Overview
If you dive deep, dive cold, or often find yourself on silty bottoms, the MK19 EVO/G260 is the regulator for you. While you don’t need to dive less-than-pristine waters to appreciate this system, it’s a great choice for cold water or harsh conditions, which is why tech divers and cave explorers just love this reg. The compact MK19 EVO is completely sealed off from the elements, ensuring trouble-free operation no matter how cold or murky the water gets. The G260 is the most imitated air balanced second stage of all time. It features metal internal components and a left-right hose attachment option, making it a great choice for tech diving configurations and a consistent top-of-the-line performer. Put them together and you’ve got a winner.
FEATURES
- Rugged reinforced technopolymer design features SCUBAPRO's largest second stage casing and diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.
- Air balanced second stage valve smooths out the inhalation effort at varying depths and supply pressures.
- A diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions and personal tastes, and a Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch prevents free flows in cold water or when used as an octopus.
- High-flow exhaust valve reduces exhalation for better overall breathing comfort, and the reversible hose attachment allows you to easily adjust hose routing for tech diving configurations.
- Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
- Air-balanced first stage diaphragm delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate
- Environmentally sealed system prevents water and pollutants from fouling the inner mechanism and is extremely resistant to freezing
- Dry chamber is equipped with a double spring making it more compact and reliable.
- Two opposing high pressure ports allow the first stage to be positioned either up or down, plus provide for an optimum hose/transmitter layout
- Swivel turret comes with four High-Flow LP ports plus one axial Super High-Flow LP port to maximize hose routing options for technical diving layouts

What is the best SCUBAPRO regulator for cold water and demanding conditions?
The MK25 EVO/S620 Ti is SCUBAPRO's flagship system for demanding dives. Its full titanium inlet tube resists corrosion, the environmentally sealed first stage prevents freeze-up in cold water, and the S620 Ti second stage delivers effortless airflow at any depth. It is the top choice for performance divers who dive across a wide range of conditions.
Why should I buy a complete regulator system instead of individual components?
A factory-matched regulator system — first stage, second stage, and octopus — is engineered to deliver balanced airflow, consistent intermediate pressure, and reliable performance as a unit. Buying a complete system also simplifies servicing, ensures component compatibility, and during the Regulator Event, includes a free R105 Octopus to round out your setup.
How does SCUBAPRO compare to other regulator brands?
SCUBAPRO regulators are designed, tested, and serviced as complete systems rather than individual components. Key differentiators include environmentally sealed first stages for cold-water reliability, titanium construction for corrosion resistance and reduced weight, and a global authorized service network. The Regulator Event makes it an ideal time to step up from other brands with a complimentary octopus included.
What is the R105 Octopus and why do I need one?
The R105 is SCUBAPRO's dedicated octopus (alternate air source) — a compact, high-visibility second stage designed for emergency air sharing. Every open-water diver needs an octopus as part of a complete regulator system. During the Regulator Event, the R105 is included free with qualifying regulator system purchases, completing your setup at no additional cost.
Do promotional regulators include the same warranty coverage?
All SCUBAPRO regulators are backed by a limited lifetime warranty - see conditions.
