The IANTD Trimix Course trains technical divers to operate in very deep water. The knowledge, skills and procedures taught in this course are more than adequate to qualify divers to perform dives as deep as 100m/330ft. Hypoxic gases, multiple decompression gases and stage diving techniques are all explored during training.
We are fortunate at Tech Asia. If we want to make a 90-100m/300ft. dive we only need to travel about ten minutes to be able to do it. For an IANTD Trimix Diver, the Deep Atolls is a perfect example. From about 66m/220ft on down this unusual, eerie landscape creates a feeling that anything can happen. This is prime Thresher Shark country but the impression you have is that everything is ancient and been undisturbed for ever. Groupers can be so large you can imagine them to be a hundred years old, battle scarred old rays buried in the seabed...every dive here is memorable. This is also the minimum certification you need for us to take you to the bottom of 100m wall at Hibo Reef, and the most challenging parts of Blackfish Pinnacle, equally as atmospheric. Or are you thinking of a wreck dive? The Princess of the Orient, a huge ship sunk in a typhoon just outside Manila Bay, would now fall in to your range of possibilities!
Prerequisites
Program Content and Limits
During the IANTD Trimix Diver course you will further develop what you learned during Normoxic Trimix Diver or Technical Diver into increasingly more complex dive scenarios. Dive planning becomes even more important to understand due to depth, potential oxygen exposure and gas required in the event of a problem requiring sharing, or loss of a decompression gas. All can be managed but how to perform a very thorough "what if" analysis needs to be understood when making such deep dives. Expect to look at different kinds of dive profiles and discuss whether you are better served using three decompression gases, or two deco and a stage of bottom gas for example.
During the classwork, land drills and in water you will learn about :
Note: As with other IANTD programs, the diver must complete and pass the written examination, complete all open water requirements efficiently and safely, and meet all criteria on the final Course Evaluation Form in order to be certified.
You will find details of what is included and not included across all IANTD courses on the Overview page.
The IANTD Trimix course is normally taught in double tanks although Sidemount can be used by those already certified. The use of three decompression tanks, or two decompression and a bottom stage, is practiced during training.
For this level of diving, to reduce exertion at depth and make for the most succesful dives, use of a DPV if you are qualified to do so is highly encouraged. We do offer training and rental if you need it.
Gas cost on this course can be quite variable depending on the number of people in the class, and the profiles you decide to make during training. As a rough guide, expect Helium to cost between $450-700/ Php 22,000-35,000.
