For some ungodly reason when you tighten the locking screw underneath down to secure the windage it can knock the windage off very slightly
I wonder if this is a problem because of components used in the making of the product or perhaps a tolerance issue or both? I also wonder if Archery Innovations 'Bow Anchor Sight' share that same "tightening issues" (It costs almost twice as much).
At any rate, I will have to get one of these and play with it. Could be just what the doctor ordered for my old eyes. [8D]
