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 metres/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 metres /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 metres/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 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 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)
