£2,049.00 £2,049.00
The SCUBAPRO MK25 EVO T / S620 X-Ti Regulator System combines a full titanium first stage with a lightweight, high-performance second stage for exceptional breathing performance in all dive conditions. Featuring XTIS cold-water technology, anti-corrosion titanium construction, reduced breathing effort, and advanced airflow design, it delivers reliable and effortless diving performance.
The SCUBAPRO MK25 EVO T / S620 X-Ti Regulator System is designed for divers seeking lightweight construction, corrosion resistance, and premium breathing performance. Combining the titanium MK25 EVO T first stage with the advanced S620 X-Ti second stage, this system provides smooth and effortless airflow in all water temperatures and dive environments.
The MK25 EVO T first stage is precision-machined from a solid titanium block, offering exceptional corrosion resistance even in concentrated saltwater conditions. Its air-balanced flow-through piston delivers constant airflow regardless of depth, tank pressure, or breathing rate. SCUBAPRO’s patented XTIS (Extended Thermal Insulating System) improves cold-water resistance and delays ice formation in extreme conditions.
The S620 X-Ti second stage features a compact and lightweight design while using the same large diaphragm found in the S600 for maximum breathing sensitivity. Work of breathing has been reduced by 37% compared to the S600, delivering smooth and effortless airflow. Titanium components, including the barrel and adjustment rings, help reduce weight while improving durability and corrosion resistance.
