When you disc a field can coins turn flat so its easier to detect? Seems like everytime they disc the airbase here coins show up where i already metal detected.The disc only goes down about 6 inches so is it separating the coins from iron like nails and such? I do know that when coins are sideways my Garrett gives a strange signal.I cant dig everything because there is millions of nails out there.The funny thing is i have found coins under an iron signal after removing the iron.Has anyone else experienced this or is it my metal detector?
