TDI Trimix Diver

TDI Trimix Diver

advanced trimix diverAs your knowledge, skills, abilities and motivation to explore grows you will find that you may want to dive deeper, maybe 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; The TDI Trimix Diver course shows how to minimize the effects of narcosis by adding helium to offset the nitrogen in your breathing gas. To breathe underwater a diver must be supplied air at a pressure equal to that of the water surrounding the diver. However there is an upper limit of oxygen pressure above which the oxygen becomes biochemically toxic. Therefore, it is necessary to include something to dilute the oxygen in a diver’s breathing gas, for this Helium is used and forms part of the diving gas known as Trimix. 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 feet with a blend of helium appropriate for the planned depth. The course covers topics and skills like:

  1. Dive team planning
  2. Gas matching
  3. Cylinder labeling
  4. Surface marker deployment
  5. Equipment configuration
  6. Thermal protection options

As a TDI Instructor Trainer Facility Waterfront Scuba can teach all off the TDI Technical Diving programmes, courses are taught by divers who regularly undertake technical dives as part of their own diving season. So you are taught by instructors who actually go diving, not by people who just teach.

Drills and skills can be first mastered in our 6 metre deep training pool before moving on to the open water elements of the course.
