Tec Trimix Diver


Tec Trimix Diver Course

This is the final module in the range of technical diving courses and it will take you to the outer edge of technical diving.

You will be able to join the ranks of the few divers qualified to explore and expand the boundaries of diving.

The course builds upon the skills and knowledge learned in the Trimix 65 course focusing on mission application, dealing with hypoxic gases, gas selection options, different decompression models as well as planning and executing complex dives in a save and precise manner while handling potential problems efficiently.

Training dives may be executed to a maximum depth of 90m / 300ft. Once certified, this course qualifies you to plan and execute hypoxic Trimix dives to 90m / 300ft and gradually build experience to dive beyond those depths.


All equipment rentals, EANx & TMx breathing gases, and tuition in open water.
