TDI Trimix Diver


Why become a TDI Trimix diver?

As your motivation to explore progresses you will find that you may want to go deeper to dive that wreck that is part of history or that cave system that you have read so much about. One of the major limiting factors of going deeper is narcosis; TDIs Trimix Diver course shows how to minimize the effects of narcosis by adding helium to offset the nitrogen in your breathing gas.


What will I do?

While taking the Trimix Diver course your TDI Instructor will teach you how to plan and execute dives utilizing as little as 18 percent oxygen and diving to maximum depth of 60 m/200 feet with a blend of helium appropriate for the planned depth. The course covers topics and skills such as

  • Dive team planning
  • Gas matching

  • Cylinder labeling

  • Surface marker deployment

  • Equipment configuration

  • Thermal protection options


What do I need to start?

  • Be a minimum age of eighteen 18

  • Have a minimum certification as a TDI Advanced Nitrox Diver and Decompression Procedures Diver (or equivalent).

  • Show proof of a minimum of 100 logged dives.


What does the course include?

For the price of $995 you will complete 4 dives with a maximum depth of 60 metres, manual and certification. 


What do I need to provide?

Technical diving is generally very equipment involved, your TDI Instructor will go over the specific requirements at the beggining of your course and what pieces of equipment you will need to supply. Gas blends and cylinders are not included in the cost of the course.
