I’m digging deep in a sand grass old park. It’s next to a sand filled bayou and when it overflows it leaves inches on sand over the entire park and the smooth it out but grass grows on top, but the sand goes deep. My problem is I have a found brass 1858 US military hat pin 1 1/2” long at a foot deep, but I’m also hitting aluminum can sometimes a foot and a half deep. They sound/vdi very similar is there something I can do to distinguish between the two? Any advice is appreciated.
