The PS-31 BNVD has independently pivoting tube housings that allow the operator to run the goggle in a binocular or monocular configuration. Using two tubes at once allows the eyes to create depth perception and increases the ease in maneuvering terrain and obstacles as well as operating devices such as control panels and door knobs. Monocular configurations allow for ease in transitioning between various lighting conditions that often occur on the battlefield and cause operators to switch between night vision and weapon-mounted optics. Another benefit to the pivoting tube housings is the ability to mount the flatten goggle against the front helmet surface when stowed. Includes lens tissue manual soft carry case helmet mount and one CR123 battery.
