Scubapro MK25 Evo A700 S270 Set regulator
Scubapro MK25 Evo A700
With the Scubapro MK25 Evo A700 Regulator you are guaranteed a reliable, low-effort delivery of air, no matter how hard you're breathing, how deep you're diving, or what your temperature gauge reads.
The MK25 EVO first stage lets you enjoy an ultra-fast breathing response, instant delivery of air on demand, great sensitivity and extra-high airflow -- regardless of how cold the water is. This is made possible with SCUBAPRO's exclusive patented Extended Thermal Insulating System (XTIS) that fully isolates the mechanical elements of the first stage from the cold, increasing its freezing resistance 30 percent over previous versions of the MK25 without compromising breathing performance. This makes the MK25 EVO the ultimate do-it-all first stage for all water temperatures.
The A700 second stage, with its metal casing, screw-down casing cover, metal valve housing (barrel) and over-molded accents, exhibits a real muscularity in design. Its air-balanced valve technology and oversized exhaust valve work in conjunction with a well designed sectional exhaust tee, a first-rate purge and responsive user controls to create a bullet-proof breather with effortless inhalation and an ease of exhalation that is unmatched.
Put these two stellar stages together and you get unparalleled breathing performance whether you're cruising the balmy waters of Bonaire or venturing beneath a polar ice cap.
Wherever the adventure takes you, when you go with the Scubapro MK25 Evo A700 Regulator, you go with the best.
MK25 EVO First Stage:
- Air balanced flow-through piston in a chrome-plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
- Patented XTIS (Extended Thermal Insulating System) fully isolates the mechanical elements from the cold, increasing freezing resistance 30 percent over the previous MK25 without compromising breathing performance. Key insulation system components are visible in blue.
- New spring insulating coating, body insulating bushing, anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water performance.
- 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 low pressure ports on a swivel turret maximize hose routing options.
- External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
- Available in either 3364psi/232bar INT or 4350psi/300bar DIN configurations.
- Weight: INT 232 (oz/g): 27.9/790; DIN 300 (oz/g): 20.1/572.
- Airflow at 2900psi/200bar: (l/min/SCFM): >8500/301.
- Intermediate pressure (psi/bar): 133-142/9.2-9.8.
A700 Second Stage:
- Rugged full metal case and valve housing (barrel) are able to withstand years of aggressive diving.
- Metal construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity.
- Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
- User controls include a diver-adjustable inhalation effort knob and coaxial-flow Venturi-Initiated Vacuum Assist (VIVA) lever.
- Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
- Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.
- Weight (without mouthpiece): 9.2oz/261g.
- Airflow at 2900psi: 2000 l/min - 71 SCFM.

Product description
The S270 Octopus is tough, reliable, and easy to use. Its air-balanced design can be counted on to deliver top-notch breathing performance when you need it most.
- Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
- Lightweight casing, made of a fiberglass-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 extreme cold water.
- Dive/predive switch prevents freeflows when not being used.
- Compact and efficient exhaust tee minimises exhalation effort.
- 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.
- 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.
