MK25 EVO/A700 Dive Regulator System

Overview
With the MK25 EVO/A700 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. The A700 second stage, with its metal casing, screw-down cover, metal valve housing (barrel) and over-molded accents, exhibits a real muscularity in design. Put them together and you get unparalleled breathing performance whether you're cruising the balmy waters of the tropics or venturing beneath a polar ice cap.
FEATURES
- Air balanced piston first stage in a chrome-plated body delivers consistent and effortless airflow, regardless of depth, tank pressure, or breathing rate.
- Patented XTIS (Extended thermal Insulating system) thermally insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in extreme cold-water conditions without compromising breathing 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.
- Four high-flow and one axial super 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.
- Rugged full metal second stage case and valve housing (barrel) are able to withstand years of aggressive diving.
- Metal second stage case construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity.
- Air balanced second stage valve smooths out the inhalation effort when diving at varying depths and supply pressures.
- Sectional exhaust tee and a first-rate purge help to deliver effortless inhalation and an ease of exhalation that is unmatched.
- User controls include a diver-adjustable inhalation effort knob and coaxial Venturi-Initiated Vacuum Assist (VIVA) switch.
- Super-flow hose features an oversized bore that allows more air to flow on each inhalation.

Frequently Asked Questions
FAQs
What is the SCUBAPRO Regulator Event?
Purchase a qualifying regulator system and receive a free R105 Octopus. See full terms and conditions.
Qualifying Regulators: MK17 EVO 2/S620 Ti, MK25 EVO/S620 Ti, MK17 EVO 2/G260, MK19 EVO/G260, MK25 EVO/G260, MK19 EVO/A700, MK25 EVO/A700, MK25 EVO/S600. The R105 Octopus will automatically get added to the shopping cart when a qualifying regulator system is added.
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.
