I'm new to the Etrac and have been hunting some local parks to get the feel for it. My probelm is that I have yet to dig anything deeper than 3 inches! Some of these parks are quite old and I know they have deeper coins in them. Todays clad count was $3.65 and it was all bassically on the surface. I am running in stock coin mode and have tried to use the "high" trash and "fast" recovery. I am sweeping real slow and am finding lots of coins but nothing old and nothing deep. I am "nulling" a ton and getting multiple tones and slowly work it untill I get a good tone in the small spot and then dig . Any help on settings that work for you in parks would be greatly appreciated. Thanks in advance.
