SCUBADIVING

Scubadiving is using self-contained breathing equipment to stay underwater for periods of time greater than human breath-holding ability allows.

The scubadiver carries all equipment necessary for diving and is not reliant upon equipment elsewhere (e.g. on the surface) to supply breathing gas or other support during the dive.

The diver swims underwater using fins attached to the feet. Some divers also move around with the assistance of a DPV (Diver Propulsion Vehicle, commonly referred to as a "scooter", or by using surface-tethered devices called sleds, which are pulled by a boat.

However, rebreathers (both semi-closed circuit and closed circuit) are also self-contained systems (as opposed to surface-supplied systems) and could be classed as SCUBA. The term SCUBA arose during World War II and originally referred to USA combat frogmen's oxygen rebreathers, developed by Dr. Christian Lambertsen for underwater warfare.

You can scuba dive in most places where the water is sufficiently deep. So you can choose from the ocean, lakes, mines, rivers, caves and anywhere else appropriate.

Tip! Once you've tried scuba diving, you probably won't need anyone else to answer this question for you. Some people simply enjoy the sport and continue diving.
