Copying Humminbird Map Cards

All Humminbird map cards (LakeMaster and CoastMaster) are copyright protected, and the contents will not work on any card other than the original. It is also not advised to copy the original files on your card or write to it, as you may accidentally overwrite or remove essential files on the card, rendering it useless.

The AutoChart Zero Lines card is also copyright protected, but is made to be written to from your compatible Humminbird unit or AutoChart PC software. However, the original folder (LkMaster) included on a newly purchased card must never be altered or deleted.
