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.
Each PADI Specialty you take will help you get closer to becoming a Master Scuba Diver(tm).
Sidemount regulators can also be used. One regulator will be on a long length hose, while one regulator will be on a shorter one with a necklace. Sidemount regs have a marked design, which makes it easy to identify the tank you are in. This also included a swivel connector for my short-hose regulator. Two SPGs will be provided - one for each stage.
Sidemount Diver Specialty can count towards Advanced Open Water Diver certification. Talk to your instructor about earning credit.

Because single orifice duals and backmounted independencies are less common today, backmounted doubles became popular. Independents have two cylinders strapped to the back of one another with independent regulators. If the 1st stage failed, the diver would only need one cylinder. Single orifice twos were two cylinders that were connected with a regulator and a valve. A failure on the first stage would result in gas loss. Both problems are solved by the isolation manifold doubles that are used today. Each cylinder may be used independently. But, divers can also use the same regulator to breathe gas from both. These doubles are often held together by metal bands. If necessary, the valves can be connected to an isolation manifold. Backmounted doubles diving has a similar profile to regular single-cylinder dives. However, the profile is vertically identical.
Scuba diving requires a minimum level of health and fitness. Chronic health conditions, certain medications and/or recent surgery may require you to get written approval from a physician before diving.
There are three components to certification: skill practice, knowledge development and open water diving. All three parts can be completed locally or on vacation, or you can split them.

And then there are the rebreathers…a rebreather is a machine that recycles exhaled gas and is the preferred method for ‘very’ deep dives in order to use the gas carried more efficiently. In this case the exhaled gas is going thru a canister filled with a chemical which is called Sofnolime or scrubber to remove CO2 from the breathing loop and the remaining gas will be inhaled again by the diver. Metabolised oxygen is replaced into the loop to keep the oxygen content in the divers’ body at the desired pressure.

Although I'm still learning, Sidemount diving is something I feel confident in. I have done 20 Sidemount dives and I can proudly say I'm a Sidemount diver.
To begin a technical diving course, you must have completed the following prerequisites: a PADI Advanced Open Water Diver certificate or equivalent, a PADI Enriched Air Diver certificate or equivalent, and a PADI Deep Diver certificate or proof of at least 10 dives to 30 metres/100 feet.
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.
2-3 hours
Even with small cylinders, you can usually dive for 2-3 hours (rebreathers typically have two 2/3l cylinders or one 3/5l cylinder).
