NVM-321B Dual Tube Binocular Gen 3 PINNACLE®
The NVM-321B Dual Tube Generation PINNACLE® binocular features the latest rugged military design with specialized multicoated optics. The light weight NVM-321B features 3.2x magnification, automatic brightness control, a built in IR illuminator, and bright light protection. Its unique dual tube/dual eye configuration is the only night vision device that offers a true stereoscopic night vision image. The innovative wide exit pupil design eliminates the need for interpupillary adjustment and reduces the size and weight of the unit. The optional head-mount assembly and 1x Commercial lens convert the 321 from a binocular to a goggle, making the 321B the most versatile dual tube system available.
