The PS-31 Binocular Night Vision Device (BNVD) is a compact, lightweight dual-tube goggle designed to deliver superior night vision performance. Replacing the legacy PS-15, the PS-31 features high-performance U.S.-made Gen 3 image intensifier tubes that offer enhanced resolution and a wide 50-degree field of view. Its innovative design reduces weight and improves balance for greater comfort and situational awareness.

With independently pivoting tube housings, the PS-31 allows seamless switching between binocular mode—providing depth perception and better terrain navigation—and monocular mode for easier adaptation to changing lighting conditions. The ability to fold the tubes flat against the helmet ensures a low profile for increased safety and durability. Built with operator feedback, the PS-31 is engineered for maximum visibility, comfort, and versatility in demanding environments.
