2.2.5 Fish Finder Display
The fish finder screen converts the reflection signal of the supersonic wave launched in four directions
into 16 colors according to strength, and displays the water inside.
Because the supersonic wave is turned in four directions (Fore Starboard, Fore Port, After Starboard,
After Port), each detection result can be displayed by division (four screens) into four, and, in addition,
two screens and one screen displays can be selected.
The fish finder screen is displayed with the [FISH] key. The fish finder screen includes three screens; fish
finder 1(one direction display), fish finder 2(two direction display), and fish finder 3(four direction display).
The selection of the screen is set by the menu. (*501)
