 MK25 EVO/S620Ti


The MK25 first stage offers state-of-the-art technology and quality. It offers an amazing 10,000 litres per minute (instantaneous flow), which means this first stage is up to any task you ask of it in almost any diving situation. It is incredibly reliable in cold water and is as versatile as the divers who use it.

This first stage boasts of a machined, marine-grade chrome-plated brass body, which means it is tough. The MK25 is highly resistant to corrosion and promises to be your work horse for MANY, many dives. Ideally suited to cold water diving, improves heat transfer and increases resistance to freezing.

 The name “AIR“ stands for Alternate Inflator Regulator. This concept was invented by SCUBAPRO in 1979 and integrates in the same housing, a regulator second stage and a balanced inflator. Often imitated but never equaled, the Air 2 can be installed on most any BCD and eliminates the need for a back up regulator.

When needed, the Air 2 allows the diver to breathe normally as from any second stage. While breathing, the diver can simultaneously and rapidly inflate or deflate the BC. Fastest reaction time in out of air situations.



Classic downstream second stage valve. Recognized for many years for its reliable performance due to the robust design and low maintenance. Air-balanced power inflator valve. For smooth and reliable operation regardless of tank pressure.



Fixed VIVA flow vane. Fixed in the pre-tuned ideal position for safe and uncomplicated use.



Single hose configuration. Eliminates the need for a separate alternate air source.

One hand operation. Instinctive operation of its ergonomic case. Self-flushing mechanism. A single push on the purge valve removes all dirt.
