about sidemount
Sidemount diving was invented in the sixties, and has steadily been gaining popularity over the decades.

Today it is promoted as a valid alternative to twin set diving, and remains the industry standard configuration when it comes to operating in tight spaces such as cave systems and wrecks.
FLEXIBILITY
Sidemount diving offers some benefits in the flexibility of equipment. Cylinders suitable for sidemount diving are usually freely available for rental, unlike manifolded twin sets for back mounted use, which allows the traveller to conduct technical or overhead environment dives without having to source twin cylinder sets.

When diving in remote locations, the transportation of single diving cylinders, especially by hand, may be less physically taxing. Sidemount harnesses can be lighter and less bulky than back mounted alternatives – allowing for easier and cheaper air travel.
