OPERATING INSTRUCTIONS > THE SETUP MENU

Shallow

The Shallow Alarm sounds a warning at a determined depth between 1 and 900 ft.

Deep

Fish Alarm

Sounds an alarm when the unit detects what it determines to be a fish. The alarm selections are: Off (default) or On.

Graph

Fish ID

The Fish ID setting determines how the graph shows underwater targets and background information. If Fish ID is set to Off, the unit shows all of the available information about the underwater environment. If a fish symbol is selected, the graph shows only the information related to that symbol (large, medium, and small sizes). In wide beam, targets detected toward the outside of the beam are indicated by a hollow fish symbol. Targets detected directly under the boat are indicated by a solid fish symbol.
