RE: ? for you bowtech pros
Use the bow square to set up your nock point in reference to the shelf. Put the rest on the bow. Then put an arrow on your nock point and lay it on the raised rest with a level on it. Then adjust your rest up or down to get a level arrow. Now just make sure that when the rest goes down, after the shot,it goes down far enough to be out of the way.
I always just set my nock point so that the arrow is even with the berger holes. I don't use a bow square. Doesn't seem to hurt doing it that way.
