USS Oriskany
The Poseidon Discovery Mk VI & SE7EN is the world's first rebreather for recreational divers. It's a fully closed, fully automated unit that will make you see diving in a different light.
The system comprises a breathing loop (mouthpiece, hoses, counter lungs and backpack) with associated electronics module, and two independent gas cylinders. One contains 100% compressed oxygen which is added to the breathing loop as the diver consumes it. The second cylinder typically contains compressed air, diluent, to compensate for compression in the breathing loop as the diver goes deeper. It also has a built in back-up system, containing enough breathing gas for the diver to breathe directly in an emergency.
Poseidon's MK VI has 5 big advantages over traditional open circuit equipment: 3 hours typical dive time, Safer and easier to use, Lighter and smaller, No decompressions stops, and Silent operation makes you part of the environment; not an intruder. It is arguably the greatest breakthrough within the diving community for many decades. It may be the longest and quietest dive you will ever experience. It represents a giant leap in shifting the diving experience towards the sea of tranquility - allowing you to be an integrated part of the element our ancestors left 440 million years ago.
