How To Become A Sidemount Technical Scuba Diver Guide

The advantages of Sidemount diving are an additional independent air source as you are diving with two tanks each with a first stage, SPG, and regulator. This makes it a lot safer and gives little air-hogs like myself a whole lot more air. I also found diving with Sidemount to be incredibly comfortable because you can easily don tanks on the surface and there is no pressure on your back.

Skills (specific): Throughout tech programs, the dive skills specific to that category are practiced until they become flawless. Line skills and navigation are perfected for overhead diving. Decompression divers can execute stops and manage gas without blinking an ear. Rebreather divers take great care in building, testing and disassembling their equipment to ensure its optimal functionality. The first level of certification lays the foundation for each course, with further training as necessary. Each step takes you deeper, or makes these skills more difficult. It is a way to become a better diver.

Divers who decompression dive use oxygen mixtures of every kind to prolong their time on the seafloor looking for wrecks and corals. The sport diver might only get two dives at 100ft, but a decompression diver can cruise for up to 60 minutes and still get the best bang for their buck.

Consider taking the Tec Sidemount Diver Course. You'll gain additional skills related to tec sidemount diving, such as switching deco cylinders or staging.

Although we can teach the SDI course if specifically requested, by default we offer the TDI one. It is possible to take this as a standalone program; however, our students generally combine this with our Apprentice Cave Diver course.

Backmounted doubles came into use in part because of the problems with backmounted independents and single orifice doubles, neither of which are as common in modern diving. Independents are two cylinders strapped to one’s back with independent regulators on each one. If a 1st stage was to fail the diver was down to one cylinder. Single orifice doubles were two cylinders linked together with a valve, and one 1st stage regulator. If a first stage failed on a single orifice doubles set all the gas would be lost. The isolated manifold doubles used today eliminate both of those problems. Each cylinder can be worked independently, but the diver can also breathe gas from both cylinders out of one regulator. This form of doubles is typically held together with metal bands and the valves are linked with an isolation manifold, allowing the two to be separate if needed. Backmounted doubles diving is similar to regular single cylinder backmount, offering a profile that is vertically the same.
