The first of its kind, the Revolution Arrow Tuner allows you to square your insert and arrow, tune broadheads, and confirm arrow shaft straightness. Broadhead tuning is achieved by supporting misalignment correction between your arrow, insert, and broadhead itself. You can perform this action after leveling the tuner, leveling the arrow, broadhead installation, and using the tools dial indicator (which reads .001) to check for broadhead misalignment. The dial can also be used to check the straightness of the arrow.
