Bathymetric maps are essential "tackle" for locating drop-offs, structure, and other areas that hold fish. Trophy Maps are a superior to other maps because they display the full range of depth contours, geographic latitude and longitude grids, boat ramps, light houses, pier heads, buoys and more. Trophy Maps allow you to reference the geographic grids to estimate locations over your preferred fishing area. Once you have estimated a specific location you can insert the coordinates into a Global Positioning System (GPS) and go to selected location. Trophy Maps are constructed with the most recent and detailed data available for the Great Lakes Region. Trophy maps are easy to use, informative, durable and waterproof. Trophy Maps are currently available for areas of Lake Michigan, Lake Huron and Lake Erie. Custom bathymetric maps are available by request for all of the Great Lakes including Lake St. Clair.
