What can I do as DSAT Tec Trimix Diver? 

For the extreme diver ready to further explore the world of technical deep diving, the gas of choice is trimix. It will cover training and procedures for Helium based diving to a maximum depth of 75 metres (during training). The Tec Trimix 75 takes you to the outer edges of technical deep diving, opening the door to pristine dive sites few divers – if any – ever see. 

After certification there are no depth limits, placed on how deep the diver can go, the key is the diver builds there experience gradually.

What do I need to start?  

Certified as a DSAT Tec 50 Diver or DSAT Tec Deep Diver or Tec 65 or equivalent (conditions apply)

Equipment Requirements?

• Double cylinders (minimum 12 l/70 cf each, with larger preferred) with isolator manifold or separate cylinders if using sidemount configuration.
• Primary and secondary regulators, one with two metre/seven foot hose (approx.) 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 students will use dry suits, they should be trained/experienced with their use in recreational and technical diving prior to using them for trimix training or diving.)
• Argon dry suit inflation or other inflation system as needed (students should not inflate dry suit with trimix)
• 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)
• Knife/cutting device and backup Slate Backup mask (optional)
• Compass Lights (optional)
• Drift kit (if drift decompressing) 

What will I do?

The DSAT Tec Trimix Diver course is intended to extend the depth range available to technical divers trained and qualified to use air, enriched air and oxygen for technical decompression dives beyond 50 metres/165 feet in open water. The Tec Trimix 75 course is intended for technical divers certified as DSAT Tec 50 (or qualifying certification from another training organization). The course extends their depth range capabilities by training them in the use of trimix (helium, oxygen and nitrogen).

Brand new training materials including diver workbook compliment the courses objective outlines, and includes 5 dives on top of the Tec 65 requirements.

What will I need?   

Tec Trimix Student Manual and the Tec Deep Diver Manual (need a few weeks before the start of the course to complete all knowledge reviews etc)
