The EVO version of Scubapro's legendary MK25 first stage has been upgraded to increase its freezing resistance by 30%, making Scubapro's flagship 1st stage a serious cold water regulator!

The air balanced flow-through piston design is unaffected by your breathing rate, depth or tank pressure! A coated spring, anti-freeze cap, bigger chrome-plated brass body all work together with the Extended Thermal Insulating System (XTIS), which fully isolates the mechanical elements from the cold to improve the MK25's (cold-water) performance!

This stage can be positioned upwards or downwards and the 5 high flow low pressure ports (4 on a swivel, 1 at the bottom) increase your hose routing options.

Weight: 790gr (yoke), 570gr (DIN)

Airflow at 200 bar is an incredible 8500L.
