Scuba diving is defined by the use of underwater diving that is extended by the use of a self-contained breathing apparatus. 'Scuba' is actually an acronym for “Self Contained Underwater Breathing Apparatus.” Scuba equipment usually consists of a tank of breathable air, a tube leading to the mouth piece, fins worn on the feet to propel the diver, a diving suit, and sometimes a DPV (diver propulsion vehicle) or 'scooter' used to move the diver around quickly.
