Technical and Exploration

TSD
The course prepares students for diving activities beyond the limits of “recreational sport diving”. These activities include depths to a maximum of 165 fsw/ 50 msw and involve multi-gas switches for decompression that will extend to a maximum of approximately 30 minutes. Full Oxygen and decompression tracking, dive planning, emergency protocol, equipment handling, and stress management skills, are covered in detail. This program is intended to serve as the building block of all of the ANDI Technical and Exploration programs.
