- Delivery & Returns
The Scubapro MK25 EVO D420 Regulator is the latest iteration of the high performing D-Series design that offers near-natural breathing, incredible flow rates, smooth delivery and an ambidextrous design that allows a certified technician to change the handing from right to left for alternative hose routing options.
SPECIAL OFFER: For a limited time only get a FREE Scubapro R195 Octopus worth £175 (RRP) when you purchase this regulator. Valid until 31st July 2022 and subject to stock availability!
The MK25 EVO first stage is used in all of Scubapro's top-performing regulators. Its high performance balanced piston design delivers serious flow rates to four pressure ports around the edge of a swivelling turret and a fifth direct flow port on the end of the turret that delivers the best flow efficiency for maximum performance. To combat extreme cold conditions and ice crystal build-up in the MK25 EVO, Scubapro thermally insulates internal components that come into contact with the water, utilising a special coating that increases cold-water resistance by 30% without compromising performance.
The D420 second stage has an entirely new balanced valve design within a fibreglass-reinforced nylon casing that is exceptionally durable. The unique shape of the second stage and internal valve allows the second stage to be converted from right to left handing by a qualified technician, making the D420 a perfect regulator for any divers that wants a left hose routed regulator for their kit configuration.
The new valve is called the Progressive Flow Control Valve, and it is able to deliver abundant airflow for the best breathing performance, with a natural smoothness comparable to what you might experience breathing on the surface. A new dive/pre-dive system includes a switch on the top of the casing with a thumb tab for adjusting the direction of airflow right out of the valve.

- Air balanced flow-through piston design delivers consistent and effortless airflow, regardless of depth, tank pressure, or breathing rate.
- Patented XTIS (Extended Thermal Insulating System) fully insulates the inner mechanism from the environment, improving cold-water resistance by 30% and delaying ice formation in extreme cold-water conditions without compromising breathing performance. Key insulation system components are visible in blue.
- Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.
- Two opposing high-pressure ports allow the first stage to be positioned either up or down.
- Five high-flow and one axial super high-flow low-pressure ports on a swivel turret maximise hose routing options.
- External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
