This Program is designed for those individuals already involved in deep diving activities. Trimix affords a safer means for deep-water exploration for divers who must dive deep or perform with a clear head at the intermediate depths. Trimix means a mix of three components ("tri" and "mix"), and usually when people talk about trimix, they mean the mix of oxygen, nitrogen and helium. Trimix is used in very deep dives instead of air to reduce the partial pressure of oxygen (to avoid oxygen toxicity) and nitrogen (to avoid nitrogen narcosis). Trimix is also being used as travel gas or deco gas, depending on the situation.

The percentages of gas components vary depending on the dive. As one goes deeper, there will be less oxygen and nitrogen, and more helium. Trimix mixes are labeled for example as "Trimix 10 50" or "Trimix 10/50", where 10 represents the percentage of oxygen in the mix, and 50 is the percentage of helium.

- Minimum age: 18 years old
- Must be qualified as a Technical Diver or Technical Cave Diver or Technical Wreck Diver or Normoxic Trimix Diver or equivalent.

Minimum of 200 minutes of open-water run time completed within three Trimix dives to depths between 50 meters and 79 meters. All depths must be worked towards incrementally, with no increase greater than 12 meters from one dive to the next. One dive must be to at least 60 meters or deeper. Theory will be covered between dives. Pre reading will help the smooth running of the course. Recommended twin 10/12 cylinders with manifold (preferably with Isolator).
