This is my fun, new way of hunting with the Compadre in oft hunted sites. I mean, when you think about it, anything that's been dropped at these sites is only gonna be shallow.So I set the disc right at the end of "iron" so the little pieces of foil will break up with a faster paced sweep and the deeper targets will kinda skip and just dig the "snap"signals. All you have to do is pass a coin quickly under the coil and you'll know what a "snap" is. The discrimination is so pure on the Compadre as compared to say the Silver umax that you won't miss many items-even a small valuable target gives a quick snap. I tested it out first on another site and checked all signals and , at least there, I was familiar enough with the Compadre I was right every time. Of course, I still dug tabs, large trash.
