3D/2D Sonar Combo View
3D/2D Sonar Combo View displays a 3-dimensional representation of the bottom next to the
traditional 2-dimensional sonar representation. Depth is always displayed in the upper left
hand corner. The 3D/2D Sonar Combo View is especially useful for evaluating the bottom
terrain from the 3D window while simultaneously viewing the 2D window for structure and
bottom hardness. Refer to the 3D Sonar View and the 2D Sonar View sections for more
information on these views.
The digital readouts in the 3D/2D Sonar Combo View cannot be customized, making
information such as water temperature and voltage unavailable in this view.
