Sounds an alarm when the unit detects what it

Graph
Fish ID
The Fish ID setting determines how the graph displays underwater
targets and background information. If Fish ID is set to Off, the
unit displays all of the available information about the underwater
environment. If a fish symbol is selected, the graph displays only
the information related to that symbol (large, medium, and small
sizes). In wide beam, fish detected toward the outside of the beam
are displayed with a hollow symbol. Fish detected directly under the
boat are solid.
—All available information is displayed. (default)
— Suspended targets appear as symbols. No background
information is displayed in this mode.
—Same as above with target depth displayed.
— Suspended targets appear as symbols. In this mode
background information is still displayed making fish
identification easier.
—Same as above with target depth displayed.
Beam
The Beam setting allows the selection of a Narrow Beam or Wide
Beam for the transducer. A narrow beam provides higher detail
structure returns of a smaller bottom area. The wide beam shows a
larger fish return area with poorer detail of non-bottom structure.
