I started out with two economy detectors which still work today. I would suggest printing a coupon for Hobby Lobby and buying one of the detectors there for under a hundred dollars. I have made used purchases from members of the forum and was very pleased with all them. Be sure to check the classifieds and sponsors here on the forum too. Oh, that nail finder is a lot of fun and perfect for parking lot scans. Very light weight and has that lil red button so you can GB on the fly. Im guessing you have a Harbor Freight detector, it never lied to me like my more expensive one does lol.
