This scuba diving course is also offered by another agency, PADI tec sidemount diving.
My first courses were technical sidemount, and sidemount. Sidemount diving, which is the name of the course, involves placing your tank into your hands. My hands and knuckles were covered with cuts by the end. It is possible to remove the tanks from the clips and lay them out front of you Superman-style. The afternoon dive went much better after I made some adjustments to our harness. I was now comfortable with my harness, and was 'Superman'-ing with the tanks. Sidemount allows for an extraordinary level of freedom. Matt had set up obstacles courses. Soon we were flying around them, with tanks out front, barrel rolling and even swimming upside-down.
There are many great readings about technical diving. Some are stories of personal experiences and adventures in technical diving that are definitely worth reading. Some of the greatest books for sure are:
Backmounted doubles were created in response to problems with single orifice and backmounted independences. Independents consist of two cylinders, each with its own regulator. The diver could only use one cylinder if a first stage failed. Single orifice duals consisted of two cylinders linked by a valve. One regulator was used for the first stage. The gas would not be released if the first stage failed due to a failure of one orifice doubles. Both of these problems have been eliminated by today's isolated manifold duplicates. Each cylinder is capable of being worked separately, but the diver can use one regulator to allow him or her to inhale gas directly from both cylinders. This type of doubles is usually held together using metal bands. Additionally, the valves are linked by an isolation manifold which allows the two to be separated as needed. Backmounted doubles diving looks similar to regular single cylinder backmounts, but it has a profile that is vertically identical.
At first, technical diving was not something that interested me. I can clearly recall chuckling to my self at the Tec divers I observed, and wondering why anyone would want to have more equipment under water. I love the feeling of freedom and closeness to nature that can envelope you in "the quiet world". Tom was a respected teacher who I felt it was important to share my experience in Tec courses with.

To make dives beyond 130ft, decompression divers will add Helium to the cylinders. Then they can explore the realm of the uncommon. Their experiences at wrecks and reefs are often less frequent than those of astronauts who visit the moon.
Sidemount cylinder mounting was first used for cave diving. It has since become more popular in technical diving. They take the dual cylinders apart, one for each, and place them on either side. The diver can't breathe from either cylinder if the regulator fails, but this allows for easier access to valves. Sidemount diving gives the diver an increased horizontal profile and a smaller vertical profile.
If you are not ready to dive locally, but wish to support your local dive center, you can complete eLearning courses and coursework close to home. You can then travel to complete your training dives. Ask your local PADI Dive Center for a referral.
International Training, the parent organization for Scuba Diving International (SDI) and Technical Diving International (TDI) offers both SDI and TDI versions of their Sidemount Diver course. Both courses are very similar. Both use the same learning materials (which, by the way, we wrote). So what’s the difference?
Technical divers explore reefs and wrecks at depths below the 40 meter/130-foot recreational limit. With specialized training, they can explore underwater caves and other places well beyond the reach of mainstream recreational diving.
If you're not yet ready to try local diving but would like to support your local dive store, you can do your eLearning at home and then go on to your training dives abroad. Request a referral from your local PADI Dive Center.
Sidemount PCB can answer your questions regarding medical fitness to dive.
New gear means new techniques. Diving sidemount, if it's easy, require some new skills (easy to learn).
