Trimix 50
Description
The purpose of the Trimix 50 Diver Course is to develop the theoretical and practical skills of existing Tec 50 divers to enable them to safely use a limited range of trimix gases to dive within their current depth qualifications. You’ll extend your bottom time using trimix to a max depth limit to 50 metres/165 feet and learn to plan and execute repetitive decompression dives using a single stage/decompression cylinder. It puts you in a complete tec diving rig, which can be either backmount or sidemount. You’ll also make accelerated decompression dives using EANx or pure oxygen. This is a course where you’ll rise to the challenge and make the commitment to become a technical diver.
To enroll in the Trimix 45 course, you must:
-
Be a Tec 50 diver
-
Be a Rescue Diver
-
Have a minimum of 50 logged dives, with at least 12 dives on enriched air nitrox deeper than 18 metres/60 feet and 6 dives deeper than 30 metres/100 feet
-
Be 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 Deep Instructor.

Open circuit equipment - including, per diver, but is not limited to:
-
Double cylinders (minimum 12 l/70 cf each) with isolator manifold if backmounted. (Sidemount equipment may be used if the student has completed their Tec 45 or Tec 50 in Sidemount and the Instructor is a Sidemount Instructor with experience of teaching Sidemount diving at this level)
-
Primary and secondary regulators, one with two metre/seven foot hose (approx.) for gas sharing, and one with SPG
-
One Stage/decompression cylinder with regulator, SPG, mounting hardware and proper labelling/markings
-
BCD and harness – redundant buoyancy control is required (double bladder BCD or dry suit if suitable for weight of equipment worn)
-
Trimix multi-gas dive computer and backup depth gauge/computer
-
Exposure suit appropriate for environment and dive duration. (If students will
use dry suits, they should be trained and experienced in their use.
-
Argon dry suit inflation or other inflation system as needed (students should not inflate dry suit with trimix)
-
Weight system
-
Surface Marker Buoy – as appropriate for the local environment
-
Reel
-
Knife/cutting device and backup
-
Slate
-
Backup mask
-
Compass
-
Lights
Specialty equipment – must be available for all divers to use:
-
Helium analyzer – strongly recommended
-
Oxygen Analyzer
-
Computer with suitable decompression planning software
