Choosing the right regulator for cold water diving is one of the most important equipment decisions you’ll make. In colder conditions, regulators are pushed harder — dense air, freezing temperatures and demanding dive profiles all increase the risk of free-flows and inconsistent performance if your setup isn’t up to the task.
Scubapro has long been one of the most trusted names for cold and temperate water diving, with regulators designed specifically to handle UK conditions, quarry dives, winter sea temperatures and year-round use. From premium, top-end systems to lighter all-round and travel-friendly options, there’s a Scubapro regulator for almost every type of diver.
This guide breaks down the best Scubapro cold water regulators into three clear categories:
- Premium performance
- Balanced all-rounders
- Lightweight & travel-friendly
We’ll explain who each category is best for, what makes them suitable for cold water, and how to choose the right setup for your diving.
What Makes a Regulator Suitable for Cold Water?
Before diving into specific models, it’s worth understanding what actually matters for cold water performance.
A cold-water-ready regulator typically features:
- Environmental sealing to protect internal components from freezing
- Effective heat exchange to reduce ice formation
- Balanced designs for consistent breathing at depth and varying tank pressures
- Robust materials that cope with repeated cold exposure and long-term use
All regulators in this guide meet recognised cold-water standards and are suitable for UK diving when correctly serviced and configured.
Premium Cold Water Regulators
Best for: experienced divers, frequent cold-water diving, demanding conditions
Premium Scubapro regulator systems are built for divers who want the absolute best breathing performance, reliability and longevity. These setups excel in cold, deep or technical environments and are often chosen by instructors, photographers and technical divers.
Why choose a premium setup?
- Exceptionally smooth breathing, even at depth
- High resistance to freezing and free-flows
- Metal components improve durability and heat transfer
- Designed for intensive, long-term use
Typical premium Scubapro combinations pair a high-performance first stage with an adjustable second stage, giving you maximum control over airflow and inhalation effort.
If you dive regularly in cold UK waters or want a regulator that will last for many years without compromise, this category is worth the investment.
Scubapro MK25T EVO / S620 X-Ti Regulator
This setup represents the most refined and performance-driven regulator system in Scubapro’s lineup, built for divers who want uncompromising breathing performance paired with premium materials. The MK25 EVO first stage is an air-balanced piston design renowned for delivering exceptionally high airflow with virtually no breathing resistance, even under heavy demand. Its XTIS (Extended Thermal Insulating System) significantly improves cold-water resistance by thermally isolating internal components, allowing the regulator to maintain smooth, consistent performance while remaining fully EN250A certified for extreme cold water.
The premium character of this system really comes through in the S620 X-Ti second stage. Titanium is used in key components to reduce weight, increase corrosion resistance and improve long-term durability, while also contributing to excellent thermal behaviour in cold water. Combined with a balanced valve, adjustable inhalation effort and Venturi control, the result is an exceptionally responsive, effortless breathing experience that remains stable at depth and during high gas demand. While some expedition or ice divers may still favour sealed diaphragm designs for the most extreme conditions, the MK25T EVO / S620 X-Ti stands as a true flagship regulator — ideal for experienced divers who want the smoothest possible breathing feel, premium materials and confidence across cold UK diving and worldwide travel alike.
Scubapro MK19 EVO / G260 Carbon Black Tech Regulator
This regulator is built unapologetically for demanding cold-water, technical and overhead environments, where durability and environmental sealing matter just as much as breathing performance. The MK19 EVO is a sealed, balanced diaphragm first stage designed specifically to isolate internal components from cold, silt and contaminants, making it one of Scubapro’s most trusted platforms for serious cold-water diving. Its compact design and swivel turret also make it highly adaptable for sidemount, twinset or stage configurations.
The G260 Carbon Black Tech second stage adds another layer of robustness and thermal efficiency. Internal metal components improve heat exchange to resist freezing, while the carbon fibre front cover and DLC Black Tech coating deliver outstanding impact resistance and corrosion protection. Breathing remains smooth and consistent regardless of depth or tank pressure, but this setup clearly prioritises reliability under stress over ultra-lightweight minimalism. It is an ideal choice for divers who regularly dive cold, deep or low-visibility environments and want a regulator that thrives under abuse rather than simply tolerates it.
Scubapro MK19 EVO / A700 Regulator
This system sits firmly in the “buy once, buy right” category for cold-water divers who want maximum reliability with no compromises. The MK19 EVO provides excellent freeze resistance through its environmentally sealed diaphragm design and dry chamber, making it particularly well suited to near-freezing temperatures, silty sites and repeated cold dives. Its swivel turret and five LP ports allow clean, flexible hose routing even in complex technical setups.
The A700 second stage is where this regulator truly separates itself. Built entirely from metal, it acts as a natural heat sink, transferring ambient warmth to internal components to reduce ice formation during high gas demand. Combined with an exceptionally low work of breathing, the A700 delivers smooth, controlled airflow even in demanding conditions. This pairing is less about weight savings or travel convenience and more about absolute confidence and longevity. For divers who regularly face cold, deep or challenging environments and want the most mechanically robust option in Scubapro’s range, the MK19 EVO / A700 is one of the strongest choices available.
Balanced All-Rounders
Best for: most recreational divers, UK diving + travel, great value

This is one of the most confidence-inspiring all-round cold-water setups in the Scubapro range, particularly for divers who regularly encounter challenging conditions. The MK19 EVO combines full environmental sealing with a swivel turret, delivering excellent freeze resistance alongside flexible hose routing. This makes it suitable not only for recreational cold-water diving, but also for more advanced configurations such as twinsets or sidemount, without committing fully to a dedicated technical-only system.
The G260 second stage reinforces its all-round credentials through durability and adaptability. Internal metal components improve thermal performance in cold water, while its balanced design ensures stable, low-effort breathing across depths and tank pressures. By omitting premium Carbon Black Tech coatings found on its sibling, this setup brings the price point down while retaining the same proven breathing performance and cold-water capability. Slightly larger than pure travel regulators, the G260 prioritises reliability and longevity, making this pairing ideal for divers who want high-end performance in cold, silty UK conditions without paying for materials they don’t necessarily need.
Scubapro MK17 EVO 2 / G260 Regulator Set
This configuration leans firmly toward practicality and long-term reliability. The MK17 EVO 2 provides the same sealed diaphragm performance that makes it well suited to cold and silty conditions, while its compact design keeps it manageable for travel and everyday use. By omitting swivel turrets and premium coatings, it keeps things mechanically simple, which many divers value for regular, repetitive diving.
Matched with the G260 second stage, this setup gains excellent cold-water breathing performance and ruggedness without drifting into premium pricing. The metal internal components of the G260 help resist freezing, while its adjustable controls allow the diver to fine-tune breathing resistance. This pairing is particularly well suited to divers who spend a lot of time in UK waters and want a dependable, no-nonsense system that performs consistently dive after dive.
Scubapro MK17 EVO 2 / S600 Regulator Set
This is a classic all-round regulator choice for divers who value proven design and reliability over added complexity.

By stepping away from titanium components rather than core performance features, this pairing maintains excellent cold-water capability and long-term durability. It is an ideal choice for divers who want a regulator that simply works everywhere, without paying extra for premium materials they may not actually need.
Lightweight & Travel-Friendly
Best for: travelling divers, occasional cold-water use, lighter kit setups
If weight, packability and ease of travel matter, Scubapro’s lighter regulator systems are a strong option — even for cooler water diving.
Key benefits:
- Compact and lightweight designs
- Still suitable for cooler UK conditions
- Lower cost of entry
- Easy to service and maintain
These setups are ideal for:
- Divers who mainly travel but still dive in the UK occasionally
- Those building a lighter kit for flights
- Newer divers wanting a dependable cold-capable regulator without over-spending
While they may not have the same refinement as premium systems, they remain dependable, well-engineered and practical.
Scubapro MK25 EVO / S620Ti Regulator
This is the go-to choice for divers who want a lighter travel setup but still crave that flagship Scubapro breathing feel. Compared to sealed options like the MK19 EVO, the MK25 EVO is noticeably lighter while still offering premium hose routing thanks to its swivel turret and high-flow port layout. Its balanced piston design delivers effortless, high-airflow breathing, and the XTIS thermal insulation system boosts freeze resistance far beyond what most divers expect from a non-sealed first stage. In real terms, it performs beautifully in temperate and cold water and is absolutely capable for occasional UK cold-water diving, provided you’re not regularly diving in silty or contaminated environments where sealing becomes a priority.
The S620 Ti keeps the whole system feeling “premium-light” rather than just “light”. Titanium components reduce weight and improve corrosion resistance, helping minimise jaw fatigue on longer dives and making it ideal for frequent travel. Breathing performance remains top-tier, with excellent sensitivity and control across depths. This pairing makes sense for divers who don’t need a sealed design, dive mainly clean environments, and want maximum breathing quality and hose-routing flexibility in a streamlined, travel-friendly package.
Scubapro MK17 EVO 2 / C370 Regulator
This is one of the smartest travel-friendly setups for divers who still want genuine cold-water confidence. The MK17 EVO 2 is a sealed balanced diaphragm first stage, which means it’s far better protected from cold, silt and general “messy” environments than non-sealed travel regs. The EVO 2 design also keeps it compact and practical to pack, so you’re not choosing between travel convenience and cold-water reliability — you get a proper cold-water platform that still makes sense in a luggage-friendly kit.
Paired with the C370, the focus is on sensible performance in a lighter, simpler second stage rather than premium materials. You still get smooth, predictable breathing with user-friendly controls, but without paying for titanium, carbon or full-metal construction. That’s exactly why it’s such a strong all-round travel option: it keeps the price more approachable, keeps the kit lighter, and still gives you a setup you can confidently take from warm-water trips to occasional UK cold-water dives without feeling under-gunned.
Scubapro MK11 EVO / S270 Regulator
This is the “easy win” option for divers who prioritise compactness, value and travel convenience, but still want legitimate cold-water certification in their back pocket. The MK11 EVO uses a balanced diaphragm design in a compact body, and crucially it remains EN250A certified for all diving conditions including extreme cold water — which is a big deal at this price point. It’s not trying to be a high-performance flagship first stage; instead it’s designed to be efficient, reliable and simple, especially for recreational travel diving.
The S270 second stage complements that philosophy perfectly: dependable breathing performance, lightweight build and a no-drama feel in the water. By skipping premium materials and top-end “tech finish” extras, this setup keeps the cost down while still offering proper capability for occasional cold-water use. It’s ideal for travellers who mainly dive warm water but want the reassurance that their regulator can handle a UK trip here and there — without stepping up into heavier, more expensive systems.
