US Night Vision AN/PVS-31D Gen 3 Binocular - White Phosphor

Designed with an emphasis on special operations mission success, the AN/PVS-31D (F5032) night vision binocular delivers a tactical advantage in low-light and no-light combat scenarios. Engineered with close-focus technology, and an integrated IR illuminator. The AN/PVS-31D (F5032) provides improved operational performance and situational awareness.

Clear, close focus, superior performance tactical NVG - Users can maintain their cover while performing critical, up-close tasks—as near as nine inches—with more clarity than standard night vision goggles. An automatic vertical viewing system recognizes when the binocular is in use and prevents shut-off from activating when a user tilts their head to look up. An auto shut-off functions only when the goggles are in the stowed position.
