Firefield Nightfall 3.5x42 Night Vision Monocular FF18062 is designed for anyone who needs a reliable night vision device, whether you're a hunter, security professional, or just a nighttime animal enthusiast. These potent night vision devices use a powerful infrared illuminator, the PULSE IR system, to light up the night through the viewfinder of the monocular. Crisp picture quality is assured with the state of the art CCD chips in the Fire Field night vision unit, and you'll get excellent light transmission and resolution with the monocular's multi-coated optics. Since it's a monocular, the Fire Field Nightfall Monocular can only be used with one eye, maintaining your peripheral vision to stay aware of your surroundings. A rubber armored body and a lightweight frame make this Firefield monocular easy to carry with you into the woods. These night vision monoculars can even be mounted to a tripod using the integrated 1/4" tripod thread at the monocular's base. Fire Field has built the Night Fall with a 3.5x zoom, which comes in handy for extended nighttime observation. When night falls, you don't want to be caught without the Fire-Field Nightfall Digital Night Vision Monocular.
