The Humminbird autochart leaves no waters uncharted. Proprietary software from the new Humminbird AutoChart uses your Humminbird’s sonar returns and GPS to build your charts. Simply record that information onto the AutoChart Zero Lines map card (included), import that data into the AutoChart PC program which will convert it into a lake map. Once complete, transfer your new custom map back onto the AutoChart Zero Lines map card and it’s ready to display on any compatible Humminbird. No subscriptions. No hidden fees. No need to submit your data and wait weeks for a finished chart. AutoChart does it instantly - and your data is kept private, so your competition is none the wiser. Operates with ONIX, ION, 1100, 900, 800, Helix 7, 9, 10, and 12.
