MK2 Evo/S270 Dive Regulator System
Recreational divers looking for solid performance in a regulator system and ready to step up from their entry-level systems are going to love the MK2 EVO/S270. The S270 second stage features an air-balanced design whose compact casing and internal aerodynamics produce extremely low work of breathing. Teamed with SCUBAPRO’s classic MK2 EVO, the only downstream piston-style first stage with internal components specifically designed to resist freezing in extreme cold-water conditions, this regulator combo is affordable and durable while delivering smooth and reliable breathing performance.

- Lightweight S270 casing, made of a fiberglass-reinforced nylon core and a special PU outer layer, is extremely durable plus helps reduce jaw fatigue and improves diving comfort
-
Technopolymer plastic barrel with a metal thread and a balanced valve helps save weight and provides a surface that ice crystals can't grab onto when diving in extreme cold water.
-
Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
-
Dive/predive switch is easy to use even wearing thick gloves.
-
Compact and efficient exhaust tee minimizes exhalation effort
-
Classic downstream first stage piston design features a chrome-plated brass body with one high pressure and four low pressure ports
-
Patented XTIS (Extended Thermal Insulating system) insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in extreme cold-water conditions without compromising breathing performance.
-
Chrome-plated marine-grade brass body houses an oversized piston that provides better breathing performance by increasing airflow
