MK25 EVO / A700 Dive Regulator System

Product Description

The SCUBAPRO MK25 EVO/A700 regulator system delivers uncompromising breathing performance in all diving conditions. Designed for divers who demand absolute reliability, this system guarantees smooth, low-effort airflow whether diving deep, breathing hard, or operating in extreme cold water.

The MK25 EVO first stage features an air-balanced piston design that provides ultra-fast breathing response, instant air delivery on demand, and exceptionally high airflow, regardless of depth, tank pressure, or water temperature. Its patented XTIS (Extended Thermal Insulating System) enhances cold-water resistance and delays ice formation without affecting breathing performance.

Paired with the MK25 EVO, the A700 second stage stands out with its rugged all-metal construction, including a metal valve housing and screw-down cover. This design allows for a larger diaphragm in a compact housing, increasing breathing sensitivity and ensuring durability even during years of aggressive diving.

Together, the MK25 EVO and A700 form a premium regulator system that excels in tropical waters, cold lakes, and extreme polar environments alike.
