When I bought all my stuff he put a tru-peep on it. I could not make it work so I had a shurz a peep put on. I got charged for both of them. Now that made him about 4 dollars, but if I were him, I would not have charged for either. The guy does wonderful work. He tuned my bow for me and it is perfect. I am around a whole lot of hunters, thats about all I hang around, I wish that I could refer them there, and I might, I would just have to tell them how they are.
