Miss Archery,
Sorry to hear about your boyfriend/bow. A couple questions to see if we can solve the issue. First, how did he manage to dry fire the bow. It has a dry fire inhibitor. Second, is your bow a ProFusion. I am guessing yes because you mentioned the Quad scope.
Did you notice a change in the limb, or did you just dind the spot after the dry fire because you were looking. it could be something as simple as a wrinkle in the camo film. Better safe then sorry though. If you can get a good digital photo of it, I would like you to email it to me at TenPoint. Secondly, you can gently run a cotton ball or qtip over the spot and see if the limb grabs the cotton on a snag.
Let me know and I will do my best to help you.
Thanks,
Randy
