Poseidon Rebreather


The Poseidon MKVI Discovery & Se7en 

The time has come that open circuit divers are switching to Rebreather Diving without having to be a Technical diver. Divers are seeing the benefits of no bubble, warm breathing gas, perfect PPO2 and easy to use diving units such as the SEVEN and the MKVI Poseidon.

World’s first recreational rebreather – The Poseidon MKVI Rebreather Discovery 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 only currently in production PADI type “R” rebreather that may be used in the PADI Rebreather & Advanced Rebreather Courses. Naturally it is supported by TDI and all other agencies as well.This is the rebreather of choice for the travelling diver as it is small enough to be carried in hand luggage without the tanks. The CCR of choice for many of our instructors for that reason. As the worlds fastest growing unit, you can be assured of worldwide support when going overseas.The simplicity of the system means that once your set up, you go diving and the unit takes care of everything else.

Technical features of the Poseidon MKVI rebreather:

Compared to Open Circuit, rebreathers have 2 big advantages: Triple actual dive time, Far less disturbing to marine life
Poseidon’s recreational unit has 4 big additional advantages: Safer and easier to use, lighter and smaller, no decompression stops, warm breathing gas


The Poseidon MKVI rebreather 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’s also a back­up system, containing enough oxygen for the diver to breathe directly in an emergency.  Poseidon’s MKVI rebreather 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 just a visitor. The MKVI, the first true technological breakthrough in decades, is a game ­changer.
