torture test in cinders & nails

[nagant]

replaced some sidewalk and removed about 6 inches or crud to put crushed limestone in, pile about a eight foot circle 2 foot high.. Cinders, iron scrap, old nails plus EMI what a detecting mess. I manually G\D'd at 86 then did auto and it was 82. Only found two wheaties, '52 & '17 in park1 and sensitivity 22. Then just tried about everything i could think of. Emi was to much for 5khz unless sens was under 14. beach ran quiet but it too needed lower sensitivity. field 1&2 seemed unusable in this stuff. Going to spread the pile out and hit it in the morning, doubt anything got missed but fun to try.

Try Field 2 and bump up the iron bias to 3 or 4.

Will give it a try, thanks. It's a small pile but old dirt. Just tried that and worked nice but no coins, just aint any left.
