MK25 EVO / S620Ti Dive Regulator System

Product Description

The SCUBAPRO MK25 EVO / S620Ti regulator system combines one of SCUBAPRO’s most trusted first stages with a lightweight, high-performance second stage to create a versatile regulator suitable for all diving conditions and water temperatures.

The MK25 EVO first stage features an air-balanced flow-through piston design in a chrome-plated brass body, delivering instant air delivery, exceptional breathing sensitivity, and consistent airflow regardless of depth, tank pressure, or breathing rate. The patented XTIS (Extended Thermal Insulating System) improves cold-water performance by insulating the internal mechanism and delaying ice formation, while anti-freeze protection ensures reliable operation in extreme conditions.

The S620Ti second stage incorporates the proven performance of the S600 in a smaller, lighter design while maintaining the same diaphragm size for maximum breathing sensitivity. A full titanium barrel and titanium inlet tube provide durability, corrosion resistance, and reduced weight. The reinforced technopolymer casing with stainless steel frame ensures long-term reliability even under heavy use.

A large purge button, reengineered exhaust tee, and compact Hi-Flow mouthpiece improve airflow, comfort, and bubble management. With diver-adjustable breathing controls and premium construction, this regulator system delivers dependable performance in warm, temperate, and cold water environments.
