Scuba diving is a common activity among individuals that enjoy underwater diving. Diving is an amazing experience – seeing the wonders of the ocean is something that cannot be explained by words or pictures. Diving is a great way to observe sea life in their natural habitat, visit a wreck of a decommissioned sea vessel or explore underwater caves to experience the depths and mystery that the ocean has to offer. Scuba diving is also used by professionals who are required to perform tasks underwater. These include civil engineering tasks such as in oil exploration, naval diving and salvaging of wrecks. Other specialist areas of diving include military diving, rescue operations as well as professional divers involved with the water itself such as underwater photographers and scientific divers.
The word SCUBA originally was an acronym for self contained underwater breathing apparatus, and involves scuba divers carrying their own source of breathing gas, which is usually compressed air, allowing greater freedom of movement. Scuba diving is advantageous as it allows the divers to stay underwater significantly longer than with breath-holding techniques used in snorkeling and free-diving. There is an extensive range of scuba diving equipment – the most basic include wetsuits, regulators, fins, masks, cylinders and a buoyancy compensator. There is other equipment available too such as torches, knives, cylinder valves, nozzles, adaptors, weight belts, pressure gauges, protective computer covers and dive watches. Before going for an actual dive, a scuba diver must first have the proper training as well as the right equipment in order to enjoy the diving experience best and stay safe under the water.
The most important gear is a diving mask, which allows the diver to see what there is to see under water. A diving mask is important because as you dive lower, the amount of pressure on your face increases. Fins are also important in diving, especially if you are going more than 30 feet in water depth. Fins will help enhance the diver’s thrust underwater. A buoyancy compensator is a vest that helps the diver come up to the water surface. Divers should also wear a wetsuit that serves as an insulator for the body. A regulator is essential for diving and is used to supply the diver with breathing air at a low level of pressure. It is also used to control the flow of air when needed. A breathing gas cylinder is obviously required which contains the divers’ needed air for survival and is normally strapped on the shoulder.
