Many people of the world had practiced of breath holding diving from many years. Scuba diving has free diving, like free diving and skin diving. In 1771, Sieur Freminet, who was a Frenchman, invented the device of scuba diving. It was a self contained air device by the Freminet. A major hurdle of diving was to stay under the water for a long time. People used to begin the diving bells with air from the surface of the water in 16th century. England and France made suits for the diving in 16th century for the depth of 60 feet. In America, more than 2.6 million scuba diving Americans struggle in their wet suits. The Americans spent $500 on the equipment and travel in only one year. Catalina divers very first time dive in Catalina Island in 1957. There is always a strong relationship of human beings with rivers and sea. He travels upon them to approach at his destinations and dive in them to get his food. Today, there is some special equipment which is used for diving called scuba diving. Scuba diving is the use of independent breathing equipment to stay under the water for long periods of time. This equipment is used both for recreational and professional diving.

The beginning of scuba diving has redefined undersea diving altogether. With the advancement of technology, scuba diving permitted people to dive deep below the float up of the water and still be capable to breathe. Opening new possibilities for examination, scuba diving presents unlimited opportunities to untie the mysteries of the underwater world. The scuba diving system is the result of general technological research and modernism spanning since almost 300 years. Scuba diving is now the most extensively used system for breathing underwater. Scuba diving also proposes the divers unlimited liberty of underwater movement, because they go for a dip with fins, minus any heavy equipment. The scuba diving is moderately inexpensive and simple to work and maintain. Scuba diving is now used for spare time diving, as well as for performing underwater tasks for military, scientific and commercial purposes. Separately from the conservative mask and fins, a basic scuba set includes a cylinder of compacted air attached to two stages. The reason of the regulator scuba set is to lower the air weight from the cylinder and assign it to the diver as required.

Scuba diving is usually classified into two types. The first type of scuba diving is open scuba diving and the other one is closed scuba diving. Open scuba diving permits the diver to breathe air from a cylinder or canister, and the blew-out air goes into the water and goes up to the surface as soap suds. Nowadays, scuba diving has also become an international game.
