F122 Lake Somerville Fishing Electronic GPS SD Card for Humminbird Machines

F122 coordinates for Humminbird Machines.

This little SD card plugs directly into your electronic GPS unit and downloads all fishing information with GPS coordinates taken from the hard copy Hook-N-Line F122, Lake Somerville map. Your electronic GPS unit will now have the F122 map GPS coordinates for fishing spots, reefs, state and federal parks, marinas, boat ramps and other points of interest for Lake Somerville. Once you have downloaded all our coordinates, each spot will display as a symbol and a label shown on top of the built-in map already in your electronic GPS unit.*  Please note that only fishing information having GPS coordinates will be downloaded. After downloading is complete, the SD card can be removed and kept in a safe place.

* Your GPS unit should come with a built-in map of your fishing area.
