Sometimes while bottle diving you find something that you have no clue as to what it is, at least at first. In one of my final dives this year (I'm landlocked while I recover from neck surgery at present) I found a rather heavy item. It weighs five pounds and is approximately 10 inches long. Although it is rusty I believe that is due to contact with something on the sea floor. It is actually made of lead. It has the number "5" stamped on it. While paging through a treasure hunting forum I finally determined what it probably is. It appears to be a sounding lead used to determine water depth before electronics made that determination easier. Alan
