“Why is it important to upgrade your electronics? Your depthfinder is like a computer at home. Upgrading provides software updates and new features that lead to better performance. Keeping your unit current gives you maximum performance.”
“Go to Humminbird.com with your serial number, go to my account, create the account, and it will give you the current software number. If you need an update, download it to an SD card, stick that card in your locator, start the upload process, and you’re ready to go.” –J.E. VanNatta, Arkansas, Humminbird Pro Staff.
