OK I get that the ferrous number is how high the iron content is ,and that the higher the conductive number is the better the target ( if we are talking coins and jewelry),but what about when both numbers are high or the same ? And when pinpointing is it the highest tone or the loudest tone in the absence of a high tone ? I have been finding some coins but nothing good yet ,although I am amazed by the number of signals I get in a spot I just scanned. I'm looking forward to all the great finds I'm going to make once it all falls into place.
