Recreational divers looking for solid performance in a regulator system are going to love the MK11 EVO/S270. The NEW balanced diaphragm MK11 EVO first stage is more compact than its MK11 predecessor, with a forged brass body, thermal fins and protective plastic bumpers to ward off scratches. It features an innovative double spring layout that contributes to overall compactness while improving reliability. The MK11 EVO’s two HP ports are set on a 15-degree angle for more comfortable hose routing, and the four LP ports are all high-flow. The S270 second stage features an air-balanced design whose compact casing and internal aerodynamics produce extremely low work of breathing. Delivering smooth breathing performance in a bulletproof anti-scratch design, the S270 comes with a dive/predive switch, an effective purge, and a compact exhaust tee that minimizes exhalation effort. CE certified for all diving conditions including cold water, this compact reg combination is a must-have addition to any dive bag.
