Mastinson my brother also shoots a pse nova. And his has the same kind of markings yours does by what you have sead. He took his to the archary shop and they told him that it was just the film coating on the bow that had been scratched.The limb was not cracked! the bow shoots just fine and that was 3 yrs ago. but to be on the safe side maby you should take it to your archary shop you use and let them check it out just to be sure!
