I have an ACE 250 as well and wanted to head out to some local areas today but something came up and I hit my back yard this morning instead. I have detected my back yard many times and decided to try something new. I turned up my sensitivity and dug up everything that beeped. I found 2 pennies, a sliding lock for a weight lifing bar, some foil, and a razor blade cutter 4 " down. It was fun to find new things in the back yard, expecially since the soil was wet from the rain. I am going to find someplace to search around tomorrow morning and hope I find something worth taking a picture of!
