The MK11 is a great choice for dive-trekkers. The balanced diaphragm MK11, with its chrome-plated brass body specially designed to reduce size and weight, is an ideal travel companion. Its system features internal parts that are sealed from the elements. 

Features:

• ir-balanced diaphragm first stage design delivers constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.

• Marine grade brass body has sealed internal parts to prevent water and pollutants from fouling the inner mechanism while enhancing cold-water performance.

• Two high pressure, two low pressure and two high-flow LP ports maximize hose routing options.
