Scubapro MK11 EVO/C370 Review: Dependable Performance at a Fair Price

For divers who want solid Scubapro quality without the premium price tag, the MK11 EVO/C370 delivers impressive value. This regulator system offers reliable performance for recreational diving, with particular strengths in cold water conditions. It’s compact, lightweight, and designed for divers who need dependable equipment for travel and general diving.

Key Specifications

The MK11 EVO first stage uses a balanced diaphragm design with an innovative double spring layout. It has two high-pressure ports and four low-pressure ports. The C370 second stage features a balanced valve and fiberglass-reinforced nylon casing. Total system weight is 1.989 lb (902 g). Price sits at $699 USD for the complete system. The regulator comes nitrox-compatible to 40% oxygen and is CE certified to EN250A European Standards for cold water diving.

Real-World Performance

Many of my customers choose the MK11 EVO/C370 as their first regulator purchase, and the feedback has been consistently positive. One student who bought this system for her Open Water course is still using it three years later for recreational diving without any issues. The breathing performance is smooth and comfortable for typical recreational depths.

The compact design makes this regulator easy to pack for travel. The forged brass body with thermal fins and plastic bumpers holds up well to normal diving abuse. A colleague instructor who uses this system for teaching mentioned that it breathes well enough that students don’t notice any difference compared to rental equipment, which is exactly what you want from an entry-level personal regulator.

The C370 second stage is lightweight and comfortable. The diver-adjustable inhalation effort knob and coaxial dive/pre-dive lever work smoothly. The large purge button is easy to find and use, even with gloves. The compact Hi-Flow mouthpiece fits comfortably for most divers.

Cold water performance is better than expected for a mid-range regulator. The balanced diaphragm design and environmental sealing handle cold water well. The metal fins on the first stage improve thermal exchange. I’ve seen this regulator used in Great Lakes diving and European cold water without problems, though as always, proper technique matters more than equipment when temperatures drop below 10°C.

Comparison Context

The MK11 EVO/C370 competes directly with the Apeks XTX50 ($649). The Apeks offers a rotating turret for better hose routing, which matters more for technical divers than recreational divers. For typical recreational diving, the performance difference is minimal. The Scubapro system costs about $50 more but comes with the reputation and service network of a major manufacturer.

Compared to premium systems like the MK25 EVO/S620 Ti ($1,249), you give up some breathing performance and the titanium components. For recreational diving within sport limits, the MK11 EVO/C370 performs well enough that most divers won’t notice the difference. The premium systems make more sense for professional use or technical diving.

Our Professional Opinion

The main strength is value for money. This regulator delivers solid Scubapro quality and reliable performance for less than $700. The compact design and lightweight construction make it good for travel. The cold water certification gives confidence for diving in varying conditions.

The limitation is breathing performance compared to higher-end models. The MK11 EVO/C370 breathes well for recreational diving, but you’ll feel the difference if you dive deep or work hard underwater. The plastic bumpers on the first stage are practical but don’t feel as premium as all-metal construction.

Final Recommendation

Buy the MK11 EVO/C370 if you want dependable Scubapro quality for recreational diving without paying premium prices. This regulator suits vacation divers, new divers buying their first equipment, and recreational divers who stay within sport limits. The compact design makes it particularly good for traveling divers who want something reliable and easy to pack.

Skip it if you frequently dive deep, plan to advance into technical diving, or want the absolute best breathing performance. The MK11 EVO/C370 works well within its designed scope, but divers with more demanding requirements should consider higher-end options.
