The ScubaPro MK25 EVO DIN 300/S600 Dive Regulator System combines an air-balanced first stage with a responsive second stage to deliver reliable, smooth breathing across depths and tank pressures. Built for consistency in demanding diving conditions, this regulator is designed for scuba and underwater exploration and pairs with essential diving gear. It includes a Scubapro R105 Octopus as part of the system.

The air-balanced flow-through piston resides in a chrome-plated brass body to maintain constant airflow, adapting to depth, tank pressure, or breathing rate. The patented XTIS (Extended Thermal Insulating System) thermally insulates the inner mechanism for improved cold-water resistance and delayed ice formation without compromising breathing performance. Anti-freeze protection further enhances reliability in extreme water temperatures.

Versatility and control are central to the design: two opposing high-pressure ports allow first-stage orientation up or down, while four high-flow and one axial high-flow low-pressure ports on a swivel turret maximize hose routing options for a clean scuba setup. An external intermediate pressure adjustment lets technicians fine-tune performance quickly and easily. The air-balanced second stage valve supports smooth inhalation across varying depths and supply pressures in underwater environments.

Durability is built into the construction with a rugged reinforced technopolymer case and front cover, stainless steel frame, and a metal valve housing designed for years of aggressive diving. User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch. A Super-flow hose with an oversized bore increases air delivery on each inhalation, and the orthodontic mouthpiece provides a comfortable, secure grip during long dives.
