Scuba diving techniques with gas mixtures (Nitrox, Heliox, Trimix) or using rebreathers (also called assistive devices rebreathing or rebreathers) are considered within the category of technical or professional diving. This is because of risk and the level of preparation required by the divers who uses them (snorkeling grace bay beach).
The term defines exactitude scuba diving in the sea, which is also and by far the most practiced diving worldwide. When practiced in caves or flooded mine shafts it is called cave diving and diving in mountain lakes - high dive. In almost all modes that use breathing apparatus the most widely used is the scuba (a regulator fed by one or more bottles of compressed air).
The regulator reduces high pressure of the water surrounding the diver, so that he can breathe normally and independently of cables and air supply tubes from the surface. In 1943 Jacques-Yves Cousteau and Emile Gagnan were the inventors of regulators, which are still currently used in (professional and recreational) scuba diving.
However, current safety standards require a number of tools that let you know how deep you are and what air pressure is left, called depth gauge and pressure gauge, respectively. Dive computers are also becoming popular, depending on depth, mixture of air and the time spent underwater, they indicate at all times the depth range where you can stay.
The snorkel is a fairly flexible plastic tube rod-shaped that allows you to breathe with your face underwater. Divers use in apnea, and is part of mandatory equipment for recreational divers who used to breathe when you are on the surface, thus saving the air from his bottle. There are a variety of snorkels to facilitate expelling water through tube trap waves, which prevent water from entering the open, rigid, flexible end.
But it was not until 1942 that the technology would make a giant leap and definitely allow man to dive independently from the surface. In that year Emile Gagnan (engineer employed at Air Liquide, Paris company specializing in compressed gases) miniaturized one regulator to suit gasifier car engines, as the Germans occupied France and confiscated all gasoline. Henri Melchior, father of Jacques-Yves Cousteau and owner of Air Liquide, thought then that this regulator might be useful to his son Cousteau. Melchior knew that the latter was trying to develop a underwater breathing system to grant full autonomy to the diver.
There are different certifying agencies and government or private entities that are responsible for ensuring these processes. The main ones are: World Underwater Federation (CMAS) that is responsible for issuing their degrees. SSI Scuba Schools International (SSI). These agencies are guarantors of knowledge of minimum training standards for each level of competence of their members. The level of competence certified to a diver is reflected in type of degree.
From this invention many improvements and innovations have been made in both design and quality, but the basic principle remains. Surprisingly, this technology has remained virtually unchanged for over 50 years. Recreational diving is practiced in two forms: free diving or apnea (descent into the deep sea, ie, without traditional diving equipment). Techniques around apnea and scuba air belong to the recreational category.
