Bottom Discrimination Function
The bottom discrimination function analyzes the bottom composition (rocks, gravel, sand,
mud) and shows the results in a colorful graphic display. This feature requires a
transducer that supports bottom discrimination, or Bottom Discrimination Sounder BBDS1.
The bottom material information appears at the bottom of the screen when the bottom
discrimination function is turned on. The information can be displayed in all window sizes,
including single frequency display and dual frequency display.
