SCUBAPRO's top regulator technology is on display with the high-tech, ultralight MK25T EVO/S620 X-Ti Diving Regulator System. The MK25T EVO is machined from a solid block of ultra-durable, lightweight titanium that won't corrode, even in concentrated saltwater conditions. An air-balanced flow-through piston provides effortless airflow unaffected by depth, tank pressure, or breathing rate. SCUBAPRO'S patented Extended Thermal Insulating System insulates the inner mechanism, improving cold-water resistance and delaying ice formation without compromising breathing performance. Dive confidently at varying depths with the intuitive user controls, which include an easy-grip, diver-adjustable inhalation effort knob, a large purge button, and a coaxial VIVA switch to control free flow. Driven to constantly innovate and improve the diving experience, SCUBAPRO builds high-quality equipment for the work, sport, and lifestyle of people whose passion is found below the surface. Features INT connector, two high-pressure ports, and five high-flow low-pressure ports; one-year warranty.
