Scuba Diving Gear
The Rouquayrol-Denayrouze apparatus didn't achieve as much success because the compressed-air tanks made with the technology of the time could only hold 30 atmospheres , which allowed dives of only 30 minutes at no more than ten meters deep. When the Aqua-Lung became available for commercial use, divers around the world found a scuba device smaller and easier to carry than its precursor, which in fact was almost completely unknown outside France.
In addition, and most importantly, the Aqua-Lung could be mounted on stronger and reliable air tanks holding up to atmospheres, [9] allowing extension of diving duration to more than an hour at significant depths including the needed time for decompression stops. They have since been made by various manufacturers with varying design details and numbers of cylinders. Like modern open-circuit scuba with single-hose regulators, they consisted of one or more high pressure diving cylinders and a diving regulator the Aqua-Lung that supplied the diver with breathing gas at ambient pressure via a demand valve.
The original "Aqua-Lung" was an "open-circuit" design so-called because gas flows from the cylinder, to the diver, out into the water. Other scuba systems that were invented before the "Aqua-Lung" were "closed circuit" or " rebreather ". In these apparatuses, breathing gas flows from the cylinder to the diver, through a scrubber which removes carbon dioxide , back to a secondary bag or counter-lung, and then back to the diver again, in a closed loop.
The Aqua-Lung was not the first breathing apparatus, but it was the most popular.

The twin-hose or double hose Aqua-Lung "demand regulator" forms the foundation of all modern scuba regulators. A diaphragm is used to deliver the breathing gas to the diver on demand, at ambient water pressure. The first modern two stage, single hose regulator was manufactured and distributed as the "Sport Diver" by Divers Supply in Wilmington California beginning in This design, an offshoot of surface supplied commercial gear, uses a first stage regulator mounted at the tank valve delivering air to a mouthpiece-mounted second stage via a small-diameter intermediate-pressure about psi hose.
At about the same time as Divers Supply began selling the Sport Diver regulator, Australian Ted Eldred designed a similar single hose system which he marketed as the Porpoise.
Today, virtually all modern open-circuit SCUBA gear uses this design, though Aqualung did market a "modern" double hose Mistral model in and There is controversy over the invention of the first single hose regulator. The invention was motivated by an effort to bypass Aqua-Lung's patent on the double hose regulator.
This patent involved the return of exhaust gas to the regulator to reduce the differential pressure and therefore reduce work of breathing.

The single hose regulator accomplishes this by relocating a portion of the regulator to the point of exhaust, rather than routing the exhaust back to the regulator. Divers Supply, which had been supplying commercial surface-supplied breathing systems, replaced the surface air supply with a tank-mounted first stage pressure regulator. Ted Eldred claims to have developed his nearly identical system contemporaneously in Australia. Since neither party chose to patent the invention, it is difficult now to know if either design was inspired by the other or if, in fact, they were truly spontaneous inventions.
There seems to be some evidence that the Divers Supply unit hit the market just prior to the Eldred Porpoise, but there is no evidence that Eldred was aware of it. In the early years of scuba diving in Britain, "tadpole" was a nickname for a type of diving gear that had two meanings:. Aqualung , Aqua-Lung , and Aqua Lung are registered trademarks for scuba diving breathing equipment. That trade name was originally owned in the United States by a company known as U. Divers now Aqua Lung America.
