TDI SL Getting A Nickel Thru Large Iron Wire

was amazed at how the TDI could get this nickle thru this iron wire

Looks like the nickel is offsetting the signal enough that iron isn't masking it. Can do similar thing with my analog vlf where you can hear a dime next to iron that is disc out. Very hard to do that if even possible when the signals are digitally filtered.

found a masked musket ball , with the TDI and the folowing setting GB-3.5- pulse delay17 US  conductivity switch in low  gaine of 6 I got this setting off this forum and it works i had just gone over the very spot several times from several derection this past week with the Equinox and the small coil  but it took the TDI to find this . up came the cut nails 1st and then still getting a high tone  up comes the musket ball
