RE: low and to the left
Mike, before you take your bow to the shop try moving your nock set. Loosen the set that you can turn it on the serving. Move it down a turn at a time until impact with your broadheads is even with your field tips. Don't be too concerned about sight adjustment at this time. Just move the set until impact is the same. This should correct both the low and left impact. You will need to readjust your sights when both tips impact the same.
