Underwater diving was practiced in ancient cultures to gather food and other valuable resources such as pearls and precious coral, and later to reclaim sunken valuables, and to help aid military campaigns. Breathhold diving was the only method available, occasionally using reed snorkels in shallow water, and stone weights for deeper dives. [1]
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.
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 history of breath-hold diving goes back at least to classical times, and there is evidence of prehistoric hunting and gathering of seafoods that may have involved underwater swimming. Technical advances allowing the provision of breathing gas to a diver underwater at ambient pressure are recent, and self-contained breathing systems ...
The invention revolutionised autonomous underwater diving by providing a compact, reliable system capable of a greater depth range and endurance than its precursors, and was a major factor influencing the development of recreational scuba diving after WWII. The twin-hose Aqua-Lung demand regulator is the foundation of all modern scuba regulators.
Recreational scuba diver The undersea kelp forest of Anacapa Island off of the coast of Oxnard, California Diver looking at a shipwreck in the Caribbean Sea. 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.

Monofin made in 1969 by Franco Pavone in Bologna. 1949: Kurt Schaefer, [3] who invented an underwater film camera during wartime military service in Italy, designs a pair of homemade swimming fins, which he proceeds to fasten together with straps and cords to create what is probably the world's first monofin.
The highest level of collegiate competition is the NCAA Division 1 Swimming and Diving Championship. Events at the championship include 1 metre springboard, 3 metre springboard, and platform, as well as various swimming individual and relay events. The points scored by swimmers and divers are combined to determine a team swimming & diving champion.
