Went to an old abandoned farm house today,have a Quatro with the 101/2 inch coil. Used the cross saving Relic-CJ mode and the coin Jewelry modes, also Hi trash density and Low trash dens. Ground is loaded with ferrris trash. Place is used for paint ball shooting. Would get a signal, nothing there. Had one signal in the dirt in my hand, but there was nothing there. Have only had this detector a very short while. Any help or suggestions would be really appreciated. Thanks
