    The LakeMaster Advantage

    The unmatched accuracy and detail of Humminbird LakeMaster give you a serious edge. Patented features include the ability to select and highlight a specific depth range, the option to shade shallow water ranging from zero to 30 feet, and the power to synchronize depth chart contours and shorelines with the current water levels of lakes, reservoirs and rivers. With these exclusive features and more, you’ll have everything you need to make your time on the water more productive.

    Coverage and Compatibility

    Humminbird® LakeMaster® Great Plains, Version 1 combines many of the best fishing waters for Iowa, Illinois, Kansas, Missouri and Nebraska, all on one map card.

    The Difference is PLUS

    The new PLUS series allows for aerial image overlay on high-definition waters giving you the ability to use quality aerial photography to view the entry and exits of creek channels, see how far a reef or weed line extends, and pick out shallow water rock piles, steep drop-offs or other features of the lake you’ve been missing from traditional maps.


    PLUS also brings the groundbreaking technology of Follow the Contour to your fingertips. When combined with a compatible i-Pilot® Link™ system, your map card allows your boat to automatically follow a path directly on or offset from any contour, so you can focus on fishing. Find more info about i-Pilot Link here.
