Luna Optics Quantum Digital 6-36x50 Day/Night Vision Binocular with Integrated 1635 yds Laser Rangefinder

The QD-B50-PRO extends the laser rangefinder to 1,635 yards—the longest integrated LRF in the Quantum Digital lineup—while keeping the same 654-yard night vision, dual AMOLED eyepieces, and electronic image stabilization that define the platform. If the standard QD-B50's 1,100-yard ranging isn't enough for your shooting distances or survey requirements, the PRO closes the gap.

Built on Luna's Quantum Digital sensor (0.0015 lux), 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 detection to the sensor's full 654-yard range in total darkness, and when you identify a target, one button press returns distance to the meter out to 1,500 meters. A built-in recorder captures QHD video with audio and 16.1-megapixel stills for documentation.

Key Features

• 1,635-Yard Laser Rangefinder — Integrated Class-3R LRF returns distance out to 1,500 meters, the longest range in the Quantum Digital binocular series
• 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

• Long-range shooters and hunters who need precise distance data beyond 1,100 yards and positive night target ID 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 the longest integrated LRF available
