In this package you get two solid and reliable parts, which can be built for use in colder waters, with metal parts for better cold dissipation and thereby prevent freezing of mechanisms inside both the first and second stages. With the extremely hard-wearing Black Tech alloy, you are protected against everything that may occur, both above and below sea level.
MK25 EVO BLACK TECH First Stage:
Balanced flow through piston provides a constant and effortless airflow unaffected by depth, tank pressure or breathing.
Patent pending XTIS (Extended thermal insulating system) isolates the inner core from the water and provides an improvement of cold water resistance by 30% and delays ice formation in cold water.
New spring insulating coating provides fantastic properties against the cold. In addition, there is a frost-proof cap, larger body and hood thread which, together with XTIS, provide the best diving performance in cold water.
Two opposing high pressure ports allow the first stage to be positioned either up or down.
Five high flow low pressure ports on a swivel tower maximize hose routing options.
External intermediate adjustment pressure allows technicians to fine-tune performance quickly and easily.
Available in a 3364psi / 232bar INT configuration.
