Description
The SCUBAPRO MK25 EVO / S600 Regulator System brings together two of SCUBAPRO’s most trusted components to deliver outstanding breathing performance, reliability, and comfort. Pairing the high-flow MK25 EVO first stage with the proven S600 second stage, this system ensures effortless airflow and consistent performance in all diving environments.
The MK25 EVO first stage is engineered for maximum airflow and cold-water resistance. Its air-balanced flow-through piston design provides constant airflow regardless of depth, tank pressure, or breathing rate. SCUBAPRO’s patented XTIS (Extended Thermal Insulating System) improves cold-water resistance by 30% and helps delay ice formation while maintaining smooth breathing performance in extreme conditions.
The S600 second stage is known for its durability and precise breathing control. Its air-balanced valve reduces inhalation effort at varying depths, while the metal valve housing ensures long-term reliability. Adjustable controls allow divers to fine-tune breathing resistance and airflow for optimal comfort underwater.
