F136 Lake Amistad Fishing Electronic GPS SD Card for Humminbird Machines
F136 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 F136, Lake Amistad map. Your electronic GPS unit will now have the F136 map GPS coordinates for fishing spots, reefs, state and federal parks, marinas, boat ramps and other points of interest. Lake Amistad is shared by Texas and Mexico with the submerged Rio Grande River running down the middle of the lake. Del Rio, Texas is the main town on the Texas side. 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.
