Objectives of the Tec Trimix course
The PADI Tec Trimix Diver course is intended to extend the depth range of technical divers already trained and qualified to use air, enriched air and oxygen for technical decompression dives beyond 50 metres/165 feet. Diving with trimix is the outer edge of tec diving – the maximum depth for using this technology has yet to be defined.
This course is for PADI Tec 50 or PADI Tec Trimix 65 divers (or those holding a qualifying certification from another training organization). The course extends your depth range capabilities by training you to use trimix (a blend of helium, oxygen and nitrogen).
- Plan and execute at least five trimix decompression dives using various trimix blends
- Use decompression software to create custom dive tables and dive plans
- Make training dives as deep as 75 metres/245 feet
Tec Trimix equipment used
- Double 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
- Exposure suit appropriate for environment and dive duration. (If you use a dry suit, you should be trained/experienced with its use in recreational and technical diving prior to using it for trimix training or diving.)
- Argon drysuit inflation or other inflation system as needed
- Weight system (if needed)
- Jon line (if needed for current diving environments)
- Inflatable signal tube
- 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)
