TDI Instructor programmes

from Basic Nitrox to Adv Trimix

We would recommend all instructor candidates complete the full range of TDI open water diver level courses or equivalent, before going onto Instructor levels. During training, Instructors will master the necessary discipline, the high degree of skill development required, and the academic and practical knowledge necessary to track and train groups of students in the “deep, dark, alien, hostile abyss” down to a maximum training depth of 100 meters.

Duration for Instructor level courses from Basic Nitrox through to Extended Range, are the same as the equivalent diver level courses. Based on the discretion of the Instructor trainer, one of two methods would be used to run the instructor programme. The candidates will either become involved in role playing, simulating common problems and worst case scenarios, or they will teach the appropriate diver level course with real students, under supervision of the instructor trainer.

The entry level  and  Adv. Trimix Instructor courses are a two part programme. Candidates must assist on at least two full Trimix courses before certification.
