Most rangefinders above $250 will provide an accurate range and allow for angle compensation so the archer knows their true range to the target. Most rangefinders are accurate to within +/- 1 yard to a certain distance; however, as the distance to the target increases, that +/- 1-yard readout may shift to +/- 3 yards or more. Archers need not fret. Get an accurate rangefinder to +/- 1 yard out to 100 yards, and you're ready.
