MK25T EVO / S620 X-Ti Dive Regulator System

Product Description

The SCUBAPRO MK25T EVO / S620 X-Ti regulator system represents the pinnacle of SCUBAPRO regulator technology, combining ultralight construction with exceptional breathing performance in all diving environments.

The MK25T EVO first stage is precision-machined from a solid block of titanium, making it extremely lightweight, corrosion-proof, and highly durable — even in concentrated saltwater conditions. Its air-balanced flow-through piston design ensures instant air delivery and smooth breathing regardless of depth, tank pressure, or breathing rate. The patented XTIS (Extended Thermal Insulating System) enhances cold-water resistance by insulating the internal mechanism and delaying ice formation in extreme conditions.

The S620 X-Ti second stage builds on the legendary S600 design in a more compact and lightweight form while maintaining the same diaphragm size for outstanding breathing sensitivity. A full titanium barrel, titanium inlet tube, and reinforced technopolymer casing with stainless steel frame provide durability without adding weight.

The regulator includes diver-adjustable breathing controls, a large purge button, and an improved exhaust tee that enhances performance while directing bubbles away from the field of vision. Together, the MK25T EVO and S620 X-Ti deliver premium breathing comfort for recreational, professional, and technical divers.
