Copying Humminbird map cards

All Humminbird maps are copyright protected and will not work on any card other than the original. It is also not advised to try to copy your LakeMaster card as you may accidentally overwrite the map file on the card which will render it useless. You can make a backup copy of the map file on your computer for archival purposes only.

This is also true for the Humminbird Zero Line card, it requires a special encryption.
