Scuba diving is an example of diving where the diver uses a breathing apparatus that could be self-contained. The breathing apparatus is usually independent, and it allows the dicer to breathe even when he or she is under the water. Unlike scuba divers, other types of divers use the breath hold or make use of the gas that is supplied from the surface of the water. The scuba diver carries his or her breathing gas even when he or she is under the water, and the cylinder is what supplies the oxygen to him, or her gas is usually compressed and therefore the gas is sufficient for the diver to move around the water. The gas that the diver owns is carried at the back. It is more convenient compared to the airline or the divers umbilical cord that other divers use from the surface of the water. This can keep the scuba diver in the water for a long period without the gas being exhausted. There is a system through which the gas that the diver exhales is emitted to the environment. This is mainly done through the open circuit systems discharge.
