Deep-sea diving is a form of underwater scuba diving where a diver uses a personal-comprised under

the sea respiration apparatus (scuba) to breathe in under the sea.[1] scuba diving courses

In contrast to other methods of plunging, which be dependent either on air-maintain or on air flow

motivated through the surface area, scuba divers bring their own source of respiration gas, typically

compressed oxygen,[2] enabling them higher flexibility of motion as compared to an aura series or

diver's umbilical and lengthier underwater strength than breathing-keep. Scuba products can be

available circuit, by which exhaled gasoline is expelled on the setting, or even a shut down or semi-

closed circuit rebreather, in which the respiration gasoline is scrubbed to eliminate co2, along with the

air employed is replenished from the availability of nourish gasoline before being re-breathed.

A scuba diver usually moves around underwater by using fins attached to the feet, but external

propulsion can be provided by a diver propulsion vehicle, or a sled pulled from the surface.
