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

The PADI Tec 50 course will complete your training as an entry-level Tec diver, taking you past the limits of recreational diving.  During the course you’ll make actual decompression dives as deep as 50m/165feet and use EANx and/or oxygen for your decompression stops.  You will also use desk top decompression software to create custom dive tables and plan your dives.  Upon completion of the course you will be able to make technical decompression dives independently.  

Equipment required:

You’ll use your technical scuba equipment.

The PADI Tec 40 course is an introduction to technical diving and is the first subdivision of the full PADI Tec Deep Diver course and consists of four dives. Throughout the course you’ll learn how to use decompression software and dive computers to plan and make decompression dives with no more than 10 minutes of total decompression and not deeper than 40 metres/130ft.  You’ll also learn to use a single cylinder of decompression gas with up to 50% oxygen (EANx 50).  This training also credits towards the Tec 45 and Tec 50 courses.

Equipment required:

You’ll use your recreational scuba equipment, with some minor additions to enhance your ability to deal with Tec diving conditions.

 

Prerequisites for the Tec 45 course, you must be:

  • A PADI Advanced Open Water Diver (or hold a qualifying certification from another organization)
  • A PADI Rescue Diver (or hold a qualifying certification from another organization)
  • A PADI Enriched Air Diver (or hold a qualifying certification from another organization)
  • PADI Deep Diver (or hold aqualifying certification from another organization)
  • Have a minimum of 50 logged dives, of which at least:
              o 10 dives must be on enriched air
              o 12 dives must be deeper than 18 metres/60 feet
              o 6 dives must be deeper than 30 metres/100 feet
  • At least 18 years old
  • Have medical form signed by your

The PADI Tec 45 course picks up where PADI Tec 40 left off and will take your training as a Tec diver further and deeper. It is the second sub course in the full PADI Tec Diver course.  Throughout the course you will learn the skills, equipment and planning need to dive to a maximum of 45 metres/145 feet.  As well as the knowledge to plan and execute both single and repetitive decompression dives using a single stage cylinder of EANx to accelerate decompression stops.  You will also look at how to prepare for and respond to foreseeable technical diving emergencies and master the basic skills and procedures you’ll need as you move into deeper technical diving.

Equipment required:

You’ll use your recreational scuba equipment, with some minor additions to enhance your ability to deal with Tec diving conditions.
