RE: pro shop
Some pro shop owners get a little persnickety when they have someone present them with a problem that they bought somewhere else. I can' t say as I blame them too much. I would hope that, and have run into this myself, that he would want you for a future customer and do you right hoping you' d come back.
Yes, it is normal for you to have to pay shipping charges for returning your bow to the factory. Some shops, again " customer service" , will eat this charge themselves hoping to gain you as a customer, or taking care of a long time customer.
And yes, a basic tune can be performed. Setting center shot, cam timing (on two cam bows), and setting brace height are part of the basic tuning process that doesn' t have to have your arrows, etc.
This is a good example for everyone. Support your local pro shops before they are gone.
