Conguring the Sonar Page

Using the Flasher

If you prefer the appearance of asher sonars, select the Flasher function on the

Conguration window for the Sonar Page. It provides an almost instantaneous

return of what is below your boat.

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.
