Join Joe Van Wagnen, Mark Gammage and other shipwreck enthusiasts as they research, locate and explore new and existing shipwrecks in the Great Lakes using technology such as side scan sonar, diver POV and Remotely Operated Vehicles (ROV). Our purpose is to share and educate our viewers on Great Lakes shipping history viewed through the eyes of a diver or a ROV. In many cases these time capsules are just the way the were when they sunk over a century ago, giving us a glimpse into the past.
