When you first purchase a 10 yard Arrow Sight box, you will need to determine the range that you would like to use it at. This can be done by finding the distance between two points and then converting that into yards.
There are a few factors that can effect how accurate your arrow shot will be:
-Your bow's draw weight (thinner bows will require less effort to hit targets at long distances while heavier bows will required more effort)
-The height of your bow's arch (taller bows shoot higher arrows which compensate for increased wind resistance)
