Last time treasure-hunter Beau Ouimette was featured on RightThisMinute, he had found a stash of GoPros and cell phones. But this time, his booty is a little older. While snorkeling, Beau uncovered a cannon ball and a musket that he believes to be from the Civil War era. It's not confirmed that the 19th century is when his find is from, but even if it isn't, it's still an awesome find.
