RIX Tactical Night Vision Binoculars RNV-31S

The RNV-31S is a self-contained binocular night vision system designed to deliver exceptional clarity using only natural light sources such as moonlight, starlight, or sky glow. Each of the two objective lenses gathers ambient light and, through the built-in image intensifiers, converts it into a clear, visible image for viewing through the eyepieces.

When no ambient light is available, simply switch to the integrated infrared (IR) LED mode. This invisible light source, undetectable to the human eye but visible to the RNV-31S, illuminates the scene to reveal hidden details in complete darkness.
With robust construction, easy power management, and multiple protective safeguards, the RNV-31S is an excellent choice for law-enforcement, security, and outdoor night observation.
