The Humminbird Helix 7 CHIRP MSI GPS G4 is a fish finder with a 7-inch high-definition display. It combines MEGA Side Imaging, MEGA Down Imaging, Dual Spectrum CHIRP sonar, AutoChart Live, an internal GPS and a built-in Humminbird basemap. The display offers many pre-loaded split-screen views.
Dual Spectrum CHIRP 2D sonar uses a Low-Q CHIRP transducer and has two modes. Wide Mode gives maximum coverage, and Narrow Mode focuses on fine detail. MEGA Side and Down Imaging show up to 125 feet to either side of the boat and 125 feet below it, with up to 3X more detail than standard imaging sonar.
The basemap shows buoys, day markers, hazards, marinas, contours and depth markers. It includes charts of more than 10,000 lakes, plus coastal coverage for the continental U.S. AutoChart Live creates real-time maps of depth contours, bottom hardness and vegetation as the boat moves. The unit is operated with a keypad and softkey controls through a menu system.
