PADI TecRec - Tec 65 Trimix Course

 The Tec Trimix 65 course opens up the advantages of trimix diving, and upon completion divers are able 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.  This can be done to a maximum of 65m/210feet.  The course extends your depth range capabilities by training you to use trimix (a blend of helium, oxygen and nitrogen).During the course you will plan and execute at least 5 trimix decompression dives using different trimix blends, the training dives will be made to depths of 65m/210feet.  You will also use decompression software to create custom dive tables and plan dives.  Throughout the course the following topics will be covered: 

    * 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.

Equipment Required:

  • 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)

Prerequisites for the Trimix 65 course, 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 hold a qualifying certification from another organization)
  • Be at least 18 years old
  • Have logged at least 100 dives
  • Have a medical form signed by your physician
