Trimix Instructor
Duration: 4 Days
Dives: 4 Ocean
Age: 21+
Course Highlights
- Train divers in the use of helium-based trimix blends for deep diving, reducing narcosis and managing oxygen exposure.
- Teach gas management skills, including the selection and blending of trimix gases, oxygen management, and calculating gas volumes for extended dives.
- Guide students in the use of both normoxic and hypoxic trimix gases, understanding their applications for various depths.
- Instruct decompression theory specific to trimix diving, including the use of helium for decompression to reduce nitrogen narcosis and oxygen toxicity.
- Teach problem-solving skills at depth, handling gas switching errors, equipment malfunctions, and emergencies specific to deep dives.
- Conduct deep dives with students, focusing on equipment setup, pre-dive checks, and post-dive debriefing to ensure safety and efficiency.
Prerequisites
- Minimum age 2l
- Minimum certification as a TDI Trimix Diver and a TDI Advanced Nitrox and Decompression Procedures Instructor, or equivalent
- Proof of 15 certified advanced nitrox or decompression procedures divers; minimum of 10 must be decompression procedures divers
- Provide proof of 250 logged dives with a minimum of 20 logged Trimix dives outside of training, 10 of these dives must be in the last 12 months
What You Learn
- How to teach the safe use of normoxic and hypoxic trimix for deep diving, with a focus on gas blending, managing helium exposure, and oxygen toxicity.
- Techniques for teaching decompression planning and execution using trimix blends, including gas switching, accelerated decompression, and redundancy.
- Methods for instructing students on managing narcosis, gas consumption, and trimix-specific equipment configurations (e.g., twinset or sidemount).
- Classroom sessions on the physiological effects of deep diving with trimix, emergency procedures for gas failures, and solving complex dive scenarios.
- In-water training for guiding students through dives to depths of 60 to 100 meters, emphasizing safety stops, decompression gas handling, and ascent rates.
- How to demonstrate the use of trimix decompression gases and manage dive emergencies, such as hypoxia or gas toxicity.
HOW TO BEGIN?


Self-Study
