The Sig Sauer KILO3K rangefinder combines industry-leading Lightwave™ DSP technology with streamlined operation for hunters and shooters who demand fast, accurate range readings. This 6x22mm monocular delivers ranging capabilities up to 3000 yards on reflective targets with precision to the tenth yard or meter.

Featuring multiple range modes including Line-Of-Sight, Angle Modified Range, and Archery mode, the KILO3K adapts to diverse field conditions. The BDX™ 2.0 enabled system communicates ballistics data via Bluetooth to paired BDX riflescopes, displaying the exact illuminated holdover aiming point automatically.

Built-in environmental sensors measure temperature, pressure, and humidity in real-time for accurate ballistic calculations. The embedded Applied Ballistics Ultralight (BDX-U) software supports G1/G7 drag curves, while the Lumatic™ OLED display automatically adjusts brightness to ambient lighting conditions.
