Objectives of the Tec Trimix 65 course.
The course extends your depth range capabilities up to 65 meters by training you to use trimix (a blend of helium, oxygen and nitrogen).
You will
- 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 65 meters/210 feet
Trimix equipment used for the course
- Double cylinders (minimum 12 litre/70 cubic feet each, with larger preferred) with isolator manifold
- Primary and secondary regulators, one with two meters/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 dry suit inflation or other inflation system as needed
- Weight system (if needed)
- Jon line (if needed for current diving environments)
- 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)
