How many of you take and use rangefinders while hunting? It obviously depends on the kind of hunting and hunting terrain you are involved in. For the Eastern whitetail hunter hunting in wooded areas where almost all shots are 150 yards or less, there's no need for a rangefinder. But what about the hunter in open-country terrain where long shots may be needed? I've never used a rangefinder while hunting even in wide-open country, so I'm wondering whether others find them useful.
