from another training organization). The course extends the depth range of your abilities by training in the use of trimix (a mixture of helium, oxygen and nitrogen).
