Poseidon

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. Poseidon also invented and patented the dry zip entry drysuit known as The Unisuit which is without doubt the forefather of every drysuit made today. Their regulators use unorthodox mechanisms and are unique amongst the huge choice in today’s markets. However, they are excellent and proven in all diving environments including the US Navy’s cold water tests.
