SCUBA is an acronym for Self Contained Underwater Breathing Apparatus. It has become acceptable to use terms such as Scuba Diving, Scuba Equipment, Scuba Diver, Scuba Gear etc.

Scuba Diving

Scuba diving is swimming underwater while carrying a source of breathing gas (usually compressed air), then the scuba diver is able to stay underwater a lot longer than using with the breath-holding techniques used in snorkeling and free-diving, and is not hindered by air lines to a remote air source. The scuba diver typically swims underwater by using scuba diving flippers attached to their feet. However, some divers also move around with the assistance of a DPV (diver propulsion vehicle), commonly called a "scooter", or by using surface-tethered devices called sleds pulled by a boat.

History Of Scuba Diving

Recreational scuba diving grew from related activities such as snorkelling and underwater hunting. Recreational underwater excursions were limited by the amount of breath a person could hold. This was changed by the invention of the aqualung in 1943 by Jacques-Yves Cousteau and its development over subsequent years led to a revolution in recreational diving.

As the sport became more popular, manufacturers became aware of the potential market, Scuba equipment began to appear that was easy to use, and more affordable and reliable.


Further developments in technology have reduced the cost of training and diving. Scuba-diving has become a popular leisure activity, and many diving locations have some form of dive shop presence that can offer air fills, equipment and training.

In tropical and sub-tropical parts of the world, there is a large market in 'holiday divers'; people who train and dive while on holiday, but rarely dive close to home.

Generally, recreational diving depths are limited to a maximum of between 30 and 40 meters (100 and 130 feet), beyond which a variety of safety issues make it unsafe to dive using recreation diving equipment and practices, and specialized training and equipment for technical diving are needed.
