Graph Tab - Garmin Fishfinder 340C Owner's Manual

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.

the Corners, basic scale, or No Scale.

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.
