Aqualung

Aqua Lung America, formerly known as U.S. Divers Company, is a leading American manufacturer of scuba equipment, based in Carlsbad, California. Originally established in 1943 by Jacques-Yves Cousteau and Émile Gagnan, Aqua Lung International (formerly La Spirotechnique) was later founded as a division of Air Liquide to sell the innovative "Aqua-Lung" regulators. Renamed U.S. Divers Company in 1952, it played a significant role in introducing scuba diving to the United States. After a series of ownership changes, including a sale to Montagu Private Equity in 2016, the company rebranded as Aqua Lung America. Despite the name change, the U.S. Divers brand continues as a trademark for Aqua Lung's snorkeling equipment line.
