Why would field tips shoot higher than broadheads?

Question:
When setting up my bow, I find my field tips shoot higher than my broadheads. Both are 100 grains. What causes this, and how can I correct this problem? I shoot a 28-inch carbon arrow.

Answer:
We are only guessing without having seen your setup, but we still feel that we can predict with 90% accuracy that you are experiencing fletching contact with your arrow rest. When fletching hits the rest it typically deflects the tail of the arrow slightly upward causing the tip to track below the tail. With a field point the arrow quickly stabilizes and flies true, however with a broadhead the blades of the head will first steer the arrow downward slightly before it stabilizes.

You have three options. First, you can take some time to completely tune your bow, which may include using a drop-away arrow rest if all else fails. Shoot through paper until your arrows are punching a neat hole with no tears other than for the fletchings. Second, you can simply live with it and sight your bow in for the impact point of the broadheads or third you can shoot mechanical broadheads that wind plane less than conventional heads and will shoot much like your field points.
