Sig Sauer Kilo3K 6x22 Rangefinding Monocular

The Sig Sauer Kilo3K: Precision Rangefinding Meets Modern Ballistics

The Kilo3K represents a significant advancement in rangefinding technology, combining Sig Sauer's proven optical engineering with integrated ballistic solutions. This is not merely a distance-measuring device—it is a complete ballistic calculator that fits in your hand.

Core Technology

At the heart of the Kilo3K lies the Lightwave DSP (Digital Signal Processing) engine, Sig Sauer's fastest ranging processor. This technology delivers exceptional speed and accuracy across distances up to 3,000 yards. The optical system features a 6x22mm configuration with SpectraCoat anti-reflection coatings, ensuring superior light transmission and clarity in demanding field conditions.

Integrated Environmental Sensors

Unlike conventional rangefinders, the Kilo3K includes onboard temperature, pressure, and humidity sensors. These measure real-time environmental conditions and feed that data directly into ballistic calculations. The result: windage and elevation solutions that account for actual atmospheric conditions, not theoretical assumptions.

Multiple Operating Modes

The Kilo3K offers five distinct range modes to match your shooting discipline:

• BDX-U (Applied Ballistics Ultralight): Embedded ballistic engine with support for G1 and G7 drag curves, accommodating up to 25 bullet profiles
• BDX-X (Applied Ballistics External): For advanced shooters using external ballistic software
• AMR (Angle Modified Range): Accounts for shooting angle, critical for hunting and field positions
• LOS (Line-of-Sight): Simple distance measurement
• Archery Mode: Optimized for bow hunters

Target acquisition modes include First, Best, Last, Fog, and Extended Range settings.

Bluetooth Integration and Display

The Kilo3K is BDX 2.0 enabled, meaning it pairs via Bluetooth with compatible Sig Sauer BDX riflescopes. Once paired, ballistic solutions transmit wirelessly to your scope, which displays an illuminated holdover dot—eliminating manual adjustments and calculation errors.

The red OLED display features Lumatic technology, which automatically adjusts brightness for daytime use or low-light conditions. Results display in yards or meters to tenth-unit resolution.

Practical Features

HyperScan provides four range updates per second in scan mode, allowing you to track moving targets or verify distance to multiple points downrange. RangeLock locks onto distant targets when precision matters most.

The compact polymer housing is lightweight and durable, with an integrated tripod mount for stable long-range observations. Runtime reaches 4,000 ranges per battery charge.

Smartphone Integration

The free Sig BDX App (iOS and Android) allows you to drop remote waypoints using BaseMap, creating a detailed map of your hunting or shooting area with precise distances to key landmarks.

A Tool for Serious Shooters

The Kilo3K is built for hunters, long-range shooters, and anyone who demands accuracy. It eliminates guesswork, accounts for real-world conditions, and integrates seamlessly with modern optics. This is rangefinding technology that respects your skill and your time in the field.
