I do a little detecting ever now and then.
A friend owns a dredging company and last summer they dredged up some ballast stones near a spot called the gold hole which is supposedly where a pirate(i forget which) buried his treasure in the mid 1700's, several treasure hunters have dug up to 40' deep produced nothing but mud and a lot of water
. Anyways they called me to come run the MD over the sludge they were depositing on a bank nearby. I was lucky enough to find a severely encrusted piece of old chain(looked like a chunk of pavement before I cleaned it up), and what we believe is a button off of a civil war officers uniform. Other than that I have found a bunch of small items including what we believe is a brass prop keyway, almost 3/4" thick and 5" long.
Its a fun hobby but I doubt I could make a living at it, I am in it more for the history
