It was a lucky day for a South Florida treasure diving family this week after they found their rainbow's pot of gold ... or rather, the ocean's gold chains, to be exact. 

The trove, discovered off the coast of Fort Pierce, Fla., totaled nearly $500,000 and dated back to the year 1715. The treasure-diving family who found the booty were helped by a salvage diver named Dale Zeak, who chatted with Fox and Friends' Steve Doocy about the epic recovery.

"We have a boat that's specially equipped for treasure diving." he said, adding that they use engines to remove the sand over the wreck. Then, they go down into those uncovered holes to recover the treasure.

Listen as Zeak describes the excitement of the find ... and what happens next!
