Hello fellow detectors. I'm new to hobby and I agree that it's ridiculous that we need permission/permit to metal detect. I was able to obtain a permit for Baltimore County, at least it was free. I was basically told that I must stay away from historical sites, nature centers and athletic fields. I guess everywhere else is fair game. I reside in Harford County, but did not have similar luck. I'll probably stick to shallow streams and creeks. There's quite a few spots near me. I'll post any findings. Happy hunting everyone!
