The easy to hold ergonomic housing was especially designed for use underwater, while the housing is easy to hold and use even with one hand, the tough enclosure also features a unique closing system – a “Pressure Lock” thumb screw that exerts the optimal amount of pressure on the housings O-ring seal. The waterproof housing encases the small inner camera, and also stores a powerful drying agent called “Moisture Muncher” next to the camera that prevents internal fogging caused by heat and humidity trapped inside the housing.
