The Tec Trimix 65 Course
This course opens up the advantages of trimix to the diver and divers are qualified to make multi-stop decompression dives that employ EANx and oxygen for accelerated decompression and any trimix with an oxygen content of 18% or more.
They can dive to a maximum depth of 65 meters/ 210 feet.
What you'll learn
The PADI Tec Trimix 65 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 meters / 165 feet.
This course is for Tec 50 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 dives using EANx and trimix blends
- Use decompression software to create custom dive tables and dive plans
- Make training dives as deep as 65 meters/ 210 feet
Scuba gear you'll use
- Double cylinders (minimum 12 litre/70 cubic feet each, with larger preferred) with isolator manifold
- Primary and secondary regulators, one with 2 meter/ 7-foot hose (approximately) for gas sharing and one with a 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
- 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)
