Did an early morning trip yesterday 6am to about noon. before the crowds and heat showed up. Tried to beat them beach comber raking machines. Not sure it’s better or not after/before them. They do seem to pick up bunch of trash but also i can see how they can also scoop up some good finds. Seen 2 styles of these.. one like a rake on a conveyer belt cant see that one picking up coins or much small solids, can easily catch a necklace,ring etc. but the other style skims the whole surface. Keeping everything above a screen and dropping sand.
