Humminbird Autochart Zero Line Expansion Card

Humminbird AutoChart ZeroLine Micro SD card and SD adapter. Create the most accurate map data possible for your desired body of water—by creating an AutoChart Live map with your own sonar.

Includes a contour map of European lakes for AutoChart Live maps. The bottom map does not include depth data or other information. The ZeroLine card’s large storage capacity allows for longer recordings than the built-in 8-hour storage offered by compatible Humminbird devices without a card.
