Third Axis Calibrator (T.A.C.)

Works as described I haven’t shot my bow down hill to see if it’s on or not but this gadget is super handy if it doe why it’s supposed to..great quality in these arrow raps craftsmanship..

The third axis calibrator is well designed and probably would have worked well but when I received the item the mirror was scratched to the point I could not see the reflection of my bowstring to be useful. Good idea, but the mirror needs more protection to survive shipping and handling.

They were exactly as advertised.

It worked exactly as advertised; I had no issues with its quality. It worked great to sight in my third axis. 5 star
