I was detecting a Corps of Engineers lake beach this evening, which I have done many times in past years. The park attendant came up to me and asked me to leave. He said it was illegal to detect the beach. There was one other person on the beach and I made certain I didn't detect in that area. Before I ever detected a Corps beach I did my research and found that there are restrictions in detecting Corps beaches, the only restriction that I remember that would apply to me was nothing larger that a hand scoop can be used. I have always complied with that and have never been confronted before. I used to have a printed copy of the regulations, but it was in my bag, got wet and since I had never needed to share it with anyone, I discarded it and never felt the need to replace it. My question is have the rules changed?
