Part: 12.770.040 Item Includes1'st Stage - 2'nd Stage Regulator - LP Hose - Read First Manual - MFG Lifetime Limited Warranty DescriptionThe MK25 EVO and A700 combo from Scubapro offers an ultra-high airflow system for peak performance in all diving conditions. As a leader in piston-controlled first stages, Scubapro's MK25 EVO boasts patented features for consistent, reliable performance. The balanced piston first stage ensures stable intermediate pressure, providing instant and constant high air delivery, no matter the tank pressure or water temperature. Air-balanced pistons deliver more air to the second stage and maintain performance even with changing tank pressure. Their design allows for lighter, more sensitive components, resulting in ultra-fast breathing response and high airflow, particularly in low tank pressure ranges. Ideal for demanding sport divers and professionals, the MK25 EVO offers two opposite high-pressure ports (HP) for optimal gauge positioning and five high-flow low-pressure ports (LP) on a swiveling turret for 360-degree hose swivel. Scubapro's Extended Thermal Insulating System (XTIS) ensures reliable performance in extreme cold water conditions. With a 30% increase in freezing resistance over the previous model, the MK25 EVO meets EN250-2014 requirements for cold water diving. Design features such as a thermal insulating coating on internal components, encapsulating main spring bushing, and patented finned cap optimize cold water performance. The A700 second stage is the pinnacle of Scubapro's regulator line, offering extraordinary breathing performance in a handcrafted, full metal design. The compact, air-balanced valve technology ensures minimal inhalation effort and a high-flow exhaust valve for ease of breathing in any diving situation. It also features a diver-adjustable inhalation knob and Venturi Initiated Vacuum Assist (VIVA) for personalized breathing control and free-flow prevention. The MK25/A700 regulator comes with a 3/8" threaded super-flow hose, a high-flow mouthpiece, and a read-first manual. Weighing 38.4 oz (1,090g), this regulator is designed for comfortable, effortless underwater breathing and lasting dive experiences.FeaturesMK25 EVO/A700 Regulator:High Performance, Reliable Scubapro Technology & ValueSuperior Ultra-High Airflow System, Maximum Performance In-All-Temperatures & Conditions1'st & 2'nd Stage Body & Housing: Chromed Plated BrassWeight: 38.4 oz (1,090g)Read First ManualFirst-Stage:Scubapro MK25 EVOSuperior Cold-Water Performance Equal to Scubapro's MK17 First StageEVO: Means Evolution, Revolutionizing Existing Technologies to Higher PerformanceUltra-Stable Intermediate PressureHigh Performance-In Warm & Cold WaterMeets New EN250-2014 RequirementsCE Approved for 3360 psi (230 bars) In-Cold-Water-ConditionsIncreased Cold Water Efficiency by 30% Over Previous MK25 RegulatorNew Design: Proprietary Insulating Coating On-Key Internal Components Specific Anti-Freezing Measure Patented Finned Cap & Body Xtreme Thermal Insulating System (XTIS) Ribs of XTIS: Act as Radiator, Increase Surface Area of Heat Transfer Warms-Up Internal PartsNew Parts: Bigger Body Cap Insulating BushingAntifreeze Cap Patented Isolation System Internal Parts Fully Insulated to Dramatically Improve Cold Water PerformanceAir-Balanced Flow-Thru-Piston DesignBalanced Composite/Stainless Steel Flow-Thru-PistonHP Ports: Two 7/16" ThreadedLP High Flow (HF) Ports: Five 3/8" ThreadedLP Ports Mounted-On Swivel Turret Cap for Maximum Hose RoutingSecond-Stage:Scubapro A700Unparalleled Breathing PerformanceAir Balanced Valve TechnologyDecreased Inhalation ResistanceSuper High-Flow Exhaust ValveCoaxial FlowAdjustable Inhalation EffortDiver-Adjustable Venturi-Initiated Vacuum Assist (VIVA)High Comfort Orthodontic MouthpieceFull Metal CaseFull Metal Valve HousingCompact Dimensions for Lightweight ComfortIncludes Super Flow LP HoseSpecifications1'st Stage TypeBalanced Flow-Thru-PistonLP Ports5-High-Flow 3/8" ThreadedHP PortsTwo-7/16" ThreadedAdjustable 2'nd StageAdjustable Breathing Resistant's Venturi Dive/Pre-Dive SwitchNitrox CompatibleUp to 40% O22'nd Stage TypeAir Balanced ValveMaterialsFirst Stage: Body Chromed Brass Piston: Composite/Stainless Steel Second Stage: Case & Valve Housing: Chromed BrassHose Thread3/8"Total Weight38.4 oz (1,090g) Feedback is a very powerful tool.
