We use our Miyay when we go camping, our campgrounds has miles of beach and the kids have a blast! It’s amazing how much change people lose when they go to the beach! I’ve taught them to bring everything they find back, it’s helps clean the beach too, buried pop cans and lids don’t belong in the sand. In this picture is just a bolt, but it’s over 100 years old, from a mining dock that was where the beach is, torn down 80 years ago, kinda neat! Thank you for a great product!
