This is the way I was showed to check if your target is big iron with explorer xs and I'm sure with others.You get a good tone , move coil away from target and turn on pinpoint and move it over target again if your target has moved from the spot you thought it was it is big iron the good sound was the halo effect .This is I'm sure old hat to old hunters but new hunters may find it useful.
