The Scubapro MK25 EVO DIN 300/S620Ti regulator system combines a high-performance first stage with a capable second stage for all-weather scuba diving. This pairing supports reliable breathing across varied underwater conditions, making it suitable for everyday diving and exploration. The MK25 EVO first stage features an air-balanced flow-through piston in a chrome-plated brass body, delivering smooth, consistent performance under pressure for scuba gear users.

Patented XTIS (Extended Thermal Insulating System) provides thermal protection, while anti-freeze features enhance reliability in cold-water diving. The system offers a practical port layout with two opposing high-pressure ports and four high-flow plus one axial super high-flow low-pressure ports to accommodate flexible hose routing for underwater gear configurations. The package includes the Scubapro R105 Octopus, delivering reliable breathing performance in a traditional downstream design with a dive/pre-dive VIVA switch and a reversible hose attachment.
