Scrounger is right. That is a lot of nickels. Did you dig all of those in hopes of finding a gold ring? I would have expected more pull-tabs in the pic with all those nickels. Great job... If you keep digging those nickel beeps then gold will be found !!!
I usually wait until after the schools let out. Last thing I need is some overzealous teacher calling the cops on me. Even detecting with my wife I have had strange looks.
