The ScubaPro MK11 EVO/C370 pairs a compact balanced diaphragm first stage with the air-balanced C370 second stage, built for divers who want a lightweight, travel-friendly regulator without the bulk of a heavier cold-water system. The MK11 EVO first stage is a forged brass body with metal fins to improve thermal exchange, keeping performance consistent in colder water, and delivers air promptly across a range of tank pressures. Four low-pressure ports and two high-pressure ports, angled at 15 degrees, allow flexible hose routing for a pressure gauge, transmitter, or additional accessories.

The C370 second stage uses the same air-balanced valve design found across ScubaPro's current regulator range, smoothing inhalation effort at varying depths and supply pressures. A diver-adjustable inhalation effort knob and a dive/pre-dive lever give further control over breathing resistance and freeflow at the surface. The second stage's impact-resistant faceplate is colour-customisable, with six colour frames available separately for divers who want to personalise the setup beyond the standard finish.

This configuration is available in two standard finishes. The graphite version ships with a graphite-coloured C370 frame as standard, while the white version pairs a white first-stage bumper, saddle, cap, and DIN or INT wheel with a matching white second-stage casing, front cover, and exhaust tee, both finished with dark grey logos and accents. Both variants share identical internal mechanisms and performance; the distinction is cosmetic. The system is available in both DIN and yoke (INT) configurations and is backed by ScubaPro's limited lifetime warranty. Nitrox use above 21% requires compliance with relevant national regulations and standard nitrox-specific servicing procedures.
