These are from a USFS housing complex torn down recently, but built in the fifties. I have been over this ground with my Etrac, Tesoro Silver uMax and a Fisher CZ3D. I have found four or five Tootsie toy's,a nice cap gun, a few wheat's, and lots of clad here but NEVER any silver. I was always always disappointed in not finding some silver. Well my first hunt over the same ground yielded two silver dimes, two wheat's (not shown) a double edged razor that still works !!!! and the collar badge. I was BLOWN AWAY !!! One dime had a 1 inch large thick washer above it, the other was in the area covered by roofing nails from prior repairs. The badge was near a fire-ring with lots of trash that I'm sure masked it before. I am very happy with my 3030,, I run with long tones and they just blast my ears when on a good target, they really stand out over the blips and burps of trash and ground noise. Deep off, fast off for the most part, I see little difference in the long tone when you have fast on so I use it in heavy trash sometimes,,, but honestly try to keep it off (fast off) most of the time. This machine rocks,,,,,, thanks for looking,,,,
