Warranty Information

MK25 First Stage
The MK25 first stage offers a machined, marine-grade chrome plated body and balanced composite/stainless steel piston that would make any diver proud. It demonstrates ScubaPro's dedication to quality and creating positive diving experiences. This first stage adapts to external pressure changes and comes standard with the Thermal Insulating System (TIS), which keeps your first stage from freezing up and malfunctioning in cold water conditions. The MK25 has two high-pressure ports and five low-pressure ports.
S555 Second Stage
The S555's air-balanced flow valve allows you to breath easily and steadily throughout your dive, regardless of the air pressure within your tank. Without this feature, your breathing may change as your tank empties, leaving you working harder to fill your lungs as your dive progresses. The S555 is resistant to corrosion, which gives it a long lifespan and makes it an excellent value. The manufacturing and materials used to create this second stage make it a great choice for cold-water divers.
ScubaPro developed VIVA (Venturi-Initiated Vacuum Assist) to assist with easing each breath the diver takes. As the air is pulled into the second stage casing, a vacuum is created behind the diaphragm. In turn, the diaphragm depresses the lever that maintains the poppet open for a "power assist" breath. In addition to the VIVA, the air-balanced power inflator valve means you'll have a steady stream of air, regardless of the pressure in your tank
