If you want a serious range finder you can look at the Sig Kilo 2400abs or the Terrapin. They are both very accurate.
For under $500 the Sig Kilo 2200 is accurate as well (+/- 1 yard). Just depends on if you want the Applied Ballistics calculator included with the range finder. For general usage, the Kilo 2200 can't be beat. Some use the Bushnell arc 1600 but it's more money than the Sig and not as good in my opinion.
