Turn on/off Fish ID+ Settings
Fish ID+ uses advanced signal processing to interpret sonar returns and will display a fish symbol on the Sonar View when very
selective requirements are met. Also, if Fish ID+ is turned on, you can adjust the sensitivity used for detection and receive alerts with
the Fish ID Alarm turned on.

When Fish ID+ is turned on, fish symbols will be shown on the Sonar View. The color of the fish symbols indicates the sonar beam

When Fish ID+ is turned off, the control head shows only the raw sonar returns on the display.
