Thanks for the info!! I need to find a DEEP, old silver dime, with no iron in the hole, to make sure I am doing this correct!! ( only deep dimes HAD rusted iron also, and single silver dime was pretty shallow, less than 6 inches. )
If you go in all metal mode (quick mask) You can swipe back and forth over the target and if FE stays above 20 you know you are experiencing halo from rust. If it bounces down to 10 or twelve more often than just on occasion, it's probably a good signal.
