TDI Advanced Trimix

Safely utilize Trimix to maximum depth of 330fsw/100msw.

This course provides the training required to competently and safely utilize breathing gases containing Helium for dives that require staged decompression, utilizing Nitrox and/or Oxygen mixtures during decompression to a maximum depth of 330fsw/100msw.

This new adventure promises challenges and excitement whilst calling upon all of your previously learnt skills, knowledge and experience. Mixed gas diving, like all decompression diving, results in a "virtual overhead" environment similar to that experienced by cave divers, thus requiring techniques and equipment back up. Your TDI Instructor will acquaint you with the necessary procedures and techniques whilst demonstrating the proper attitude required at this level.

By the time you enroll in this course you will have been indoctrinated in both the physics and physiology of diving. This course will review all these subjects and further enhance the role that Helium plays in our safe diving process. You will be expected to learn techniques of gas use solve simple math problems and be responsible for your physical fitness and mental preparedness.

This course is well suited to be undertaken in conjunction with the TDI Advanced Gas Blender course.
