DSAT TEC TRIMIX


DSAT TEC Trimix Technical Diving Courses

For the extreme technical diver ready to further explore the world of technical deep diving, the gas of choice is Trimix – a blend of oxygen, helium and nitrogen. Nitrogen narcosis can be avoided by replacing nitrogen with helium. Helium is not as narcotic as nitrogen. By decreasing the percentage of oxygen in the mix, the diver can dive deeper without a danger of oxygen toxicity. Trimix diving and training is very advanced technical diving and the individual should have good knowledge and broad experience about diving generally, having been diving with previously with nitrox and decompression gas usage

The PADI DSAT TEC Trimix Technical Diving Courses take 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

TEC trimix DiverThe 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

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 a two metre 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)
