Sidemount diving presents divers with a different approach to equipment configuration and diving techniques to master. Its benefits include ease of streamlining, easier equipment transport, versatility, increased gas supply, accessibility and is particularly useful in tight spaces (like cave and cavern diving).
The difference with Tec Sidemount diving as opposed to the recreational sidemount diving is that it now includes the use of two or more cylinders for extended dive times going beyond that of the recreational course.
It also offers an alternative to twin cylinder use traditionally employed in Tec 40, 45 and 50 diver practice. Course duration is three days.
