Dry times, for me my yeald of coins pr acre is low , mostly nuts and bolts and cut nails and a few slugs, I sure miss getting a silver coin , but i still move on in a relentless drone , the aluminum can was cut right in half by the disq and was about 10 ft apart then i hit the tab 5 ft away and it was 11" down whear as the other two bigger pices were on the suface and i got the tab to come thru in disq 11 " deep thats amazing so i know if another coin is lurking i will hit that found lots of Items 11" and 12" deep must be the depth of the plow , by the way the ct nails are for sale 10.00 each ha ha ,
