Scuba diving is a mode of underwater diving in which the scuba diver uses a self-contained underwater breathing apparatus called scubas. The apparatus is completely independent of surface supply of oxygen needed to breathe underwater. It is different from other modes of diving in which divers solely rely on breath hold or on breathing supplied under pressure from the surface. In scuba a person carries their own source of air supply. To learn about scuba diving Seagrove is worth checking out.
It started in mid-20th century with two basic types. The open circuit and closed circuit. The open circuit one the divers exhales is vented directly in the water. For the closed circuit the exhaled air is recycled by addition of oxygen and then recirculated back to be used by the diver.
Scubas are personally and professionally applied in different fields. It is mostly done as a recreational or leisure activity. It is mostly done for enjoyment. Complicated underwater tasks are usually performed by hired professional divers. The application of this form of diving in the military is also common. Millitaries use it for infiltration, placement of mines and direct combat.
There is also a field of study that concerns underwater environment. This includes such as underwater photography and videography. These people research and document the underwater world. This also include scientific diving, marine biology, geology, hydrology and underwater archaeology.It is also a full time profession. Professional divers provide lessons in this activity.
The equipment to be used is governed by legal rules. Scubas are the most suitable in cases where mobility is needed underwater. Surface-supplied systems are more preferable in cases where the risks involved are very high. Individual training levels can determine how deep one can dive during this activity. Different countries also have different rules governing the activity.
A scuba is the equipment used in this exercise. It is a breathing apparatus that is designed to be self-contained. Divers usually transport these apparatus on their backs. To allow inflation of the lungs, inhaled breath must balance with the surrounding. A half mask is a requirement for all divers. The mask covers the eyes and the nose of a diver. The mouthpiece supplies breathing gas from scubas. The masks often allow the diver to breathe through the nose. It does not only allow breathing but also covers eyes, mouth, and the nose of a diver.
The diver also requires diving gas. Which is usually in a mixture of oxygen, nitrogen and trace gases. To dive safely divers need to maintain control over their rate of ascent and descent in the water. This also helps them to be able to maintain a constant depth in the mid water.
There are some risks involved too. This are caused mainly by poor gas management, poor buoyancy control, entrapment, equipment misuse, pre-existing health problems, and rough water conditions in the sea . Although some risks may be unforeseen. When one wants to engage in this activity, they should employ a professional to train and teach them before doing so.
