It’s the perfect go-anywhere reg for divers who like to keep their diving simple and affordable. The most economical first stage in SCUBAPRO’s line, the MK2 EVO is the only downstream piston-style first stage with internal components specifically designed to resist freezing in extreme cold-water conditions. When teamed with the R195, this reg system is reliable, easy to maintain, easy to use, and with its left or right hose routing capability, it’s also the perfect system for use on stage or pony bottles.
