The Mk25/S600 is one of the most popular Scubapro regulators or all time. It is a high performance reg that is regarded by those that use it as the best reg in the world!

The regulator is a result of years of technical know how and innovation starting back at the Scubapro MK5 first stage.  The Mk25/S600 has evolved to become a time proven bullet-proof design with reliability and performance second to none.

The characteristics that are loved by so many vary depending on the diver, many love the light breathing characteristics, even at vast depths whilst others love the compactness of the 2nd stage and the lack of weight in the mouth.

The second stage is an air balanced design with precision moulded, lightweight components and anti freeze materials that provide high corrosion resistance and enhanced cold water resistance.
