The Scubapro MK25 EVO + S620Ti Regulator White combines SCUBAPRO's proven high-performance MK25 EVO balanced piston first stage with the lightweight, air-balanced S620 Ti second stage. Designed to deliver smooth, effortless breathing in demanding conditions, this premium regulator system is equally suited to cold-water UK diving, deep dives and travelling the world.
The MK25 EVO first stage uses a direct-flow air-balanced piston housed in a nickel-plated brass body, providing a fast and consistent supply of air regardless of depth, cylinder pressure or breathing rate. This gives the regulator an exceptionally responsive feel, with immediate air delivery when you need it.
For cold-water divers, the MK25 EVO features SCUBAPRO's Extended Thermal Insulating System (XTIS). This system isolates the internal mechanical components from the cold and increases freeze resistance by up to 30% compared with previous MK25 versions. Additional insulating components, including the spring liner, housing sleeve and anti-freeze head, work together to help maintain reliable performance in extremely cold water.
The MK25 EVO also provides excellent flexibility when setting up your regulator. Two opposing high-pressure ports allow the first stage to be positioned upwards or downwards, while five high-flow low-pressure ports on a rotating turret offer plenty of options for hose routing. Intermediate pressure can also be externally adjusted by a qualified service technician to optimise performance.
Moving to the second stage, the S620 Ti takes the proven performance of SCUBAPRO's S600 and packages it into a smaller and lighter design. Its air-balanced valve helps reduce inhalation effort as depth and delivery pressure change, providing smooth and effortless breathing throughout the dive.
The S620 Ti's full titanium cylindrical sleeve keeps weight down while providing excellent corrosion resistance and long-term durability. The larger S600-style diaphragm is retained within the compact housing, helping deliver high respiratory sensitivity without adding unnecessary bulk.
Diver-adjustable controls give you further control over breathing performance, including an inhalation effort adjustment knob and VIVA (Venturi-Initiated Vacuum Assist) lever. The large purge button is designed for easy operation, while the oversized high-flow hose helps maximise airflow with every breath.
The S620 Ti also features a redesigned exhaust system that improves performance while directing exhaled bubbles away from the diver's field of vision — particularly useful for photographers, instructors and anyone who prefers a clear view underwater.
With its combination of air-balanced piston performance, XTIS cold-water protection, lightweight titanium construction and adjustable breathing controls, the SCUBAPRO MK25 EVO S620 Ti is a versatile premium regulator for divers who demand reliable performance in a wide range of diving conditions.
CE marked to EN250A, the MK25 EVO S620 Ti is designed for use across a broad range of diving conditions, including cold-water diving.
