Part: 12.252.030 Item Includes1'st Stage - 2'nd Stage Regulator - LP Hose - Read First Manual - MFG Lifetime Limited Warranty DescriptionThe MK25 DIN teamed Scubapro's G260, offers superior ultra-high airflow system for maximum performance in all temperatures and diving conditions. Scubapro has been the leader in the evolution of piston controlled first stages since its beginning; the MK25 DIN carries on this heritage with an array of patented features ensuring unfailing performance. The MK25 DIN is a balanced piston first stage, Scubapro's absolute top performer. It is a superior regulator thanks to its ultra-stable intermediate pressure (IP) resulting in an extremely-punctual and constantly high delivery of air. This means instant airflow at any tank pressure and water temperature for a real carefree dive. Air Balanced, Flow-Thru-Piston First Stage: Air balanced pistons deliver significantly more air to the second stage than any other first stage, while their performance is totally unaffected by the changing tank pressure. A balanced piston allows the use of lighter and more sensitive components, resulting in ultra-fast breathing response, instant delivery of air on demand, and extra high air flow, especially in low tank pressure ranges. The tired diver benefits from a smoother breathing regulator during the ascent or deco stop. Balanced piston first stages are the first choice of demanding sport divers and professionals. A balanced piston performs equally in warm and cold-water environments. The MK25 DIN has two opposite 7/16" threaded high-pressure ports (HP). The arrangement of high-and-low-pressure hoses is crucial to diving comfort. Two opposite HP ports allow for an individual positioning of the first stage (pointing up or down). This allows the diver to position the gauges either on the right or left side and increases the freedom of movement for head and neck. Multiple 3/8" threaded low-pressure ports (LP) - For ultimate freedom in the arrangement of LP hoses, the MK25 DIN accommodates five HF (High Flow) ports on a swiveling turret, which allows for 360-degree swivel of hoses. High flow ports deliver about 15% more air than conventional ports. Externally adjustable intermediate pressure- allows authorized Scubapro service technicians to quickly fine-tune and adjusts the first stage after maintenance without the need to disassemble it. Cold Water Diving conditions can be drastically different, including extreme cold water and outside temperatures, posing the possibility of a regulator freezing. Therefore, resistance to freezing is imperative for the diver. The MK25 DIN regulator uses Scubapro's new Extended Thermal Insulating System (XTIS). The Scubapro MK25 EVO DIN first stage regulator meets the new EN250-2014 requirements for cold water diving, CE approved for 4350 psi (300 bars). This model goes even beyond this super stringent qualification and has successfully been tested in extreme cold diving conditions at less than 36-degree F (2.2-degree C). The freezing resistance has been increased by 30% over the previous MK25 regulator first stage. Scubapro has achieved this with some new design features. The new MK25 EVO DIN has a proprietary thermal insulating coating on key internal components and an encapsulating main spring bushing that resist the cooling effect in previous MK25 first stage regulators, also as a specific anti-freezing measure; Scubapro engineers have designed a patented finned cap with additional body fins for the MK25 EVO DIN first stages for optimal-cold water diving. The fins (ribs) of the XTIS act as a radiator to increase the surface area of heat transfer from the water to warm up the internal parts that have been drastically cooled down by the gas pressure drop. The new MK25 EVO DIN has a bigger body cap, new body with insulating bushing and ribs, new antifreeze cap patented isolation system with all internal parts fully insulated to dramatically improve cold water performance. This system now gives the diver superior cold-water performance, equal to that of Scubapro's MK17 first stage. Now you have the option of a high-performance flow through piston design, with a high level of performance in cold water. This is the answer for those divers who demand a high level of performance for cold water environments. The MK25 EVO DIN is manufactured from marine grade chrome plated brass and offers a balanced composite/stainless steel flow-thru piston that would make any diver proud. It demonstrates Scubapro's dedication to quality and creating positive diving experiences. The G260 is a balanced adjustable second stage featuring metal components for excellent cold-water resistance (inlet tube, orifice, inhalation control knob and hose connector). Its high performance makes it a choice for all demanding divers and it will be the natural choice for G250 fans. The new left-right hose attachment option makes it ideally suited for tech diving configurations. The G260 air balanced flow valve is made from durable corrosion resistant chrome plated brass. The regulator has a diver adjustable inhalation effort that allows personalized breathing control and a Venturi initiated vacuum assist (VIVA) to prevent free Flow in cold water. The G260 is equipped with a high flow exhaust valve that reduces exhalation effort for better breathing comfort. Regulator also has a high comfort orthodontic mouthpiece. The Regulator comes equipped with a 3/8" threaded super-flow hose for smooth air delivery. Precision molded, lightweight components and anti-freeze materials provide high corrosion resistance and enhance cold water performance. The second stage is equipped with a comfortable orthodontic mouthpiece. All these features produce the highest performance in any conditions. The regulator weighs 30.6 oz (867g) and comes with an read first manual.FeaturesMK25/G260 Regulator, DIN:High Performance, Reliable Scubapro Technology & ValueSuperior Ultra-High Airflow SystemMaximum Performance In-All-Temperatures & ConditionsWeight: 30.6 oz (867g)3/8" Threaded Low Pressure Super Flow HoseRead First ManualFirst Stage:Scubapro MK25Ultra-Stable Intermediate PressureHigh Performance in Warm & Cold Water to 4300 psi (300 bars)Air-Balanced Flow-Through Piston DesignBalanced Composite/Stainless Steel Flow-Thru PistonThermal Insulating System (TIS)TIS: Prevents Freezing-Up & Malfunctioning In-Cold-Water-ConditionsHP 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 G260 RegulatorBalanced Adjustable Second StageMetal Components for Excellent Cold-Water ResistanceLeft-Right Hose Attachment OptionDurable Corrosion Resistant Chrome Plated Brass Valve AssemblyDiver Adjustable Inhalation Effort for Personalized Breathing ControlVenturi Initiated Vacuum Assist (VIVA)VIVA: Prevents Free Flow in Cold WaterHigh Flow Exhaust Valve that Reduces Exhalation EffortHigh Comfort Orthodontic MouthpieceHighest Performance In-Any-ConditionsSpecifications1'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: Components & Valve Housing: Chromed BrassHose Thread3/8"Total Weight30.6 oz (867g) Feedback is a very powerful tool.
