Night hunts and property surveillance mean carrying a night vision device in one hand and a rangefinder in the other — switching between them, re-acquiring targets, losing critical seconds. The QD-B50 puts 654-yard night detection and a 1,100-yard laser rangefinder behind a single pair of stabilized eyepieces, so you ID, range, and record without ever breaking your field of view.

Built on Luna's Quantum Digital platform, the binocular transitions automatically between daylight color enhancement and IR mode with an internal filter — no manual cap changes. The 1-watt 850nm illuminator (Class-3R) pushes usable imagery to the sensor's full 654-yard detection range, and when you spot a target, one button press returns distance to the meter out to 1,000 meters. When you need a record, the built-in recorder captures QHD video and 16.1-megapixel stills with audio.

Key Features

• 1,100-Yard Laser Rangefinder — Integrated Class-3R LRF returns distance out to 1,000 meters, removing the need for a separate rangefinder
• 654-Yard Night Range — A 1-watt IR illuminator (850nm, Class-3R) reaches deeper into total darkness than 750mW units, giving you confident target ID at serious distance
• Quantum Digital Sensor (0.0015 lux) — 30% more sensitive than the G3 generation, with a proprietary Ultra Night Vision mode that pulls usable detail without IR active
• Electronic Image Stabilization — EIS at 6x optical magnification smooths handheld viewing and eliminates the shaky video that plagues unstabilized digital units
• Automatic Day/Night Filter — An internal color-enhancing filter switches automatically between daylight and IR modes — no manual cap removal, no missed moments
• 6–36x Digital Magnification — Fast f/1.0, all-glass, multicoated 50mm objectives maximize light gathering while 6x digital zoom extends your reach to 36x
• Six Color Modes — Daytime Color, Nighttime Color, Black & White, NV Green Phosphor, NV White Phosphor, and Amber
• Dual 1024x768 AMOLED Displays — Independent eyepiece displays with deep blacks and wide viewing angles, ruggedized for cold-weather operation
• QHD Recording with Audio — Capture 1440p video at 30fps or 1080p at 60fps with built-in microphone; 16.1MP stills for evidence-grade documentation
• Wi-Fi Streaming & HDMI Output — Stream live to your phone via the IRAPP companion app (iOS/Android) or connect to a monitor via micro-HDMI for team observation

Ideal For

• Night hunters who need two-eyed comfort, positive target ID, and instant range data without carrying a separate rangefinder
• Search and rescue teams running multi-hour operations with live streaming to a command post and precise distance measurements for coordination
• Property and security professionals who need recorded, time-stamped surveillance evidence with range-verified target distances
• Stargazers and wildlife observers who want a day/night crossover binocular with serious magnification, image stabilization, and built-in ranging
