I am new here and generally winging it when it comes to detecting. I was doing research on the Battle of Chancellorsville in 1863 and found an old map. I was able to overlay the map onto a modern one and identify a place that might be worth detecting. I went onto the county's interactive land map and found the surrounding property owners. My question is this, would you go knock on a few doors to get permission? I'm not shy and wouldn't trespass so I think it's the way to go. I only worry that the area has already been hunted and might be wasting time but I have new gear and time off so I want to do something proactive. What do you think?
