The new Scubapro MK17 EVO 2 and MK11 EVO C370 regulator systems have arrived at Mike's Dive Store, and they're worth a close look. Whether you're diving the UK's cold, murky depths or jetting off to warmer waters, there's a setup here built for you. Add in Scubapro's new interchangeable colour frames for the C370 second stage, and you've got a rig that performs and looks the part.
Two First Stages, One Excellent Second Stage
Both systems are built around the C370 second stage, a balanced, adjustable second stage that delivers smooth, effortless breathing across a wide range of conditions. The difference lies in the first stage, and that's where you choose your diving style.

The MK17 EVO 2 + C370: Built for UK Waters
If you're diving in the UK, quarries, wrecks, the English Channel, the MK17 EVO 2 + C370 is the one to reach for. Its environmentally sealed diaphragm design keeps saltwater, silt, and contaminants away from the internal mechanism, which is critical when you're diving in cold, particulate-heavy water. It's also available in a sleek Graphite finish, or as a full colour regulator package if you want to go straight in with a personalised setup.
Why it matters for UK divers:
- Environmentally sealed against cold water and contaminants
- Consistent intermediate pressure even in demanding conditions
- Robust construction built for repeated use in harsh environments
- Ideal for drysuit diving, where reliable airflow at depth matters most
The MK11 EVO + C370: Your Travel-Ready Companion
The MK11 EVO + C370 is Scubapro's answer to the diver who wants quality without the bulk. It's lighter and more compact than the MK17, making it the go-to choice for liveaboards, dive holidays, and recreational divers who don't need the full cold-water spec. If you prefer a distinctive look straight out of the box, it's also available in White or Graphite, or as a complete colour regulator package with octopus, gauges, and BCD hose included.
Why it works for recreational and travel divers:
- Lightweight and compact, fits neatly in a reg bag
- Diaphragm design still offers solid performance in temperate water
- Smooth C370 second stage breathing regardless of depth
- A great entry point into mid-range Scubapro performance
The C370 Second Stage: Why It's the Heart of Both Systems
The C370 is a downstream, balanced second stage, which means it delivers consistent airflow regardless of tank pressure or depth. It features an adjustable inhalation effort dial, letting you fine-tune breathing resistance to suit your style and conditions.
- Balanced design: breathing stays smooth as your tank empties
- Adjustable inhalation effort: dial it in for your comfort level
- Purge button: easy to clear in low visibility
- Venturi switch: reduces freeflow risk on the surface
- Compact and lightweight: comfortable in the mouth on long dives
Personalise Your Reg: C370 Interchangeable Colour Frames
One of the most talked-about additions to the C370 range is the ability to swap out the front cover with a coloured frame, no tools required. It's a small change that makes a real difference.
Why the colour frame upgrade is worth it:
- Instant identification: spot your reg in a kit pile or on a boat deck at a glance
- Buddy identification underwater: useful in group diving and training scenarios
- Match your kit: coordinate with your BCD, fins, or wetsuit colour
- Express your style: because your gear should feel like yours
- Easy to swap: change the look without changing the reg
The frames are available in multiple colours and are compatible across the C370 range, whether you're running an MK17 or MK11 first stage. It's the kind of upgrade that costs very little but adds a lot of personality to your setup.
When Should You Use Each Regulator?
Choose the MK17 EVO 2 + C370 if you:
- Dive UK sites regularly: wrecks, reefs, quarries, or the Channel
- Dive in water below 10°C
- Use a drysuit and need reliable airflow at depth
- Want maximum protection against saltwater ingress and contamination
- Are looking for a long-term workhorse reg that can handle demanding conditions
Choose the MK11 EVO + C370 if you:
- Primarily dive recreationally in temperate or warm water
- Travel frequently and want a lighter kit bag
- Are buying your first mid-range regulator and want quality without over-speccing
- Dive in the UK occasionally but also holiday dive in the Med or tropics
- Want a compact, reliable setup that doesn't compromise on breathing performance
How Do They Compare to Other Scubapro Regulators?
The MK17 EVO 2 and MK11 EVO sit in Scubapro's mid-range, above entry-level systems like the MK2 EVO but below the flagship MK25 EVO and MK19 EVO range. That positioning is intentional: you get genuine performance and durability without paying for features most recreational divers won't need.
- vs. MK2 EVO: better breathing performance, more ports, improved cold-water capability
- vs. MK25 EVO: simpler, lighter, more affordable; the MK25 is for technical and demanding cold-water use
- vs. MK19 EVO: the MK17 is the sealed cold-water alternative; the MK19 is piston-based
Common Questions
Are these suitable for cold water diving?
The MK17 EVO 2 is specifically designed for cold water. Its environmental seal protects against freezing and contamination. The MK11 EVO is suitable for temperate water but is not environmentally sealed, so it's better suited to warmer or milder conditions.
Can I travel with these regulators?
Yes, both travel well. The MK11 EVO is particularly compact and lightweight, making it the better choice if you're packing light for a liveaboard or dive holiday.
Are the colour frames easy to fit?
Yes, the C370 colour frames are designed to clip on and off without tools. It takes seconds and doesn't affect the regulator's performance or warranty.
Do these regulators need specialist servicing?
Scubapro recommends annual servicing or after every 100 dives, whichever comes first. Our team can advise on servicing options. Get in touch if you'd like to know more.
