Helmet Mounted Binocular Night Vision Goggles-The DA-PVS31 Advantage
The Helmet Night Vision Binoculars DA-PVS31 features an ergonomic and low-profile design. It offers better situational awareness than single tube goggles. Designed in direct collaboration with input from Special Forces operators, this binocular-type night vision goggle increases system resolution, greatly reduces head-borne weight, improves the system's center of gravity, provides additional operational utility, and enhances overall operator situational awareness compared to currently fielded dual-tube night vision binoculars.
