Got out with my Ace and Royal Sabre. The newer coins came from a relatively trash-free school-and most were found by the Ace. The Royal Sabre has a 4" coil and got the dirty work in the trashy park. Started out in notch mode UNTIL I found the ring by eyeballing it-too bad it wasn't real gold. Then I found one of the dirty dimes and an "iffy" signal next to it. I then switched to standard disc, rotated the notch control knob till the tabs gave a mixed tone and rescanned the hole. I found a QUARTER, DIME, AND PENNY next to the first dime. And the eyeballed ring now gave a high tone, indicating it was more like a square tab. Just a few targets I may have been without because of the notch.
