PADI Tec Trimix 65

If you’re into technical diving then you know that to extend your depth range you need to use trimix – a blend of helium, oxygen and nitrogen. The Tec Trimix 65 course introduces you to using trimix down to a maximum depth of 65 metres/210 feet. There are advantages to using three gases, but you need to know how to do it right. Earning the Tec Trimix 65 certification makes deeper exploration a reality.

You’re qualified to enroll in the Tec Trimix 65 course, if you:

  • Are a PADI Tec 50 diver
  • Have a minimum of 100 logged dives
  • Are at least 18 years old
  • Have a Medical Statement signed by a physician within the last 12 months

Note that qualifying certifications from other diver training organizations may apply – ask your Tec Trimix Instructor.
