The Scubapro Mk25 Evo D420 with R105 Regulator Set truly epitomizes the convergence of tradition and innovation. This outstanding regulator set merges the iconic design ethos of the original D-Series regulators with cutting-edge advancements in breathing performance technology.

The Scubapro D420 regulator, the heart of this system, boasts a balanced valve housed within a full metal structure. This Progressive Flow Control Valve guarantees ample and consistent airflow, ensuring an unparalleled breathing experience that is as effortless as breathing on land. The unique fibreglass-reinforced nylon casing not only adds durability but also flexibility, allowing divers to connect the LP hose on either side.

A distinct feature of the Scubapro D420 is its dive/pre-dive system, which includes a switch with a thumb tab for adjusting the direction of airflow directly from the valve. The highly efficient purge button is a product of innovative design, giving the D420 its unique appearance. When paired with the illustrious MK25 EVO balanced piston first stage, the result is a superior regulator system designed with the needs and preferences of today’s divers and SCUBAPRO loyalists at its core.

The Scubapro R105 Octopus, an integral part of this set, offers dependable breathing performance in all marine conditions. The R105 Octopus, the D420 regulator, and the MK25 EVO first stage together form a regulator set that is truly a class apart in the realm of scuba diving equipment.
