The V3 LRF 35-640 is the top of the Rattler line - the same integrated laser rangefinder and ballistic calculator as the 35-384, now paired with a 640x512 sensor that delivers a fundamentally sharper thermal image. A 35mm Germanium lens, sub-15 mK thermal sensor, and a 2560x2560 OLED display combine to produce the best 640-resolution thermal image in the Rattler family, with detection range pushing to nearly 1.5 miles on a six-foot target. Base magnification starts at 2.5x and scales to 20x through a newly designed eyepiece that makes this an ideal option for predator hunters working wide-open terrain at distance. The fully integrated 1,000-meter laser rangefinder lives inside the lens - no external device, no added bulk - and feeds directly into an on-board ballistic calculator for a firing solution without breaking your setup. A shutterless NUC system and Image Boost 2.0 keep the image clean and stable at every magnification level. Large, sturdy buttons handle gloved operation in cold-weather conditions, and the removable rechargeable NE-4400 battery delivers over 5.5 hours of runtime with straightforward field installation. On-board recording captures 1280x1280 video and audio to 64GB of built-in storage, and Shot-Activated Recording handles the footage automatically. Built-in WiFi lets you live-stream or offload to another device. The firmware package covers the full range of customization: 10 reticle types in 4 colors, multiple color palettes, 10 brightness and contrast settings, picture-in-picture, multiple zeroing profiles, ballistic calculation, multiple laser rangefinding modes, hotspot tracking, defective pixel repair, and an on-board pitch scale. An American-made ADM mount is included. 640x512 resolution with 12-micron sensor for the sharpest thermal image in the Rattler lineup Sub-15 mK thermal sensitivity for superior image clarity in any conditions 2560x2560 OLED display for an ultra-high-resolution sight picture Shutterless NUC and I
