Poseidon is a company founded by Ingvar Elfstrom in 1958. The company is based in Sweden. Poseidon was an early innovator of regulators with their Poseidon Senior (double hose) and Cyklon Junior (single hose). The company also innovated both wetsuit and drysuits. Additionally, they developed the SEVEN+ rebreather - dubbed the world's first recreational rebreather. Poseidon is still going strong with their regulators, rebreathers, BCDs and computers.
