This was the world's first commercially available single-hose scuba unit and was the forerunner of most sport SCUBA equipment produced today. Only about 12,000 were made. [108] After World War II Lambertsen called his 1940-1944 rebreather LARU (for Lambertsen Amphibious Respiratory Unit) but as of 1952 Lambertsen renamed his invention and ...
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 ...
Scuba systems invented before the Aqua-Lung were mostly closed circuit rebreather equipment, in which breathing gas flows through an ambient pressure hose to the diver, and exhaled gas is returned through a scrubber which removes carbon dioxide, to a counter-lung reservoir. Some fresh gas is added to maintain the oxygen content and is then ...

During the 1940s, Cousteau is credited with improving the Aqua-Lung design which gave birth to the open-circuit scuba technology used today. According to his first book, The Silent World: A Story of Undersea Discovery and Adventure (1953), Cousteau started diving with Fernez goggles in 1936, and in 1939 used the self-contained underwater ...
Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface breathing gas supply, and therefore has a limited but variable endurance. [1] The word scuba is an acronym for "Self-Contained Underwater Breathing Apparatus" and was coined by Christian J. Lambertsen in a patent ...
The word SCUBA was coined in 1952 by Major Christian Lambertsen who served in the U.S. Army Medical Corps from 1944 to 1946 as a physician. [1] Lambertsen first called the closed-circuit rebreather apparatus he had invented "Laru", an (acronym for Lambertsen Amphibious Respiratory Unit) but, in 1952, rejected the term "Laru" for "SCUBA" ("Self-Contained Underwater Breathing Apparatus").

Ted Eldred was recognised in later life, by the Historical Divers Society (South-East Asia Pacific), as the inventor of the first successful commercially produced single hose SCUBA. [2] Eldred made his last dive with his grandson Adam, at an event in Ted Eldred's honor. The single hose SCUBA is the type in use around the world today.
