The Dixon Broad Head aligner is/was a great tool it is no longer made. 😥
The magnet has a alignment hole in its center.The point of the broad head is placed in the hole and when the shaft is rotated the magnet would show movement when the broad head is out of alignment.
I sold out last year .Those that own one have a nice tool. That only advantage over others is misalignment is magnified
