The Scubapro MK25 EVO / A700 INT dive regulator system with R105 Octopus combines a high-flow balanced piston first stage with a fully metal, air-balanced second stage designed for smooth and consistent breathing performance. This scuba regulator system is engineered for stability across varying depths and temperatures, supporting reliable airflow delivery for recreational, advanced, and technical diving conditions.

The MK25 EVO first stage is built from chrome-plated marine brass and features Scubapro’s Extended Thermal Insulating System (XTIS) to improve resistance to freezing in cold water environments. Its swivel turret and multiple low-pressure and high-pressure ports allow optimized hose routing for streamlined configurations. The A700 second stage is constructed entirely from metal, enhancing durability and heat exchange while providing a stable breathing experience with reduced inhalation effort. Its air-balanced valve system ensures consistent performance under changing pressure conditions. The included R105 Octopus offers a simple and reliable downstream valve design with a high-visibility cover for quick identification as an alternate air source.
