Got a deep high tone and dug approx. 6 inches and laid my steel digger approx. 18 inches from the hole on top of ground to further locate the exact position with my coil.
The signal was gone so I felt it was a ghost signal picked up my digger and went over hole again and high tone was back...so an object doesn't have to be next to the coin to be masked and if a horsehoe or can is in the ground 18 inches away you are not going to hear target in many cases. Yep it turned out to be a deep Barber dime..Sort of a test of masking under natural conditions...not man made conditions for testing...
