The first thing your
instructor will want to do is go out with you for at least a couple of
dives, one down to around about 130ft. This will give them idea of
your general dive skills and anywhere you may need to brush up before you
start the course.
You'll learn to
make gas switch, extended no-decompression dives using air and enriched
air to 40 metres/130 feet. You'll also prepare for and respond to
foreseeable technical diving emergencies. Since it's part of the Tec Deep
Diver course, you DSAT Apprentice Tec Dive course training credits toward
