TRIMIX DIVER
Are you looking to expand your depth range? Do you want to reduce narcosis during deep dives? The Trimix Diver Course could be your next step! 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; Trimix Diver course shows how to minimise the effects of narcosis by adding helium to offset the nitrogen in your breathing gas. While taking the Trimix Diver course your Instructor will teach you how to plan and execute dives utilising as little as 18 percent oxygen and diving to maximum depth of 60 metres/200 feet with a blend of helium appropriate for the planned depth.

What You Learn
Some of the skills you will learn:
- Advanced decompression dive planning
- Gas planning based on equivalent narcotic depths, nitrogen and helium absorption and elimination, CNS and OUT limits,
- Isobaric Counter diffusion, volume requirements, etc.
- Decompression gas choices
- Emergency and contingency planning (equipment failure, omitted decompression, etc)
- Management of multiple decompression/stage cylinders
- Emergency procedures (equipment failures, catastrophic gas loss, omitted decompression, navigational errors, injured/unconscious diver, etc)
- Equipment considerations, cylinder labelling, analysing trimix nitrox and mixes, and gas blending procedures
The Scuba Gear You'll Use
- Twin cylinders (minimum 12 litre/70 cubic feet each, with larger preferred) with isolator manifold
- Primary and secondary regulators, one with two metre/seven foot hose (approximately) for gas sharing, and one with SPG
- Stage/decompression cylinders with regulator, SPG, mounting hardware and proper labeling/markings. Two per diver will be required
- Backup decompression cylinders as appropriate and required for the environment
- BCD and harness – redundant buoyancy control is required (double bladder BCD or dry suit if suitable for weight of equipment worn)
- Depth gauge/computer and backup depth gauge/computer
- Timing device and backup timing device
- Trimix decompression information (tables/trimix computer) and backup decompression information
- Inflatable signal tube
- Reel
- Lift bag (bright yellow or per local community practice preferred)
- Dive knife / cutting device and backup slate, backup mask (optional)
- Compass, lights (optional)
- Drift kit (if drift decompressing)
Prerequisites
