The Curse of Oak Island’s Mastermind? Get to Know Craig Tester Like Never Before

The Curse of Oak Island is one of the History Channel’s most long-running reality shows, and Craig Tester is a big part of it. The series centers on Rick and Marty Lagina, a pair of treasure-hunting brothers who attempt to find various , located in Nova Scotia. Its twelfth season premiered on November 12, 2024, and continues to track the Laginas as they try to uncover the mystery of the titular island.

The Lagina brothers are surrounded by a colorful cast who help them on their quest, and this has led to several Curse of Oak Island spinoffs, including The Curse of Oak Island: Drilling Down and Beyond Oak Island. But while many of these cast members have gone off on their own adventures, Rick and Marty are surrounded by a core group, including Dave Blankenship, Jack Begley, and Craig Tester, and the latter’s importance to the series cannot be overstated.
