I don't use a rangefinder. All my hunting is done on the ground, so I don't have to worry about how differenteverything looks from a treestand. With many, many years of practice behind me,I'm very good at judging distances within 30 yards.And I never take a hunting shot beyond 30 yards.

But I highly recommend using a rangefinder to anyone who can't (or won't) dedicate themselves to learning how to judge yardage and practicing it whenever they have the opportunity.
