This system should work on all concentric coils, (not the DD design) First thing is to put a marker in the center of the forward inner toe. The true center can be made by tracing the coil on a piece of paper, cutting it out, folding it in half then placing it on top of the coil. I put on a happy face as my marker, and drew a straight line on the outer forward toe, just to help with positioning and centering. This setup works best shallow targets. For deeper targets, use this link supplied by Garrett.
