I am looking for a good rangefinder under $1000. I have a Leica 800 now that I am not satisfied with. I use the range finder resting on a sandbag, so I know it is not me shaking. If the target (whitetail) is over 450 I have trouble getting any readings, sometimes 400 is about all I can get. I want something that will always read to 700 or so. It doesn't have to be a laser model, but I do not want one where the size of the animal influences the reading. Does anyone make a good one that uses focus to get a reading? Maybe the 1200 scan is what I need.
