Sonar Page and Flasher
The most intense, constant signal on the Flasher is the actual depth and bottom.
The colors indicate the different strength of the signals.
• A soft bottom (such as silt or mud) creates as signal that is narrow and
more faint.
• A hard bottom (such as sand or rock) creates a signal that is wider.
