The MK25 EVO, paired with Scubapro's exceptional A700 Carbon Black Tech, offers a superior ultra-high airflow system for peak performance in all diving conditions. As a leader in piston-controlled first stages, Scubapro's MK25 EVO continues this legacy with patented features that guarantee unfailing performance. Its balanced piston design ensures instant airflow at any tank pressure and water temperature for worry-free dives.

Air balanced flow-thru piston first stages deliver more air to the second stage than others, while remaining unaffected by changing tank pressure. A balanced piston allows lighter, more sensitive components, providing ultra-fast breathing response, instant air delivery, and high air flow, particularly at low tank pressures. This offers tired divers smoother breathing during ascents or deco stops, making balanced piston first stages the top choice for demanding sport divers and professionals.

The MK25 EVO features two opposite high-pressure ports (HP) for individual positioning of the first stage, increasing head and neck movement freedom. It also has five high flow (HF) low-pressure ports on a swiveling turret for a 360-degree hose swivel. Scubapro technicians can externally adjust the intermediate pressure without disassembly.

The MK25 EVO regulator's Extended Thermal Insulating System (XTIS) offers superior cold-water performance, equal to Scubapro's MK17 first stage. With enhanced freezing resistance, it's perfect for divers demanding high performance in cold environments. The MK25 EVO/A700, made from marine-grade brass with a polished, chemical nickel-coated, and PVD-plated black finish, showcases Scubapro's commitment to quality.

Scubapro's A700 Carbon Black Tech second stage, featuring a full metal housing and carbon fiber front cover, offers extraordinary breathing performance and durability. Its air-balanced valve technology ensures minimal inhalation effort and a high-flow exhaust valve for easy breathing at any depth or condition. Equipped with a diver-adjustable inhalation knob and Venturi Initiated Vacuum Assist (VIVA), the A700 Carbon Black Tech provides a comfortable, efficient diving experience.

• Handmade carbon fiber front cover, metal casing and metal valve housing (barrel) make for a rugged second stage able to withstand years of aggressive diving.

• Carbon fiber is extremely lightweight and, unlike metal that can change shape when dropped or struck against a hard object, carbon fiber can resist substantial shocks without damage.

• Metal case construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity.

• DLC Black Tech coating protects from corrosion and scratches and lends a technical look to the regulator.

• Air balanced second stage smooths out the inhalation effort when diving at varying depths and supply pressures.

• User controls include a diver-adjustable inhalation effort knob and coaxial Venturi-Initiated Vacuum Assist (VIVA) switch.

• Air balanced piston first stage in a Black Tech-coated brass body delivers consistent and effortless airflow, regardless of depth, tank pressure, or breathing rate.

• With its patented ultra-freeze-resistant Extended Thermal Insulating System (XTIS) the MK25 EVO offers excellent thermal insulation by fully isolating the mechanical elements of the first stage from the cold, all 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.
