Rich Schmitt of Sanford, owner of Booty Savage, said he and his family went diving during the weekend with friend Dale Zeak and they discovered 64 feet of thin gold chain, five gold coins and a gold ring in the water, the Orlando (Fla.) Sentinel reported Tuesday.

"To be the first person to touch an artifact in 300 years, is indescribable," Brisben said . "They were there 150 years before the Civil War. It's truly remarkable to be able to bring that back." Booty Salvage is a subcontractor of Brisben's company. The Schmitt family said the gold haul is the largest in their salvaging years. "The greatest treasure is time with the family," said Lisa Schmitt, Rick Schmitt's wife.
