the archery shop i have been taking my bow to is wondering if the m pro cam has timing marks. he seems to think that my bow maybe out of time. no matter where i move my arrow notch or my arrow rest i continue to get fletching marks on the dropaway rest. i have turned my arrows every way turnable to try to clear and still nothing. i also am wondering if there is anyway i can send the bow to martin for them to check it and tell me if there is a problem with the bow. i have taken it to 2 bow shops and they are baffled. i dont want to spend no more money on arrow rest cause i had a bow doodle on it and that was worse than the dropaway.
