If you do not want to get gap dependent, you can make a small mark on your riser with a water based pin and use that for a refernce point. I had to do that with a kid one time, just so he could get and idea on where to hold the bow. After a while, the mark wore off, or he wipped it off. But it worked great just to give him an idea. I only did that, because he could not quite get the gap method down. He is now a great instinctive shooter. Much better than I. [&o]
