Hello. I recenty got a bowtech destroyer and it came with one of the qad rests. It was set to low so when it is set off and drops, it smacks the bow. I want to raise it. What else do I need to do. Like nocking point etc. Let me know what I have to do. Thanks a lot.

Your arrow should line up with your berger hole (the threaded hole you bolt your rest to). If it does now, then I recommend not moving the rest at all, it will cause more tuning headaches than it is worth. Put some felt or moleskin on your shelf and leave it be. If you arrow lines up below the berger hole than go ahead and raise the rest up. You will also have to raise your knocking point. You can eyeball it pretty close without the proper tools, but if you really want to get it dead on you will need to bring it to a proshop. In my opinion, it is much more important for the rest to be at the correct height than to have it too high just so it clears the shelf.
