Scubapro MK 25 EVO / S620TI w/ FREE R105 Octopus

The Scubapro MK25 EVO / S620Ti regulator system with R105 Octopus combines a high-performance balanced piston first stage and a lightweight titanium second stage for consistent breathing performance across a wide range of diving conditions. The air-balanced design maintains stable intermediate pressure regardless of depth or remaining tank pressure, supporting smooth inhalation and reliable airflow throughout the dive. This regulator configuration is commonly used by recreational and advanced divers seeking durability, streamlined hose routing, and dependable cold water operation.

The MK25 EVO first stage is constructed from chrome-plated marine brass and incorporates Scubapro’s Extended Thermal Insulating System (XTIS) to improve freeze resistance in low temperature environments. Its swivel turret and multiple port layout allow flexible hose positioning for clean setups. The S620Ti second stage features a titanium inlet tube, reinforced technopolymer housing, and an air-balanced valve to reduce breathing effort while minimizing jaw fatigue due to its lightweight design. The included R105 Octopus serves as a reliable alternate air source with a classic downstream valve and high-visibility front cover for easy identification in emergency situations.
