  • The Scubapro MK25 EVO D420/S270 Regulator Set combines the iconic design of the original D-Series regulators with the latest advances in breathing performance technology. SCUBAPRO engineers have created a 21st-century regulator in terms of quality, reliability, performance and style. The D420 features a balanced valve inside a housing supported by a full metal structure. Called the Progressive Flow Control Valve, 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.

    The uniquely shaped fibreglass-reinforced nylon casing is ultra-durable and allows the LP hose to be connected on either the right or left side for maximum rigging flexibility. A dive/pre-dive system includes a switch on the top of the casing with a thumb tab to adjust the airflow direction right out of the valve. The highly efficient purge button is a technical jewel based on a concept that gives the D420 its unique face.

    Teamed with the venerable MK25 EVO balanced piston first stage, this is a regulator system purpose-designed for today’s avid divers and SCUBAPRO brand enthusiasts everywhere.


    VIDEO CONSULTATIONS NOW AVAILABLE: We're bringing our highly experienced and knowledgeable staff to you with live-streaming consultations. If you need help choosing the right bit of kit or the best size before buying or even advice on whether a purchased item is the right fit for you, then book yourself a consultation appointment.


    FIRST STAGE Features:
    • Air-balanced flow-through piston in a chrome-plated marine-grade brass body provides constant and effortless airflow unaffected by 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 up or down.
    • Four high-flow and one axial super high-flow low-pressure port on a swivel turret maximise hose routing options.
    • External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
    • Weight: INT 232, 790g; DIN 300, 572g.
    • Airflow at 2900psi/200bar: (l/min/SCFM): >8500/301.
    • Intermediate pressure (psi/bar): 133-142/9.2-9.8.
    SECOND STAGE Features:
    • Uniquely shaped fibreglass-reinforced nylon casing carries on the D-Series heritage with the latest advances in breathing performance technology.
    • Air-balanced Progressive Flow Control Valve is able to deliver abundant airflow with a natural smoothness comparable to breathing on the surface.
    • Dive/pre-dive system includes a switch on the top of the case with a thumb tab for adjusting the direction of airflow right out of the valve.
    • Casing design features inner winglets that direct airflow towards the exhaust valve, creating a dramatic improvement in exhalation effort.
    • Diaphragm is located in the lower section of the casing to take advantage of the pressure gradient in the upright position, making breathing even easier.
    • Reversible hose attachment allows for either left- or right-side LP hose connections for maximum rigging flexibility.
    • Large purge button is easy to reach and press, with or without gloves.
    • Exhaust tee is compact and efficiently deflects bubbles from the diver’s view while enhancing the ease of exhalation.
    • Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
    • Compact Hi-Flow mouthpiece improves airflow as well as mouth comfort, fitting all mouth sizes, from largest to smallest.
    • CE certified according the latest EN250A European Standards for all diving conditions, including extreme cold water.
    • Weight (without mouthpiece): 216g.
    • Airflow at 200bar: 1800 l/min - 64 SCFM.
    OCTOPUS S270 Features:
    • Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
    • Lightweight casing, made of a fibreglass-reinforced nylon core and a special PU outer layer, is extremely durable plus helps reduce jaw fatigue and improve diving comfort.
    • Technopolymer plastic barrel with a metal thread and a balanced valve helps save weight and provides a surface that ice crystals can’t grab onto when diving in extremely cold water.
    • The dive/predive switch prevents free flows when not being used.
    • The exhaust tee is compact and very efficient in minimising exhalation effort.
    • The compact Hi-Flow mouthpiece is comfortable, made with FDA-approved silicone and features a large cross-section to maximise airflow.
    • High-viz yellow front cover stands out, making it easy to spot when needed.
    • The high-viz yellow super-flow hose is 39in/1m long with an oversized bore that allows more air to flow on each inhalation.
    • CE certified to the latest EN250A European Standards for all diving conditions, including extreme cold water
