The MK19 EVO/G260 regulator delivers dependable air delivery in cold, deep, and silty dives. This compact, sealed system from Scubapro is built to withstand harsh underwater conditions and is trusted by scuba divers, tech divers, and cave explorers alike. The first stage features a diaphragm design with chrome-plated brass construction, paired with a versatile left-right hose attachment for flexible configurations.

Designed for challenging underwater environments, the G Series second stage uses metal components and an air-balanced valve for smooth, consistent performance. Features such as the Diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) switch support reliable breathing in cold water, while the high-flow exhaust valve helps manage exhaust in submerged conditions. The system is suitable for Nitrox mixes up to 40% and remains dependable in both exploration and technical diving scenarios.
