Precision Archery Tuning Tool

Easily cut my groupings by 25 percent by trueing my genesis bow. My sons paterned aready, but he would throw 1 out of 5 arrows. We think this has fixed it.

It is the best $20 I have ever spent. If you are having problems getting your bow tuned this is the tool for you.

Very helpfull

Have been doing the timing, a different way, this helps tremendously.
