I test drove my Sig K2000 laser range finder today for the first time and was very impressed. It easily ranged our cows/horse at 847yds, oil tank batteries at 1,567yds, and with its fast four-times a second scan mode I was able to range a soaring buzzard at 454yds. The cows were black, white, and the horse is a bay color. The instructions state it will range past 2,000yds on reflective targets, 1,500 on trees, and 1,200 on deer The three objections I have with it are the aiming circle is too large, the glass could be better, and there is no attachment for a tripod. Long Rifles Inc makes an attachment for it so you can attach a tripod though. All in all I believe it's an excellent range finder for +/-$400. I'll give it a good test in October when we're after antelope in Colorado. If you're looking for a good range finder check out the Sig.
