I agree, range finders are a top tool to have and use
on all my ladderstand sets and even many places I hunt yr after yr, I mark trees, or even place markers out to show yardages, in about 5 or 6 directions all around my sets, there all color coded too
it sure makes life a lot easier when deer show up fast, and don't have to try to range em , or guess
lots of time is hard to have a range finder in hand when action happens fast, and why I!* like pre marking yardages
and too bad on the miss, but still better than wounding and loosing a deer
