Graph Tab
The Graph tab enables you to determine the appearance of the Sonar Pages.
The following settings are available:
•Fish Symbols—sets how the Fishfinder interprets suspended targets and background information. If you select a fish symbol, the Fishfinder identifies some returns for you by replacing them with fish symbols (in large, medium, and small sizes based on the size of the sonar return). If you are using dual beam, fish symbols from the narrow beam
(directly underneath your boat) are solid, and the returns from the wide beam (out to the sides of your boat) are hollow.
(default) the Fishfinder does not interpret the sonar return data.
suspended targets appear as symbols. No background information appears.
suspended targets appear as symbols with no background information shown. The target depth is indicated.
Using the Fishfinder 340C > Using the Main Menu

•Scale—controls the depth scale shown vertically along the right side of the graph. The settings are Overlay (default), in the Corners, Basic scale, or No Scale.
•Custom Range—allows you to specify a custom viewing range or scale. When On, this range appears as Custom in the Range setting. The left value is the top of the scale and the right value is the bottom of the scale.
•Color Scheme—sets the colors for the Sonar and Flasher Pages. The default setting is Classic White.
•Temperature and Water Speed—hides or shows temperature and water speed on the Sonar Page. When set to Auto, the Fishfinder automatically shows this information if it is received from a capable transducer.
