What is Scuba Diving?

is a form of underwater diving in which a diver uses a self contained underwater breathing apparatus to breathe underwater.

Unlike other modes of diving, which rely either on breath-hold or on air pumped from the surface, scuba divers carry their own source of breathing gas, (usually compressed air), allowing them greater freedom of movement than with an air lineor diver's umbilical and longer underwater endurance than breath-hold. Scuba equipment may be open circuit, in which exhaled gas is exhausted to the surroundings, or closed or semi-closed circuit, in which the breathing gas is scrubbed to remove carbon dioxide, and the oxygen used is replenished from a supply of feed gas before being re-breathed.

A scuba diver usually moves around underwater by using swimfins attached to the feet, but external propulsion can be provided by a diver propulsion vehicle, or a sled pulled from the surface.

History of Scuba Diving?

The first commercially successful scuba sets were the Aqualung twin hose open-circuit units developed by Emile Gagnan and Jacques-Yves Cousteau, in which compressed air carried in back mounted cylinders is inhaled through a demand regulator and then exhaled into the water adjacent to the tank.[3] The single hose two stage scuba regulators of today trace their origins to Australia, where Ted Eldred developed the first example of this type of regulator, known as the Porpoise, which was developed because patents protected the Aqualung's twin hose design. The single hose regulator separates the cylinder from the demand valve, giving the diver air at the pressure at their mouth, not that at the top of the cylinder.

The open circuit compressed air systems were developed after Cousteau had a number of incidents of oxygen toxicity using an oxygenrebreather, in which exhaled oxygen is passed through an absorbent chemical to remove carbon dioxide before being breathed again. Modern versions of rebreather systems (both semi-closed circuit and closed circuit) are available, and form the second main type of scuba unit, mostly used for technical and military diving

Scuba Diver Training and certification:

Recreational scuba diving does not have a centralized certifying or regulatory agency, and is mostly self regulated. There are, however, several large diving organizations that train and certify divers and dive instructors, and many diving related sales and rental outlets require proof of diver certification from one of these organizations prior to selling or renting certain diving products or services.
