"HP / LP ports" is the number of high-pressure and low-pressure ports on the first stage, which caps how many accessories (transmitter, SPG, inflator, second second-stage) you can run at once.

Pros
  • Won ScubaLab's 2025 Best Buy award for independently tested value
  • One of the more compact first stages in its class, a common pick for dive travel
  • C370 second stage has interchangeable color frames for personalization
Cons
  • No octopus included, budget for a second second stage
  • Also sold in an INT/yoke version, confirm the listing matches this DIN 300 spec
  • Scubapro lists this DIN/C370 configuration as discontinued on its own site even though retailers still stock it, worth confirming current availability before buying
Diver community sentiment
Mostly positive

Divers on Scubaboard and reviewers consistently describe the MK11 EVO/C370 as a reliable, well-built, compact "value" regulator from a premium brand, with smooth, easy, quiet breathing and good parts/service availability. The main recurring caveat is that it's viewed as a warm-to-moderate-water regulator rather than a true cold-water specialist, lacking the sealed/anti-freeze chamber of Scubapro's higher-end MK17/MK25 lines, though several posters report trouble-free use down into the high-30s to mid-40s°F. Minor gripes include a cosmetic faceplate insert on the C370 that can bend/snag and a tendency to freeflow if breathing resistance is set too low.

The MK11 EVO/C370 is Scubapro’s mid-tier workhorse, popular with dive travelers for its compact first stage and colour-customizable second stage. It won ScubaLab’s 2025 Best Buy award, making the case for divers who want sealed, cold-water-rated performance and an adjustable second stage without paying flagship MK17 EVO 2/S620 Ti pricing.
