Night Owl's classic military-style night vision goggle system is designed for hands-free use with a head-mask. Our hinged quick-release mount also allows the user to quickly flip the goggle up out of his field of view or to detach for use as a hand-held binocular. Designed for use while walking or operating a vehicle, the BG1 presents the user a non-magnified 1-to-1 image with a wide field of view. F 1.4 lenses improve depth perception beyond that provided by standard night vision viewers. And a light sensor automatically cuts power to prevent burning out the intensifier tubes in the event of exposure to a potentially damaging light source.
