Diving: World's complete info and photos.
Diving is the action of man submerging into the sea, a lake, river or any other body of water, with the purpose of engaging in military or scientific research, commercial or recreational activities.
Types of Diving:
Self-contained diving :
When employing this technique the diver holds his breath without using any breathing apparatus and surfaces for new air. Breath-hold diving is divided into six main categories (not including the different varieties of each) which are very different from each other and which have different techniques and physical requirements.
Surface support diving :
The diver moves around connected to an air apparatus on the surface using the classical diving suit. This form of diving is used for scientific or commercial purposes. Even if the hose limits the diver’s movements, it allows for longer time underwater. Diver’s can use the classic Helmet-and-suit apparatus or the Hooka equipment.
Recreational diving :Defined as Self-Contained Diving, this form of diving is used for a purely recreational purpose, as opposed to a commercial one. It includes various modes such as, underwater hunting, underwater photography, orientation, collection of species, etc.
Adapted diving :
Adapted Diving is the combination of underwater activities in apnea or self-contained apparatus diving that is used by people with disabilities. They need a series of adjustments as to materials, techniques or logistics used in order to dive under the same secure circumstances as the standard individual. Under normal circumstances, evidently, people with disabilities would not be able to dive using the “self-contained” mode.
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 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 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. Depending on 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.
Technical diving (sometimes referred to as Tec diving) is a form of scuba diving that exceeds the scope (in terms of depth, bottom time and type of diving) of recreational diving (although the vast majority of technical divers dive for recreation and nothing else). Technical divers require advanced training, extensive experience, specialized equipment and often breathe breathing gases other than air or standard nitrox.
