Only had a short time to hunt this morning. Went over to the soccer field at the school I work at. Alot of trash aluminum there. Anyway the 250 kept showing a signal of a one cent or dime, but when I dug some of them, they were mangled soft drink cans. I did find three Lincolns and the hood section of an old Matchbox car. Is this normal for the 250 to show this signal and be something else. Only time this has happened since I got it. I won't try it tomorrow, seeing it is Mothers Day and I don't think Joan would like for me to go out diggin' on her special day. Besides, I don't want to sleep down in the basement.
