When you need every advantage to confidently take a shot, the black Sig Sauer 4x20 KILO850 Laser Rangefinder gives you a critical edge when it matters most. Its relatively low-magnification monocular provides a wide field of view to help find and track moving targets while bringing them in close to ensure you range to it. With a simple push of a button a 905nm invisible IR laser measures the distance out to as far as 1200 yards.
A dedicated processing engine provides a fast refresh rate for the laser, enabling four measurements per second so you'll have the most accurate range possible for moving targets or to confirm the range to a stationary subject. Complementing the rangefinder is an integrated inclinometer that measures the relative angle to the target. When the angle and range are combined, Sig's AMR ranging system adjusts the displayed range so you can compensate correctly for uphill or downhill shots and greatly improve your accuracy.
A simple two-button interface provides critical ease-of-use and a high-transmittance LCD display clearly shows the ranging information in your line-of-sight in an uncluttered layout. Designed for durability, the housing is made of a lightweight and durable polymer that is wrapped in slip-resistant protective black rubber armor. Weighing in at under 5 ounces, including the CR2 battery, the KILO850 will be a valuable addition to your kit.
