Beyond Oak Island

When a young treasure hunter tells Rick and Marty he is hunting for the long lost treasure of pirate Jean Lafitte, the brothers are so intrigued they send Matty Blake to assist in a dangerous dive to further the search.

Oak Island metal detection expert, Gary Drayton joins a relative of Butch Cassidy on a treasure hunt to the legendary robber's roost and unearths a piece of outlaw treasure history.

After personally investing in a treasure hunt off the coast of Florida, Marty Lagina and Craig Tester are thrilled when their search uncovers rare and historical artifacts.

The Laginas are astounded to learn that on a trip to Arizona, Gary Drayton may have gotten to the bottom of one the biggest treasure mysteries of all time, one that has resulted in countless deaths and disappearance for those obsessed with finding it.

Rick and Marty's good friend and world class wreck diver, John Chatterton, heads south to search for a never recovered Spanish ship off the coast of Florida, and Gary Drayton shares with the brothers his most compelling, and valuable, find ever.

Things get dicey when the Laginas deploy Matty Blake to the wild west, where he assists in a dangerous investigation with a local treasure hunter to uncover the secrets of missing Civil War gold.

Marty's fascination is piqued when a fellow energy entrepreneur shares evidence that suggests his Utah ranch has been the Aztec hiding place of Montezuma's treasure for centuries.
