A mode of underwater diving is in which a diver uses a scuba is known as scuba diving. The diver uses a self-contained underwater breathing apparatus, referred to as he scuba. Unlike other modes of diving that require divers to rely on air supply from the surface or breath hold, this one involves using scubas. Divers usually carry their own source of air supply. To meet professionals in scuba diving Seagrove deserves to be prioritized.

The two main types came into existence in the mid-20Th century. They are called closed circuit and the open circuit. In the open circuit, the air exhaled by the diver is vented directly into water, while in the closed circuit, the respired air is recycled. Recycling involves adding oxygen to the respired air and then moving it back to be inhaled by 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.

Underwater surrounding is a major concern in many fields of study. These studies include underwater photography and videography. Underwater world can be researched by professional divers. This includes marine biology, hydrology, underwater archaeology and scientific diving. It is a profession that is done full time. Lessons on scuba divers can be provided by professional divers.

There are some legal and logistic constraints governing equipment to be used for the diving. Where divers require mobility and large range of movement scubas can be used. Higher risk work particularly in commercial settings, then surface-supplied equipment is allowed. Depth range the diver can achieve depends on the training levels and the rules differ according to various countries.

Scubas are the equipment that is used during diving. It is a self-contained underwater tool that enables the diver to breath while underwater. The diver transports it on their backs. The pressure of the inhaled breath should be equal to that of the surrounding thus allowing inflation of the lungs. They also require having a mask. The mask helps in covering the nose and eyes. Also the mouthpiece is covered so that it can supply the gas needed for breathing from demand valve. The masks usually come in full. It is very rare allowing the diver to breathe through the nose.

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.

One may encounter certain risks while in the water. The problems are normally caused by poor gas management, equipment misuse, rough water, pre-existing health problems and poor buoyancy control. Some of the risks may be foreseen while others may not be seen. One should undergo thorough lessons taught by a professional diver, this helps one to be the best scuba diver.
