Sig Sauer KILO8K 7x25mm 8,000 Yard Laser Rangefinder

The Sig Sauer KILO8K 7x25mm laser rangefinder pushes the envelope for long-range hunters and precision shooters who need ballistic intelligence in the field. With a maximum reflective range of 8,000 yards, this rangefinding monocular goes beyond simple distance—it pairs real-time environmental data with Applied Ballistics Elite (BDX 2.0) to calculate wind hold, elevation holdover, energy on target, and velocity at distance. Whether you're glassing for elk across a canyon or dialing in for a distant steel target, the KILO8K handles the math so you can focus on the shot.

The Gen II LightWave DSP engine includes new targeting modes—Extended Range (XR) for reaching out past conventional limits and Fog mode for low-visibility conditions—plus First, Best, and Last target selection to cut through clutter. An onboard digital compass and environmental sensors feed real-time data into the ballistic engine, eliminating guesswork on how conditions affect your shot. The active matrix OLED display is crisp and readable in daylight, showing all relevant ballistic data at a glance, and the Sig Sauer BDX App lets you configure the rangefinder and manage custom bullet profiles (up to 25) from your phone.

Connectivity is where the KILO8K shines: Bluetooth 5.x pairs it with BDX-enabled riflescopes and external devices like Kestrel weather meters and Garmin GPS units for a truly integrated shooting solution. Drop remote waypoints on ranged targets using BaseMap, and sync everything seamlessly. In the box you get a Multicam MOLLE bag, carry pouch, lanyard, tripod adapter, and a WeatherFlow Bluetooth WindMETER—everything you need to hit the ground running on your next hunt or range session.

Frequently Asked Questions

What's included in the box?

The KILO8K ships with a Multicam MOLLE bag for storage and transport, a Multicam carry pouch for quick access, a lanyard, a tripod adapter for hands-free setup, and a WeatherFlow Bluetooth WindMETER to feed real-time wind data into your ballistic calculations.

Can I use the KILO8K with my BDX-enabled riflescope?

Yes. The KILO8K features Bluetooth 5.x connectivity and is BDX 2.0 enabled, allowing it to pair with BDX-enabled riflescopes for a fully integrated ballistic solution. You can also connect to external devices like Kestrel and Garmin units via BDX External (BDX-X) for expanded data integration.

How does the KILO8K calculate ballistic solutions in the field?

The Gen II LightWave DSP engine combines range data with onboard environmental sensors (including a digital compass) and Applied Ballistics Elite software to calculate wind hold, elevation holdover, energy on target, and velocity at distance. You can load up to 25 custom bullet profiles and configure everything via the Sig Sauer BDX App.

What's the difference between Extended Range mode and standard ranging?

Extended Range (XR) mode is a targeting mode designed to help the rangefinder reach out to longer distances where conventional ranging might fall short. The KILO8K also includes Fog mode for low-visibility conditions and First, Best, and Last target modes to handle various hunting and shooting scenarios.
