Night Optics 10x Long Range Night Vision Biocular is a powerful night vision system that is perfectly suited for comfortable, long-term observation from an incredibly long distance away. Generation III night vision technology on these bioculars results in crystal clear images with little to no halo effect. And with a 10x magnification rate, these Night Optics night vision devices are capable of target detection up to 3000 yards away. All glass, military grade optics on the NightOps 10x Observation Night Vision Biocular couple with an integrated IR illuminator to deliver unparalleled night vision, even on moonless evenings or inside. Despite their high technology, these Night Optics binoculars don't have a steep learning curve; user-friendly controls and a fully-automated image tube give you a crystal clear night vision image with very little tweaking from the user. Available with gated or non-gated power supplies, the night vision monocular has little to no "blossoming" and reduces vision-hampering halos. Night Optics has constructed the biocular with a rugged and waterproof casing, so you can observe subjects virtually anywhere without worrying about the state of your monocular. Lightweight, rugged, and built for long-range night vision, the NightOps Gen III Long-Range 10x NV Biocular w/ IR Illuminator is a reliable option for all your nighttime observation needs.
