The Scubapro MK25 EVO / S620Ti White regulator system paired with a complimentary R105 Octopus is designed for divers who require consistent breathing performance across varying depths and water temperatures. This balanced piston first stage and titanium second stage combination is engineered for high airflow, corrosion resistance, and dependable operation in both warm and cold water environments. The air-balanced design maintains stable intermediate pressure regardless of tank pressure or depth, supporting smooth inhalation throughout the dive.

The MK25 EVO first stage uses a chrome-plated marine brass body with a patented Extended Thermal Insulating System (XTIS) to improve freeze resistance in cold water. Its rotating swivel turret and multiple high- and low-pressure ports allow clean hose routing for streamlined configurations. Paired with the S620Ti second stage, built with a lightweight titanium barrel and reinforced technopolymer housing, the system reduces jaw fatigue while maintaining rugged durability for frequent diving. The included R105 Octopus provides a reliable, high-visibility alternate air source with classic downstream valve design for simple, dependable performance.
