I just bought an ACE Garrett 250 and have been expeirmenting in my yard and it has so much underground trash I get beeps anywhere I aim. I havent found nothing YET but next door is a closed down bar/brothel that closed in the early 70`s and same thing happens when I detect there also. I take it off all metal and switch to coins and same thing happens but not as bad. I think I need to go hunting with an experianced hunter and get some tips on how to.I live in Missouri
