Experience the Future of Precision: Thermal Imaging Meets Integrated Rangefinding
The Viper Gen2 650 LRF is Nitehog's most advanced thermal clip-on - the first in the Viper family to combine a high-sensitivity thermal sensor with an integrated laser rangefinder and a proprietary real-time ballistic computer. Built for hunters who demand certainty at distance, it delivers instant range data, automatic holdover calculation, and true zero-shift-free precision in one ultra-compact, field-ready device.
Key Highlights:
INTEGRATED LASER RANGEFINDER
Precise distance measurement up to 1,200 m, built directly into the device.
PROPRIETARY BALLISTIC COMPUTER
Real-time holdover calculation, field-verified beyond 400 m.
TRUE ZEROING — NO RE-ZEROING NEEDED
3 independent alignment profiles stored on-device.
AI SCENE MODES & TARGET LOCK
Smart scene recognition plus target lock with compass overlay.
RECOIL-ACTIVATED VIDEO RECORDING
Automatically captures the shot, every time.
ULTRA-COMPACT & LIGHTWEIGHT
Magnesium-alloy housing at ≤385 g without battery.
5-HOUR BATTERY LIFE
Single 18650 battery, full day of field use.
MEDIA CAPABILITIES
Photos, video, and live streaming via the NITEVISION app.
GUARANTEED PRECISION, EVERY SHOT
The Viper Gen2 650 LRF pairs an integrated Class 1M laser rangefinder with a proprietary, hunter-validated ballistic computer, giving you real-time holdover calculation verified in the field beyond 400 meters. Combined with true zeroing across 3 independent profiles, you get consistent, repeatable precision without ever needing to re-zero between setups.
CRYSTAL-CLEAR IMAGE, EVEN AT RANGE
Built around a 640×512, 12 µm VOx sensor and a 50mm F1.2 lens, the Viper Gen2 650 LRF delivers a 60 Hz frame rate for smooth, delay-free observation. With a detection range of 2,100 m and 1×/2×/3×/4× magnification, it offers exceptional clarity whether you’re identifying game at close range or ranging a target at distance.
HUNTING
The Viper Gen2 650 LRF's integrated rangefinder and ballistic computer give hunters the confidence to take ethical, precise shots at any distance, in any light.
PEST CONTROL
Fast target acquisition, AI scene recognition, and true zeroing make it a reliable tool for professional and recreational pest control alike.
SPORT SHOOTING & LAW ENFORCEMENT
High-recoil endurance and recoil-activated recording support repeatable performance in demanding, high-volume shooting scenarios.
COMPATIBLE WITH ALL-DAY OPTICS
Designed as a clip-on, the Viper Gen2 650 LRF pairs seamlessly with your existing daytime riflescope — no need to replace your current setup.
