Tec Trimix Diver
For the extreme diver ready to further explore the world of technical deep diving, the gas of choice is trimix â€“ a blend of oxygen, helium and nitrogen.
The PADI Tec Trimix Diver course takes you to the outer edges of technical deep diving, opening the door to pristine dive sites few divers â€“ if any â€“ ever see.
What You Learn
The PADI Tec Trimix Diver course is intended to extend the depth range of technical divers already trained and qualified to use air,Â enriched airÂ and oxygen for technical decompression dives beyond 50 metres/165 feet. Diving with trimix is the outer edge of tec diving â€“ the maximum depth for using this technology has yet to be defined.
This course is forÂ Tec 50Â orÂ Tec Trimix 65Â (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).
â€˘Â Plan and execute between three to eight dives (depending upon whether you enter the course as a Tec 50 diver or Tec Trimix 65 diver) using EANX and trimix blends
â€˘Â Use decompression software to create custom dive tables and dive plans
â€˘Â Make training dives as deep asÂ 90 metres/300feet
The Scuba Gear You’ll Use
- DoubleÂ cylindersÂ (minimum 12 litre/70 cubic feetÂ each, with larger preferred) with isolator manifold
- Primary and secondaryÂ regulators, one with two metre/seven foot hose (approximately) for gas sharing, and one with SPG
- Stage/decompressionÂ cylindersÂ withÂ regulator, SPG, mounting hardware and proper labeling/markings. Two per diver will be required
- Backup decompressionÂ cylindersÂ as appropriate and required for the environment
- BCDÂ and harness â€“ redundant buoyancy control is required (double bladder BCD orÂ dry suitÂ if suitable for weight of equipment worn)
- Depth gauge/computerÂ and backup depth gauge/computer
- Timing deviceÂ and backup timing device
- Trimix decompression information (tables/trimix computer) and backup decompression information
- Exposure suitÂ appropriate for environment and dive duration. (If you use aÂ dry suit, you should be trained/experienced with its use in recreational and technical diving prior to using it for trimix training or diving.)
- ArgonÂ dry suitÂ inflation or other inflation system as needed
- Weight systemÂ (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 deviceÂ and backup slate, backupÂ maskÂ (optional)
- Compass, lights (optional)
- Drift kit (if drift decompressing)
