That is if you are into scuba diving.
Scuba Diving History
Scuba diving has come a long way since its invention. In 1771, British engineer, John Smeaton invented the air pump. A hose was connected between the air pump and the diving barrel, allowing air to be pumped to the diver. In 1772, Frenchmen, Sieur Freminet invented a rebreathing device that recycled the exhaled air from inside of the barrel, this was the first self-contained air device. Freminet’s invention was a poor one, the inventor died from lack of oxygen after being in his own device for twenty minutes.

In 1825, English inventor, William James designed another self-contained breather, a cylindrical iron “belt” attached to a copper helmet. The belt held about 450 psi of air, enough for a seven-minute dive.
In 1876, Englishmen, Henry Fleuss invented a closed circuit, oxygen rebreather. His invention was originally intended to be used in the repair of an iron door of a flooded ship’s chamber. Fleuss then decided to use his invention for a thirty-foot deep dive underwater. He died from the pure oxygen; oxygen is toxic to humans under pressure.
In 1873, Benoît Rouquayrol and Auguste Denayrouze built a new piece of equipment a rigid diving suit with a safer air supply, however it weighed about 200 pounds.
The modern demand regulator was invented by Emile Gagnan and Jacques Cousteau along with an improved autonomous diving suit. In 1942, redesigned a car regulator and invented a demand regulator that would automatically fresh air when a diver breathed. A year later in 1943, Cousteau and Gagnan began selling the Aqua-Lung.
Almost anyone can learn to scuba dive. There is a basic level of health and fitness that you need to have to be safe and to enjoy your time underwater. You will be required to fill out a medical form before starting a certification class. In some cases, you may have to see a doctor before you begin training.
There are many scuba classes for kids under 14 years of age. Being a senior citizen is not a problem either, provided you have a fair level of fitness and approval from a doctor. There are also training programs for the disabled so they too can enjoy the sport of scuba diving.
What Does the Word S.C.U.B.A. Stand For: The word S.C.U.B.A. is an acronym for
Exploring Starboard, USS Kittiwake, Grand Cayman
Self-Contained-Underwater-Breathing-Apparatus. A scuba system allows autonomous diving (diving without an air line to the surface). The word also describes the sport of scuba diving.
The term scuba originated during WWII. It was used to describe navy divers who used oxygen rebreathers to attack enemy ships from underwater. Today you can use the word scuba to refer to the sport of scuba diving or to the equipment used by those who take part in the sport.
Scuba diving today has an estimated 3 to 6 million divers global and is growing rapidly. With today’s advanced equipment, availability of online learning, getting started with Scuba Diving has never been easier. So come join the millions of other divers and take fish pictures, explore shipwrecks, glide over coral reefs and enjoy the beauty and fragility of our wonderful oceans.
