Tester And 'The Curse Of Oak Island' 

One of the most famous reality TV shows, The Curse of Oak Island is about the Lagnia brothers who do their best to find treasures and artifacts in the infamous Oak Island located in Canada. The documentary-style reality TV show first aired in 2014 and is still going strong seven years later. 

Tester is mostly known for his involvement in the show as both producer and crew member. Following the footsteps of his friend Marty Lagnia, Tester joined him on Oak Island to find the hidden treasure.

Being a mechanical engineer, Tester is an expert in drilling and resistivity. Hence, he started as a crew member where he used his engineering skills to know where to dig for treasures in Oak Island. He has appeared in 97 episodes of the show.
