To see how various artifacts at different depths are seen by each detector
'Spoon' Odd shaped target at depth-13'' Roman Fibula 7'' deep -low conductivity
Very high conductive buckle, loved by detectors Thimble can sometimes be a difficult target 12'' deep
Large musket ball can give a strange signal 10'' Deep Lead weight can confuse some detectors 14'' Deep
