I have a rangefinder, but I most often use it to range landmarks as reference, to spot for another hunter I'm guiding, or to discover the distance to downed game after the shot. Ironically, I've ranged far more game animals I've passed on than shot. The most common use I have for it is when I'm shooting targets in the field behind my house. Since there are no landmarks between my table and my bullet stop at 100 yards, I have to use the rangefinder to set up a target stand if I want to shoot handguns at 10, 20, 30, or 50 yards.
