NAUTILUS CCR

The Next Best Thing to Gills

The Nautilus is a state of the art closed circuit rebreather priced and produced, for the recreational diving market.  The focus has been threefold: performance, comfort and ease of operation; all of which lead to a highly reliable and responsive CCR.  This is the next evolution in diving.  The fully closed circuit design allows for a far more personal connection to the underwater world. Once we were visitors; now we can belong. The operation of the unit is virtually silent and without bubbles. By maintaining a constant partial pressure of oxygen, the Nautilus allows for a dramatically increased dive time, less decompression obligation and less fatigue following a given dive.  The future is here.
