Scubapro MK 25 / S600 Regulator

The high performance MK25 EVO/S600 reg system is well-known for its low work of breathing and tremendous reserve capacity. The Scubapro MK 25 first stage lets you enjoy an ultra-fast breathing response, instant delivery of air on demand, great sensitivity and extra-high airflow — regardless of how cold the water is. This is made possible with SCUBAPRO s exclusive patent-pending Extended Thermal Insulating System (XTIS) that fully isolates the mechanical elements of the first stage from the cold, increasing its freezing resistance 30 percent over previous versions of the MK25 without compromising breathing performance. The Scubapro S600, with its rugged fiberglass casing and stainless steel front face and ring, delivers smooth and easy inhalation and exhalation while offering efficient user controls, including a powerful purge, an inhalation effort control knob and Venturi Initiated Vacuum Assist (VIVA) dive/pre-dive switch.
