Poseidon MKVI Recreational Rebreathers

World’s first recreational rebreather

The Poseidon MKVI is the world’s first rebreather for recreational divers. It’s a fully­closed, fully ­automated unit that will make you see diving in a different light.

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’s also a back­up system, containing enough breathable gas to bring the diver to the surface in case of an emergency.

Poseidon’s MKVI 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

  • Silent operation makes you part of the environment; not just a visitor
