The dive... the ultimate escape and the ultimate sensation of being. Below the surface - do not disturb and don't be disturbed. All the gadgets and equipment that seemed so cool above will do their job and disappear into your peace of mind. They have done their job on North Sea oil rigs, they have done their job in complex Arctic Search and Rescue missions. They will do the job for you and be quiet about their business - allowing you to be filled with presence. This achievement has been a long journey. 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 pioneers. Elfström's legacy has been continued and Poseidon equipment enjoys a stellar reputation within the diving community. Arguably though, no breakthrough matching the significance of Elfström's early work has been accomplished - that is until the launch of the Poseidon MKVI. Poseidon's Fully Automatic Rebreather - the Poseidon SE7EN+, which is the 3rd generation rebreather system based on the original MKVI - is arguably the greatest breakthrough within the diving community for many decades. It may be the longest and quietest dive you will ever experience - we will not be quiet about its existence. It represents a giant leap in shifting the diving experience towards the sea of tranquillity - allowing us to be an integrated part of the element our ancestors left 440 million years ago.
