TDI Trimix Diver Technical Diving Course at TecEvolution Thailand, Koh Chang

TDI Trimix Diver Course, Why ?

As your motivation to explore progresses you will find that you may want to go deeper to dive that wreck that is part of history or that cave system that you have read so much about. One of the major limiting factors of going deeper is narcosis.

This course provides the training required to competently and safely utilise breathing gases containing Helium for dives that require staged decompression, utilising Nitrox and/or Oxygen mixtures during decompression to a maximum depth of 60msw.

In previous courses you will have learnt that Nitrogen is reduced in the breathing mix by adding Oxygen. The downside is that the depth is reduced because of the possibility of CNS Oxygen Toxicity.

Simply, by adding Helium, the narcotic effect of the breathing mix is lowered while keeping the Oxygen values in an acceptable range. Helium has almost no narcotic effect on the human body and is reasonably easy to obtain thereby making it the logical choice for deeper diving, safely.

Diving at the TDI Extended Range or TDI Trimix Diver level requires discipline. Expect your adventure to be a challenge!

This course is well suited to be undertaken in conjunction with the TDI Extended Range course

Be a TDI Advanced Nitrox Diver and TDI Decompression Procedures diver (or equivalent)
