Tec Trimix Diver

The Tec Trimix Diver Course with REEF DIVERS

For the extreme 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 (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 metres/300feet

The 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
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)

The Learning Materials You'll Need

The Tec Trimix Diver Crew-Pak includes all required materials, including: 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.

Prerequisites

You must:

Be a PADI Rescue Diver (or hold a qualifying certification from another organization and having proof of CPR and first aid training with the previous two years)
Be certified as a Tec 50 or Tec Trimix 65 (or those holding a qualifying certification from another training organization)
Be at least 18 years old
Have logged at least 150 dives
Have a medical form signed by your physician
