Scuba diving is a form of underwater diving in which a diver uses a scuba set to breathe underwater for recreation, commercial or industrial reasons. Unlike early diving, which relied exclusively on air pumped from the surface, scuba divers carry their own source of breathing gas (usually compressed air), allowing them greater freedom than with an air line. Both surface supplied and scuba diving allow divers to stay underwater significantly longer than with breath-holding techniques as used in snorkelling and free-diving.
Basic equipment:
Scuba diving: Scuba BCD, tank, regulator, wetsuit, mask, swimfins, weight belt, torch. Snorkelling: diving mask, snorkel, swimfins.
