Has anyone ever set their etrac for silver only? I just hunted a park that was started in 1918, there were 5 of us, we hunted for 6 hours and no one got any silver, lots of wheats and nickels. Very little trash, hardly any clad. Of course clad comes pretty close to silver readings. The average depth of wheats were 1 to 5 inches, and the nickels were the same, as a matter of fact, I got a very worn "slider" of an indian nickel that was only 1/2 inch deep. I was using Bill_S trashy park pattern, then I tried TTF for a while. For theheck of it, I was watching a squirrel burying his nuts at the base of a tree that had to be over 100 years old, so after he left I went over there to see if I could find his nut, and for the heck of it I scanned the area he was digging and 2 inches below his exact spot I got a signal. I dug 2 inches deeper than he did and got a 1940 penny. I think I just figured it all out, the squirrels are stealing the silver and replacing them with wheats, that is why the wheats were so shallow, does that sound like a good hypothesis? Now to figure out where those dang squirrels are depositing the silver........nge
