Scuba diving was invented during World War II by the United States underwater demolition team and is credited to Dr. Christian Lambertsen for his invention and use for underwater warfare. After World War II the term “Scuba” began to come into wider usage as a way of referring to the carrying of underwater pressure tanks and use of a regulator, air tanks, mask and swim fins.
The most common type of Scuba Diving gear uses a mask and what is called the “Open Circuit” method of scuba diving. It is using a 2 stage breathing regulator, and it has a single pressure tank. The first regulator is actually on the air tank, and the second is at the breathing hose mouthpiece.
The air tank has about 3000 pounds per square inch of air, and the first regulator reduces the pressure to about 145 psi. Then, the second regulator reduces the pressure even further, to a low pressure that is provided when the person breathes in.
Most diving air tanks use normal air which is about 21 percent oxygen and 78 percent nitrogen, but there are other types of air tanks that are used, but these take special training to be able to use them. Diving masks and full face masks are used to help a diver to be able to see under water.
Scuba divers normally have to become certified, in the process of becoming certified the person is given a variety of different training, that teaches them about how to be a scuba diver, and different issues that they must deal with. Scuba diving is a fun and exciting hobby, but it is one that takes training to be able to deal with all of the different issues.
One of the people that have been responsible for helping raise the level of awareness in modern scuba diving has been adventurer and explorer Jacques Yves Cousteau. He was the person that developed the “Aqua Lung” design in scuba gear. He was involved in a television series in the 1970s in the United States that helped make Scuba diving more readily accepted and known around the world.
Jacques Cousteau has always been a defender of the environment up until the time of his death, and he was known and loved around the world for his advance of scuba diving. He showed the world a lot about the underworld oceans and aquatic life, and is responsible for raising the visibility of undersea life for the world.
The history of Scuba diving is varied and has been growing, The sport used to be reserved only for those in the military and for people with a great deal of money, but in recent years scuba diving has become more accessible to more people. Scuba diving can be done for a small amount of money now with some of the advance scuba gear.
