Poseidon has over a half-century of experience in designing and delivering the newest, most high-quality scuba diving gear in the field. From top-of-the-line rebreathers and regulators to buoyancy compensators, gauges, and masks, when it comes to the water, you can't beat Poseidon. See more  


The Poseidon company was founded in 1958 in Gothenburg, Sweden, by Dennis Österlund and Ingvar Elvström. It was the first in the world to produce a single hose regulator, the breathing apparatus used by nearly every recreational diver ever since. The original name – Aqua Sports – was changed as the company began to look at new markets for its products.

Today, Poseidon exports to almost every country in the world, bringing the ultimate in diving gear to demanding recreational divers, rescue divers and the military. Manufacturing and research have taken place at the company’s modern factory and test facility on the outskirts of Gothenburg since the mid-80s.

The last few years have marked the latest chapter of the Poseidon story, with new owners, new investment, and the decision to develop a new generation of diving apparatus.

Poseidon has a record of innovation stretching over more than 50 years. Today’s product range includes world-beating regulators, drysuits, rebreathers, buoyancy compensators, and a host of add-ons and accessories. But whether it’s developing products, creating software, or supporting training programs, at the end of the day, Poseidon stands for just three things. Quality, safety, and performance. See less
