Description

The new S270 is available with a MK11 first stage for divers seeking an air-balanced diaphragm design delivering effortless airflow unaffected by depth, tank pressure, or breathing rate. The MK11’s chrome-plated marine-grade brass body has sealed internal parts to prevent water and pollutants from fouling the inner mechanism while enhancing cold water performance. The new air-balanced S270 provides smooth breathing performance in a bulletproof, anti-scratch design that’s able to handle years of hard use. It comes with a dive/predive switch, an effective purge, and a compact exhaust tee that minimizes exhalation effort.
