SCUBAPRO MK25 EVO 1st Stage Regulator

The SCUBAPRO MK25 EVO First Stage Regulator has been designed with outstanding quality and unbeatable engineering. This regulator is the top-performing air-balanced piston first stage for flawless performance and ease of breathing. With this air-balanced flow-through piston-style first stage mounted to an air cylinder, scuba divers are guaranteed a reliable, low-effort delivery of air, no matter how hard they’re breathing, how deep they’re diving, or what their pressure gauges read. This is the preferred regulator of professionals, or any diver embarking on long, deep dives that require ultra-high performing cold-water protection.

With the introduction of the new Extended Thermal Insulating System (XTIS), the MK25 EVO proves to be a superb performer in extreme cold-water conditions as well. With the patent-pending XTIS, the MK25 EVO offers thermal insulation from the environment by fully isolating the mechanical elements of the first stage from the cold, increasing its freezing resistance 30 percent over the current MK25 without compromising breathing performance. This enables divers to enjoy an ultra-fast breathing response, instant delivery of air on demand, great sensitivity and extra-high airflow regardless of water temperature.

In addition to the XTIS, the MK25 EVO is built with highly technical internal components that are all designed to enhance cold-water breathing performance. These include a new spring insulating coating, a new body insulating bushing, a new antifreeze cap, and a bigger body and cap thread. Externally, supplementary fins have been added to the machined body to provide extra thermal exchange.

Like the standard MK25, the MK25 EVO also offers an external intermediate pressure adjustment for hassle-free maintenance, and two high pressure ports and five low pressure ports mounted on a swivel turret for convenient hose routing. The reg is available in a choice of INT or DIN configurations, and meets the new EN250-2014 standards for cold-water diving.

Note: Available in 232 bar / 3364 psi INT and 300 bar / 4350 psi DIN configurations.
