Targets
The 'T 3' course aims to complete the training started with the 'T 2' expanding the theoretical and practical knowledge and experience, to dive at a maximum depth of 80 meters, using Tri-mix and multiple decompression mixtures. The structure of the program is the same of the previous courses: theory, confined water sessions and open water dives. The 'T 3' program is mainly focused on decompression theory and procedures, to extend the range of the dives. With the positively conclusion of the course the diver will be able to plan and dive till 80 meters depth.
STDA fixes the 80mts depth as limit for the OC diving and considers rebreathers the logical diving equipment for deep dives, just below 60 mts depth.
Prerequisites
- be certified 'T 2' or equivalent
- medical certificate not older than one year; recommended PFO examination (Patent foramen ovale); non smoker
- minimum age: 21 years old
- documented experience of at least 100 dives, 40 with decompression
Before the course start, the instructor could ask to do a open circuit dive to evaluate the level of training of the candidate.
