Depending upon your site, use as little discrimination as possible. When you get a signal, you may want to dig into the signal to see if it breaks up or is good. So when I say little discrimination, just below the iron tick mark. Sure you will dig some nails, but you WILL dig up other things that others missed because they discriminated to much. The signal will have a clean sound if it is good. ***NOTE***if you dig an iron nail or a handful of them, check the hole again if the signal is good. That means there is something else in hole besides the nails. Also- if you want to truly clean up, go to where the iron is with the small coil, scan it SLOWLY, then go back the same area with the larger coil. If you are searching an area of many acres you should plan on only searching an area the size of a living room. You will be amazed at how much is in such a small area in a "reported" hunted out area. Think of brand W users, who have to sweep their coils fast in an area. Sure they cleaned up and got most of the surface goodies, but now if you go slow, you WILL find good things. Keep it all in perspective. Further, the SOIL fluctuates based upon many factors, geo magnetic pull, low pressure systems, rain, climate, etc. You could go into one area today and find nada and go into the same area tomorrow and find a tremendous amount of stuff. It all depends on you and whether you are patient or not. Good luck and remember, don't cover a football field, only a small corner maybe 5 ft by 5 ft and go SLOW. Good luck!
