Beach Treasures

I can't help but want to go dig in the parks and the sand when I see metal detectors. I'm thinking bounty hunter metal detectors would be a good present. :)  They have some commercials on tv advertising them and they do make me want to try them. I'd be excited to walk up and down the beach, or through the field at the park and find some random stuff. I'd like it even if it wasn't valuable, because I just like finding stuff!  I don't really know if you do as well as they make it seem on tv or you hear in stories but who wouldn't have fun with the suspense of wondering what is setting the detector off?
