This evening I hunted a lot next to mine.It had a house they burned down years ago.The yard was bone dry and a carpet of nails.There are power lines on 2 sides and a power box on the ground in one corner.I decreased my sensitivity and hunted with the chatter.I still found a nice 1944 Mercury dime at 5".I dug 2 wheaties and some copper lincoln pennies there last night.Every time I use this detector it amazes me.
