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 a signal that is narrow and more

faint.

• A hard bottom (such as sand or rock) creates a signal that is wider.
