Night Optics D-221 Gen 2+ Dual Tube Night Vision Binocular is a hand-held, versatile pair of night vision binoculars by Night Optics. Built with dual image tubes that operate independently, the redundant design of these night vision binoculars helps prevent malfunctions and keeps your binoculars working at their best level. These Night Optics night vision binoculars feature a 3.6x magnification rate with an extra-wide 80mm objective lens, capable of detecting targets over 900 feet away. The Night-Optic D221 Generation 2+ NV Binoculars use a patented design to create a universal interpupillary distance that needs no adjustment. What's more, Night Optics has built a close-range IR illuminator into the binoculars so you can illuminate even small spaces through your night vision device. Capable of running up to 30 hours on a single CR123 battery, these NightOps night vision devices will serve you well in any tactical or law enforcement situation, and, since they're weather resistant, in virtually any environment. These binoculars are available with your choice of High Performance, MS, or Standard Generation 2+ night vision systems.
