I've received permission to detect on an 1890's home site. There is an old dam on the site that once held back about a one acre pond. I'm thinking it had to be the local swimming hole at one time. Kids being kids, they probably skinny dipped, had a rope swing, jumped in from the dam, etc. The whole area is now grown in. I'm thinking of going into what was once the pond with my 5x8 on the AT Pro and also doing the top of what is left of the dam. What would you do?
