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.
There are two basic types of scubas which were introduced in mid-20th century. These types are the open circuit and the closed circuit. Exhaled air of divers in an open circuit is directly vented into the water. In cases of a closed circuit, exhaled air is recycled. This is done by adding oxygen then circulated the air back to the diver.
Scuba diving has been used in so many different fields, that is, in both professional and personal application. Many people use it for leisure and some as a recreational activity. Generally it is for enjoyment. In tasks involving going underwater, professional divers are usually called upon. In the military this mode of diving also finds use in direct combat, placement of mines and infiltration.
There is a field of study that involves underwater environment, including underwater videography and photography. They are the ones that carry out researches and documentary of underwater world. It sometimes includes marine biology, hydrology scientific diving and underwater archeology. It is also known to be a full time profession. Those professional divers give lessons to students.
The equipment used is subject to certain limits and legal constraints. Scubas are suitable for use when there is need for large range of movement and mobility. In commercial applications where there are high risks, surface-supplied systems should be used. There are rules given in some countries that govern how deep the divers can dive. However, in some countries, how well-trained the diver is determine how deep they can dive.
The equipment used in this process is called a scuba. It is a self-contained underwater breathing apparatus that allows the diver to breathe while under water. It is transported by the diver. For this to work, the pressure of inhaled breath needs to balance the environmental or ambient pressure to permit inflation of lungs. The divers also need scuba half mask. It covers the eyes and nose and also mouthpieces to supply the gas needed for breathing from the rebreather or demand valve. The mask also come in full. It covers the nose, mouth, and eyes and often permits divers to breathe via their noses.
Another major requirement is diving gas. It is a gas containing a mixture of trace gases, nitrogen, and oxygen. It is vital for divers to control their rates of descending and ascending in water. By doing this, there will be maintenance of a constant depth in 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.
