The PN21K is an extremely versatile, compact, night vision monocular that is both functional and comfortable. This versatile device can be handheld, head mounted, mounted onto a firearm and even paired to form a binocular. Higher magnification 3x and 5x lenses are available as accessories to increase this device’s usefulness even further. The PN21K is auto-gated to prevent image intensifier damage if exposed to intense light. The unit features a very wide 36 degree field of view with its standard 1x objective lens. The monocular also has a built-in, infrared light source for situations where no ambient light is available. An indicator reminds the user when the infrared light is in operation.

The PN21K can be head mounted or mounted onto a helmet for comfortable hands free use that can also flip up easily when not in use. Pair it with a reflex sight or infrared laser and it can act as a sighting system when mounted on a firearm. Two units, fitted with 1x or 3x lenses, can be joined together to form a binocular. It features a removable objective lens, soft rubber eyecup and a removable light filter for bright light conditions. The PN21K is powered by a single 1.5 volt AA battery and incorporates a low battery indicator.
