In 1958 Ingvar Elfström founded Poseidon. With a quest to solve a range of diving related problems his innovative solutions securely placed him among the great entrepreneurial prioneers. Elfström's legacy has continued and Poseidon equipment enjoys a stellar reputation within the diving community.
We’ve always prided ourselves on being different – looking at things from new angles and finding new ways to solve old problems, improving but never copying. For more than 60 years that ambition has taken us from the first single hose regulator, the servo-assisted Jetstream and Xstream to the extraordinary Poseidon SE7EN+ rebreather.
innovation, performace, quality and safety
We believe the equipment you take underwater is a life-preserving device. As divers ourselves, we never compromise with quality, and we never stop searching for new ways to improve safety and enhance the diving experience.
Whether we develop products, creating software, or supporting training programs, at the end of the day, Poseidon stands for four things above everything else.
royal approved diving equipment
Sweden has been a monarchy for over a thousand years. For all this time, craftsmen, merchants and others have been delivering goods and services to the monarch and the Royal Family.

Poseidon x divers against ghost nets
The fact that our waters and animals depending on it are under extreme pressure and threat has probably not passed anyone. At Poseidon we do our best to minimize our impact and has sustainabilty top-in-mind whether it concerns developing new products, agreements with subcontractors and freight companies, travelling or at what level the dishwasher is concidered full.
Divers Against Ghost Nets are on a mission to clean the waters and share the knowledge on how to safely locate and recover ghost nets around the world. We are proud partners for the work for a better marine life.
