Tucson Dan: thanks, have you got the 5 by 9 coil for your ace 350? If you don't I'd suggest getting it and hit the play structures at the schools,playgrounds and parks. I've found 9 rings this yr just at elementary schools and play grounds. The structure play sights with the pebble rock is great with the ace and the 5 by 9 coil. You can recover way more items just hitting play structures for the day. The school I went to last night, I must have recovered over 200 targets in 4 hrs, so easy to just move the small pebble and retrieve your find and move on the the next. My finds have increased so much doing this. Give it a try, you will see your ring collection grow faster. And dig the foil, nickel and tab signals. You will dig a lot of aluminum and foil but When you do this a couple or few times a wk all those targets you recover, you will get those rings too that read junk, that all those kiddies drop. Cheers! Good luck.
