I know they are not deep coils but where I go most finds will be current in the towel zone. Dropped within a couple of days. I know rings can drop in sand quick so unless you hit it in a day its going to be several inches deep in the soft sands of Myrtle Beach. Im sure I would want one for school and park fields. But what about beaches? These are DD coils aren't they? With preset GB on the Golden will the MD even work in the dry sand of the ocean beaches?
