TDI Trimix

ScubaQuest Diving Logo

As your motivation to explore progresses you may find that you wish to go deeper to dive that historical wreck or that cave system that you have read so much about. Alternatively you may just want to continue your journey and learn new skills and techniques.

One of the limiting factors of diving deeper is gas narcosis; TDI’s Trimix diver course shows you how to minimise the effects of gas narcosis by using helium in place of a percentage of the nitrogen in your breathing gas.

During this 4 day course you will be shown how to competently and safely utilise how to plan for dives using helium in the back-gas, the limitations of using helium and the impact of helium on decompression.

Qualification Depth
60 meters maximum using Trimix as back-gas – Oxygen content no less than 18%.

Utilising up to 100% oxygen for accelerated decompression.

Course is performance based.
