Video - Minelab EQuinox sweeping dime with foil and nail as maskers

I wonder, is there an actual single freqs ops detector that will yield as high as percentage of actual air test ID of this clad dime when sweeping this scenario using 11 " coil?

Enjoy.
This video speaks to the versality of the Multi IQ tech IMO.

It's something how the TID gets dragged down, I am going to have to go over some areas again, I wasn't digging 19's and 20's because I thought they were zincs.
