Third Axis Calibrator (T.A.C.)

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.

Works as indicated.

It arrived quickly, but the “mirror” was incredibly scratched and hard to see through to actually look at your string in it. So then I was told about the protective film on it, removed that, and everything worked as it should. Please include a sticker on there for us dummies out there though.

Works great if you remove protective film first!

Make sure you remove protective film first :) Great idea though and it saved me $$ on a level for third axis verification.
