Editing Scuba set (section)

===Back mount===
Back mounted scuba is straightforward, popular and for a single cylinder well balanced and easy to learn to use. There are several variations on the configuration which have been developed to improve convenience, safety, or suitability for use with multiple cylinders.

====Stabilizer jacket====
The most common configuration for recreational diving is the stabilizer jacket harness, in which a single cylinder, or occasionally twins, is strapped to the jacket style buoyancy compensator which is used as the harness. Some jacket style harnesses allow a bailout or decompression cylinder to be sling mounted from D-rings on the harness. A small [[bailout cylinder]] (pony cylinder) can also be strapped to the side of the main back-mounted cylinder.<ref name="Zeagle pony bands" /><ref name="AP pony bands" />

====Backplate and wing====

Another popular configuration is the [[backplate and wing]] arrangement, which uses a back inflation buoyancy compensator bladder sandwiched between a rigid backplate and the main gas cylinder or cylinders. This arrangement is particularly popular with twin or double cylinder sets, and can be used to carry larger sets of three or four cylinders and most rebreathers. Additional cylinders for [[Decompression (diving)|decompression]] can be sling mounted at the diver's sides.{{citation needed|date=December 2016}}

====Plain backpack====
It is also possible to use a plain backpack harness to support the set, either with a horse-collar buoyancy compensator, or without any buoyancy compensator. This was the standard arrangement before the introduction of the buoyancy compensator, and is still used by some recreational and professional divers when it suits the diving operation.{{citation needed|date=December 2016}}

====Bailout and safety harness====
Surface-supplied divers are generally required to carry an emergency gas supply, also known as a [[bailout set]], which is usually back-mounted open circuit scuba connected into the breathing gas supply system by connecting an interstage hose to the gas switching block, (or bailout block), mounted on the side of the helmet or full-face mask, or on the diver's harness where it can easily be reached, but is unlikely to be accidentally opened. Other mounting arrangements may be used for special circumstances.

====Integrated harness and storage/transport container====

The Mini B scuba system is an open circuit scuba set with an integral harness and soft transport/storage bag.<ref>invented by R.P.Hart{{citation needed|date=August 2024}}</ref> These units consist of a rucksack with a one size fits all harness, inside which is an air cell for buoyancy control, a horizontally mounted cylinder, and a regulator with primary and octopus demand valves, and a console with submersible pressure gauge and depth gauge, which protrude from the top of the unit when in use. Some military rebreathers such as the [[Interspiro DCSC]] and the Russian [[IDA71]] also store the breathing hoses inside the housing when not in use.<ref name="Larsson 2000" />
