AUTOCHART™ ZERO LINE (HUMMINBIRD)

The Zero Line is the place where the water meets the shore. It\'s also the starting point for building your own maps with AutoChart. With these all-important Zero Lines as your foundation, you can begin creating your own accurate and detailed maps of any fishing spot, even where contour coverage doesn\'t exist. Anglers can purchase additional Zero Line Map Cards to view the AutoChart created maps on multiple Humminbird units. Simply export the map from the PC program to the extra Zero Line Map Cards and you\'ll have multiple charts of your favorite fishing spots ready to view on a range of compatible* Humminbird fish finders.
*Optional for select SOLIX, ONIX, ION, HELIX, 1100, 900, 800, and 600 Series models. Compatibility subject to change without notice. All Humminbird units will require a software update for this option.
