TEC TRIMIX DIVER For the prepared diver ready to further explore the world of technical deep diving

The Tec Trimix Diver Course with Blue Planet

For the prepared and experienced diver ready to further explore the world of technical deep diving, the gas of choice is trimix – 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 – if any – 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, 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 Tec 50 or 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).

You will

• 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
• Use decompression software to create custom dive tables and dive plans
• Make training dives as deep as 90 meters/~300 feet

The Scuba Gear You'll Use

• Sidemount cylinders (minimum 12 liter/70 cubic feet each, with larger preferred)
• Primary and secondary regulators, one with two meter/seven foot hose (approximately) for gas sharing, each with an 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
• Sidemount harness with redundant buoyancy cell.
• 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.)
• Weight system
• Jon line (if needed for current diving environments)
• Inflatable signal tubes
• Reels
• Lift bag (bright yellow or per local community practice preferred)
• Cutting devices and backup slate, backup mask
• Compass, dive lights
• Drift kit (if drift decompressing)

The Learning Materials You'll Need

The Tec Trimix Diver Crew-Pak includes all required materials: manual, deep stop calculation table, trimix decal and emergency procedures slate.

Topics covered include:

• Trimix diving depth ranges
• Exposure planning
• Selecting a mix
• Argon inflation systems
• Handling three or four decompression cylinders
• Decompression models
• Emergency procedures
• Face masks and multi-gas computers
