The Scubapro MK25 EVO / G260 dive regulator system with R105 Octopus combines a high-performance balanced piston first stage with a rugged, air-balanced second stage designed for demanding diving conditions. This scuba regulator system delivers consistent airflow and stable intermediate pressure regardless of depth or remaining tank pressure, supporting smooth and reliable breathing in warm or cold water environments. The configuration is widely used for recreational, technical, and cold water diving due to its airflow capacity and durable construction.

The MK25 EVO first stage is manufactured from chrome-plated marine brass and features Scubapro’s Extended Thermal Insulating System (XTIS) to improve freeze resistance in cold water. A rotating swivel turret with multiple low-pressure and high-pressure ports allows flexible hose routing for streamlined setups. The G260 second stage features a metal valve housing and reinforced technopolymer casing, providing durability and enhanced heat exchange. Its air-balanced valve, adjustable inhalation effort knob, and Venturi-Initiated Vacuum Assist (VIVA) control allow divers to fine-tune breathing characteristics. The included R105 Octopus provides a dependable alternate air source with a classic downstream valve design and high-visibility front cover for quick identification.
