I got one of those iffy hits this morning that sounded like I should investigate. The first thing out of the hole was what I thought was a metal spacer. Just in case I checked the hole again with the PP and got a signal. The second ring (gold color) told me I had a ring spill and not a spacer. Both rings are very small and not worth anything but the spill factor is kinda cool. They were about 4-5 inch deep.
