Like Neil says....read carefully. What you want to do is move your rest until broadheads and field points, have the same point of impact. Once they do, then you adjust your sight. When your field points and broadheads, don't have the same POI, and you just move your sight for the broadheads, your bow is not optimally tuned. Every time you want to shoot field points, you have to play around with your sight. You'll be changing back and forth.
