Looking for treasure with metal detector

On any given day, one might spot Lancaster, Ohio, resident Mike Haer in an open area with a metal detector in hand, looking for his next small treasure. His rarest and most exciting find? A Civil War button he unearthed in the same spot where the soldiers conducted their training. Haer wants to help banish the stigma some people have of those who use metal detectors. "I want to educate them that we're not making money at this -- many of us do it for the thrill and are willing to donate our finds to museums," he said. • Article
