The available Graph sub tab options are:
• Color Scheme—sets the colors for the Sonar and Flasher Pages.
• Fish Symbols—sets how the Sonar Page interprets suspended targets
and background information. If you select a fish symbol, the
GPSMAP 3005C 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.
Symbols are turned off.
Suspended targets appear as symbols. No background
information appears
Same as previous with the target depth shown.
Suspended targets appear as symbols. Background information
appears, making the distinction between fish and structure easier.
Same as previous with target depth shown.
• Scale—controls the appearance of the depth scale shown vertically along
the right side of the graph. You can configure the depth scale to appear in
one of four different ways: as an Overlay, in the Corners, Basic, or No
Scale.
Water Temp Sub Tab
The Water Temp sub tab enables you to control the temperature log (if your boat
is equipped with a temperature transducer/sensor). The graph reads from right to
left, so that the most recent temperature measured appears on the far-right side
of the log. The dotted lines within the graph indicate intervals in the temperature
scale and the duration of time.
The following settings are available:
• log and Graph Scale—sets the temperature range (in degrees) to
display on the log and on the Sonar Pages. Select Auto to have the unit
automatically determine the best range, or select a Span of 2, 4, 6, 8, or 10
degrees.
• log Duration—sets how fast or slow the temperature log scrolls (the
shorter the time duration, the faster the temperature log scroll). Select a
duration from 1 Minute to 2.5 hours. 10 Minutes is the default.
• Temperature log—records the water temperature as you move through the
water so that you can look for temperature changes over a period of time.
