Scubapro MK25 EVO/G260 Regulator

The MK25 EVO/G260 system from SCUBAPRO is the perfect choice for recreational and technical divers seeking reliable performance on any dive, anywhere in the world. The MK25 EVO first stage boasts an ultra-fast breathing response, exceptional sensitivity, and high airflow, making it ideal for all water temperatures. The G260 second stage is the most imitated air balanced model ever produced, featuring durable metal internal components and a left-right hose attachment option. Its exceptional performance makes it a top-of-the-line choice for tech diving configurations. Together, these components deliver rock-solid performance and reliability, ensuring a safe and enjoyable diving experience.

First Stage Features:

• Air balanced flow-through piston in a chrome-plated brass body provides constant and effortless airflow unaffected by 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.

Second Stage Features:

• Rugged reinforced technopolymer design features SCUBAPRO's largest second stage casing and diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.
• Metal components (inlet tube, orifice, inhalation control knob and hose connector) increase resistance to freezing when diving in extreme conditions.
• A diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions and personal tastes, and a Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch prevents free flows in cold water or when used as an octopus.
• High-flow exhaust valve reduces exhalation for better overall breathing comfort, and the reversible hose attachment allows you to easily adjust hose routing for tech diving configurations.
• Super-flow hose features an oversized bore that allows more air to flow on each inhalation.

The Scubapro MK25 EVO and G260 combo provides an ultra-high airflow system for peak performance in all temperatures and diving conditions. As a leader in piston-controlled first stages, Scubapro's MK25 EVO continues this legacy with patented features for unmatched performance. Its balanced piston first stage ensures ultra-stable intermediate pressure for consistently high air delivery, allowing carefree dives at any tank pressure and water temperature.

The air balanced, flow-through piston first stage delivers more air to the second stage, unaffected by changing tank pressures. This design allows lighter, more sensitive components for ultra-fast breathing response and high airflow, especially in low tank pressure ranges. This makes it ideal for demanding sport divers and professionals in both warm and cold-water environments.

The MK25 EVO features two 7/16" threaded opposite high-pressure ports for flexible hose arrangement, enhancing diving comfort. With five 3/8" threaded high flow low-pressure ports on a swiveling turret, it allows 360 Degree hose swivel for ultimate freedom. Authorized Scubapro technicians can easily fine-tune the first stage after maintenance without disassembly.

Cold water diving requires resistance to freezing. The MK25 EVO uses Scubapro's Extended Thermal Insulating System (XTIS) to meet EN250-2014 cold water diving requirements. It surpasses these standards, increasing freezing resistance by 30% over previous models. New design features include a proprietary thermal insulating coating, encapsulating main spring bushing, and patented finned cap with body fins for optimal cold-water diving.

This system offers cold-water performance equal to Scubapro's MK17 first stage. The MK25 EVO is made from marine-grade chrome plated brass, demonstrating Scubapro's commitment to quality. The G260 balanced adjustable second stage features metal components for excellent cold-water resistance, making it a top choice for demanding divers. With a high flow exhaust valve and orthodontic mouthpiece, the regulator ensures optimal breathing comfort in any condition. Weighing 38.8 oz (1,100 g), the regulator comes with an owner's manual.
