What can you say about David Trotter?  David has given more presentations than any other speaker at our annual Shipwrecks Symposium.  He just keeps discovering shipwrecks and as long as he does, we’ll keep inviting him back!

David Trotter is a renowned shipwreck discoverer, deep diver, author, lecturer and photographer.  In over 30 years of diving, he has been the first to locate, identify and document 70+ Great Lakes shipwrecks.  His shipwreck discoveries and programs have been featured on television and in newspapers throughout the U.S. and Canada and in Gerry Volgenau’s new book “Shipwreck Hunter”.  He has written several articles on Great Lakes shipwrecks that have been published in historical journals and national scuba diving publications.

Through Undersea Research Associates, founded to present the Great Lakes community with an electronically sophisticated means of underwater search and survey for archeological and commercial purposes, he presents visual underwater time capsules of marine history.  Utilizing state-of-the-art side scan sonar, with outstanding skilled operators, the organization offers high resolution bottom profiling at depths to 1,000 feet, underwater site survey and underwater photographic documentation.

Cutting Across Time-30 Years of Adventure

The idea started with the recently published book, Shipwreck Hunter………to share the early images and the excitement of being the first to explore unique, one of a kind Great Lakes shipwrecks that represent our Great Lakes Marine History.

In the beginning, positioning systems such as Loran C and Global Positioning Systems (GPS) did not exist.  Then the convergence of positioning systems and the application of sidescan sonar underwater survay made profound changes in Great Lakes exploration.

The world of exploratrion, for shipwreck hunters and shipwreck divers, has now become a dive into Great Lakes Marine History; our History.  The Great Lakes is one of the last unexplored realms where people of modest means, you and I, can truly experience discovery and “virgin” exploration, and share the adventure with others.

From discoveries in the 70’s to the most recent new discoveries in 2007, this program is a great visual experience to delight historians, shipwreck divers and adventurers.  It is one hell of a ride!
