The SIG Kili2000 rangefinder is getting some great reviews from some that have used it. Some of what one long range shooter reported they ranged Semi trailers at 3000yards and cows at over 1800 yards.
from sig website is pretty impressive...
Extreme accuracy is what we were after when we engineered the KILO2000.
Updating at 4X per second in HyperScan mode, the KILO2000 rangefinder with patented LightWave™ DSP technology is amazingly fast as well. Couple that with the ability to range reflective targets at 3400 yards, trees at 1500 yards, and deer at 1200 yards for simple, intuitive long distance ranging. The built in inclinometer calculates AMR™ Angle Modified Range for angled shots. Our proprietary Lumatic OLED Display™, automatically adjusts display intensity to match ambient light conditions, bright in bright conditions and dim in twilight to protect your eye. The KILO2000’s simplified user interface displays your system status and while ranging, only provides your necessary data.
For a rangefinder that costs $500 those numbers are pretty impressive
