ABSTRACT:
A method is provided for determining the straightness and balance of an archery arrow having a longitudinal axis and a magnetically attractive tip. The method comprises providing a magnet located in an elevated position, suspending the arrow by its tip from the magnet with the arrow's shaft passing through a stationary ring, spinning the suspended arrow about its longitudinal axis, and observing perturbations in movement of the spinning arrow relative to the ring that are indicative of warp or imbalance in the arrow. A device for performing the method of this invention is also provided. The device comprises a support frame having one end configured to be mounted to a wall or the like and another end bearing a magnet from which an arrow can be suspended. Preferably, the magnet is formed with a dimple for receiving and positioning the tip of an arrow for which straightness and balance are to be determined.
