I have an older Bushnell Yardage Pro I bought used for $100. It seems to be very accurate if the target is out in the open. If you are bouncing the laser off a flat paper target in an open field, it works flawlessly. If you are trying to range small game in heavy woods -- not so good. The difference between the higher end models and the low end models (like the Bushnell) appears to be in part the ability of the optics to reliably discriminate and range small, individual targets. One "fix" is to find a large tree or some other relatively large, reflective surface at the same distance as the range in of a small target. For example, instead of trying to range the squirrel, try to find the range of the tree trunk the squirrel is in. One other potential drawback of the Bushnell I own is that the range is displayed in black LCD digits, without a backlight. It is hard to read in low light, and useless after dark.
