The sidemount rig was originally invented for cave diving as it allows the diver to pass thru cracks and restrictions (tiny holes) easier than the classic back mount rig.
Technical diving was something I didn't initially like to do. I clearly remember chuckling at the Tec divers that I saw and wondering why anyone would want more equipment underwater. The feeling of being close to nature and the freedom it can give you is something I love. Tom was an inspiring teacher and it seemed right to try, as I was working at a dive shop that offered Tec courses.
‘Caverns Measureless to Men’ by Sheck Exley, one of the pioneers of cave diving in Florida, USA. He also wore ‘Basic Cave Diving: A Blueprint for Survival’ which studies many cave diving accidents.
Sidemount diving has become very popular in open water. It is more comfortable than having a tank on the back and allows you to have more fun.
Rebreathers can increase your diving skills by using smaller cylinders. This can significantly increase the dive duration, especially when used for deeper dives. Rebreathers can be mounted sideways or back. It all depends on how they are configured.
Sidemount diving provides an independent air source. Two tanks are used, each with their own regulators and first stage, SPG. This makes it much safer and gives little air-hogs (like me) a lot more oxygen. Sidemount's tanks can be easily accessed from the surface. There is no pressure on the back.
One of the big risks for a technical diver is decompression sickness. It occurs when nitrogen gas cannot exit the body thru respiration on ascent as the ambient pressure decreases. Therefore stops have to be executed on ascent in order to avoid a pressure difference too big so nitrogen bubbles can be formed. Buoyancy control is very important to control the stops on ascent and increase efficiency for off-gassing of nitrogen. Another important skill is proper breathing which makes metabolism efficient. Trim, which we call a proper tech diving position such as horizontal with a slight arch in the back, looking forward and knees at a 90 degree angle with fins pointing back. Trim prevents stirring up sediments on the bottom as well as most efficient movement in the water. And of course proper finning techniques to avoid overexertion are mandatory to make a diver achieve maximum performance. Now you might say, we want to have fun when we go diving and not be a machine.

Sidemount diving is a form of sidemount diving that originated in cave diving but has been incorporated into recreational and non-overhead diving over the years. Simply put, your tanks will be worn on your side instead of being attached to your back. The tanks attach to a Sidemount BCD with clips or bungee chords, allowing for maximum flexibility. It was this flexibility that cave divers used to be able to lift their tanks from the bottom underwater, making it easier to pass through tight spaces.

Scuba diving sidemount is becoming more popular than ever in open water. You are more streamlined than having to carry a tank around your back.
The depth range of oxygen rebreathers (simple closed circuit) is limited to approximately 6 m, beyond which the risk of acute oxygen toxicity rises to unacceptable levels very quickly.
