Introducing one of the most sophisticated Rangefinders on the market, combining exceptional range with advanced features and incredible speed. At its core, the KILO5K is a classic Rangefinder with an incredible 5,000-yard range and an amazingly fast Gen II Lightwave DSP engine that returns 4 ranges per second on targets well over a mile away. It features onboard sensors that measure temperature, pressure and humidity for accurate real-time ballistic calculations, and shows all the info via a beautiful OLED Lumatic display. But that's only about half the story. The real heart and soul of the KILO5K is its ability to feed data directly to your BDX scope (sold separately). In BDX-U mode, the KILO5K utilizes your ballistic profile and measures environmental parameters in real-time to instantly calculate precise windage and elevation solutions in either MOA or MILs. This information is displayed in the Rangefinder-and is also communicated via Bluetooth to any paired BDX sight to provide the exact illuminated holdover aiming point. Pair it up with a compatible optic, and you have everything you need to take your best shot. From ranging, to targeting, to impact, SIG SAUER optics connect the dots.
