Armasight BNVD 51 w/Helmet Kit Night Vision Binocular Black 1x Generation 3 64 lp/mm Resolution Features Helmet Mount With a built-in infrared illuminator, the Gen 3 Armasight BNVD night vision binocular allows you to navigate low-light areas and even read in complete darkness. Armasight night vision products are encased in a tough yet compact housing that is both fog and water-resistant. The BNVD Night Vision Binocular is designed to meet or exceed performance standards of military and law enforcement professionals, allowing you to maintain maximum situational awareness while navigating, observing and tracking moving objects and vehicles. The manual gain control lets you adjust the brightness level to your personal preference and if the ambient light level exceeds the limits of the BNVD, the automatic protective system will shut off the Image Intensifier Tubes (ITT) to prevent damage while observing under changing light conditions. Operates on a single AA battery or an optional remote battery pack. The BNVD articulates, allowing for it to be configured for use as a monocular over either eye, preserving your biological night vision in one eye if desired. The helmet mounting option allow you to use the BNVD as helmet-mount night vision goggles, adding the ability to quickly and easily move them out of the way in an instant, automatically turning off the BNVD when in the up position and restoring power when the unit is returned to the down position with no additional input from the user, extending battery life.
