Coal Miner MetalDetector

I last used one when I was 12 and I''m 21 now. I grabbed the detector and started it up and took off outside, found nothing at first but annoying nails and wire from old fencing to my disappointment. I went down to the creek on my second day around where an old coal mine once was and started around an old pile of mining equipment.
