Scuba diving is a kind of diving where the divider or the scuba diver utilizes a breathing apparatus that is self-contained. The breathing apparatus is completely independent of the surface supply so that the diver can breathe even when he or she is under the water. Another type of diving usually relies on the breath hold or the breathing that is supplied under the pressure that is exerted on the surface. The scuba diver carries his or her breathing gas even when under the water. The breathing gas s comprised of the gas that has been compressed, and therefore the scuba diver can have the freedom of movement. The breathing gas is more comfortable compared to the airline or the diver's umbilical cord that the other divers use. This keeps the diver inside the water for a longer period compared to other divers who use the breath hold. The open circuit scuba systems discharge the gas into the environment when the gas is exhaled. The scuba system has one or more diving cylinders that have the breathing gas supplied at a very high pressure that is mainly supplied through a diving regulator.
