The MK25 EVO DIN teamed with Scubapro's exceptional A700, 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 EVO DIN carries on this heritage with an array of patented features ensuring unfailing performance. The MK25EVO 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 stages with 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 EVO DIN has two opposite 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 low-pressure ports (LP) - For ultimate freedom in the arrangement of LP hoses, the MK25 EVO DIN accommodates five HF (High Flow) ports on a swiveling turret, which allows for 360° 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 EVO 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 4350psi (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°F (2.2°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.Scubapro has once again raised the bar for regulator performance with the introduction of the A700 second stage. It is truly the crown jewel of the Scubapro regulator line. The A700 delivers extraordinary breathing perforce Scubapro A700 lets you breathe effortlessly and naturally underwater for a lifetime of exceptional dive experiences. 

Small and compact for comfort in diving, this air-balanced valve technology regulator has minimal inhalation effort and super high-flow exhaust valve for ease of inhalation and exhalation at any depth or dive condition. Regulator is equipped with a diver-adjustable inhalation knob for fine tuning of breathing resistant's and diver-adjustable Venturi-Initiated Vacuum Assist (VIVA) for additional inhalation assistance and free-flow prevention. The A700 has a High Comfort Orthodontic Mouthpiece. Built for demanding divers and demanding conditions, the MK17 EVO/A700 is the first stage of choice for harsh environments and cold-water conditions, and ideal for cave and wreck diving. Designed to deliver a smooth and steady supply of air no matter how frigid or murky the water gets, with this regulator system you can always be confident of your next breath. The regulator weighs 30.2 oz. (857 g) and comes with an owner's manual.
