Inspired by Sanctum 3D movie,I've decided to start the topic about scuba diving and everything that concerns it.and by the way are there any divers?

Scuba diving ("SCUBA" originally being an acronym for self contained underwater breathing apparatus, now widely considered a word in its own right) is a form of underwater diving in which a diver uses a scuba set to breathe underwater.



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.

According to the purpose of the dive, a diver usually moves underwater by swimfins attached to the feet, but external propulsion can come from an underwater vehicle, or a sled pulled from the surface.

The pics are amazing, and I'm sure, it is a lot of fun to scuba dive, but I guess it's kind of a phobia for me, cause I cant imagine being with limited amount of oxygen somewhere deep in the water
