TDi Trimix Diver Course The TDI Advanced Trimix Diver Course is the top level of training for open circuit divers wishing to dive to depths as deep as 100 metres/330 feet utilizing hypoxic levels of
oxygen (below 17 percent). This course is perhaps one of the most informative and challenging of all of the TDI open circuit courses. Upon completion, you will be among some of the
most elite divers, capable of doing and seeing more while diving than any other divers out there.

HPNS and isobaric counter diffusion
Decompression gas choices
Tables vs. personal dive computers
Emergency and contingency planning (equipment failure, omitted decompression, etc.)

Decompression diving procedures Equipment selection
Pre-dive checks and drills
Stress analysis and mitigation
Following a decompression schedule
