A scuba set is characterized by full independence from the surface during use, by providing breathing gas carried by the diver. Early attempts to reach this autonomy were made in the 18th century by the Englishman John Lethbridge, who invented and successfully built his own underwater diving machine in 1715, but though the air supply was carried in the diving apparatus, it relied on surface ...
The timeline of underwater diving technology is a chronological list of notable events in the history of the development of underwater diving equipment.With the partial exception of breath-hold diving, the development of underwater diving capacity, scope, and popularity, has been closely linked to available technology, and the physiological constraints of the underwater environment.
History of underwater diving. 16th century Islamic painting of Alexander the Great lowered in a glass diving bell. 1849 illustration of various diving equipment. The history of underwater diving starts with freediving as a widespread means of hunting and gathering, both for food and other valuable resources such as pearls and coral.
The history of scuba diving is closely linked with the history of scuba equipment.By the turn of the twentieth century, two basic architectures for underwater breathing apparatus had been pioneered; open-circuit surface supplied equipment where the diver's exhaled gas is vented directly into the water, and closed-circuit breathing apparatus where the diver's carbon dioxide is filtered from ...

The Clearance Divers Breathing Apparatus (CDBA) is a type of rebreather made by Siebe Gorman in England . The British Royal Navy used it for many years. [ 1] It was for underwater work rather than for combat diving. The main oxygen cylinders are on the diver's back.
