"Introducing the smallest rangefinder in the world. At just 2.7""L x 1.9""W x 1.2""H, the SIG SAUER Kilo Micro Rangefinder is roughly the size of a bar of travel soap but it delivers everything you want in a ranging optic. GEN II Lightwave DSP ranging technology delivers faster, more accurate ranging for reflective targets out to 1,000 yards and deer out to 600 yards. Information is presented via the red/green TOLED display featuring Lumatic adaptive brightness for ideal visibility in any light. AMR technology compensates for uphill and downhill shots, and Archery Mode makes it just as useful for bowhunts as it is for rifle hunts. The Kilo Micro Rangefinder comes with a unique QDI quick-detach magnetic harness mount that keeps the unit secure and provides fast, secure attachment and removal. Other features include 4x magnification and 8 onboard firearm ballistic groups. The built-in rechargeable lithium-ion battery provides up to 3,000 ranges on a charge.
