I know that you can get those water-proof bags, that looks very similar to a plastic food seals but designed to be dropped in water. Please be aware that sand not only scratch but can enter the sockets, volume key gaps and other small parts and may damage the unit from the inside though the exposure of salt and moisture. I highly recommend that you do not to take the DHD to the beach, I take my Ideos or Wildfire, just something cheap and wont break your heart if you do break it or damage it.
