Scubapro MK19 EVO/A700 Regulator w/ FREE R105 Octopus

The Scubapro MK19 EVO / A700 regulator system with R105 Octopus pairs a sealed diaphragm first stage with an all-metal, air-balanced second stage designed for consistent breathing performance in cold water, overhead environments, and demanding dive conditions. The MK19 EVO is engineered for reliability in challenging environments, while the A700 delivers smooth airflow with minimal breathing resistance across a wide range of depths.

The MK19 EVO first stage features a compact, environmentally sealed diaphragm design that isolates internal components from water and contaminants. Its rotating swivel turret and optimized port layout support streamlined hose routing and flexible configuration options. The A700 second stage is constructed entirely from metal, providing enhanced durability, efficient heat exchange, and stable breathing performance. An air-balanced valve system ensures reduced inhalation effort and consistent airflow delivery. The included R105 Octopus provides a dependable alternate air source using a simple downstream valve design with a high-visibility cover for quick identification.
