Why buy a metal detector? (Changes Weekly)
“To find buried treasure of course! (haha) I enjoy the hobby of finding stuff that you really don't know what it is and then having the chance that you might find something really worth a lot. But mostly the priceless time you spend with family and friends relic/treasure hunting!"
