3E B31U Gen 3 Green Phosphor Binocular Night Vision Device
Tactical dual-tube binocular with NoctuVision Gen 3 tubes and external power support
The 3E B31U is a next-generation night vision binocular from 3E Tactical (Turkey), designed to improve night-time performance, terrain navigation and overall situational awareness.
The device combines compactness, low weight, dual-tube optics and modern functionality including automatic protection and integrated IR illumination.
The binocular configuration provides natural depth perception and spatial awareness, while the monocular option allows rapid adaptation to changing lighting and reduces eye fatigue.
We are a team of veterans who have seen this technology work in real missions. When we say the B31U is a reliable tool for field work — we say it from experience.
