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.

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. 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. You will learn how to plan and execute at least five trimix decompression dives using various trimix blends, use decompression software to create custom dive tables and dive plans and make training dives as deep as 90 metres.

Where will it take me?

Trimix takes you to places very few people have ever gone before. In the past year Patrick has discovered three new wrecks off Durban and a World War 2 British Submarine. The ocean is the last remaining unexplored portion of the earth. Be the first!

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

  • Have a medical form signed by your physician
  • Be at least 18 years old


Your course fees are not buying you a certification. We do not include certification fees in our Technical Diving Course fees, for a very good reason: certification is not guaranteed. Technical diving, by its nature, is more complicated, and involves higher risk levels than recreational diving, and unlike some recreational diving courses, payment of fees does not imply automatic certification.

This does not mean that if, having completed the prescribed number of dives in the course outline that if you are unable to meet a required standard, you will be failed. We will do our utmost to get your skills and knowledge up to scratch, and if this means extra dives or academic sessions, then so be it.

If you are entering this course as a Tec 50 Diver, you must do all eight dives. Thus add the Tec Trimix 65 & Tec Trimix Courses together.

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