Our top performing balanced piston first stage paired with our high performance air balanced second stage; this combination is SCUBAPRO's most popular regulator combination. The S600 truly matches the  MK25's characteristics and thanks to its adjustment possibilities, it adapts to all diving conditions and all diver preferences. Ease of breathing is the essence of this system.
