Press once or more until the Setup
menu is displayed, then select Chart:
Rotation
The options for chart rotation are:
North up: North is always at the top of
the chart display.
Track up: The chart is rotated so that the
boat direction is to the top of the display.
This option is useful for navigating narrow
harbours or rivers. The TRACKFISH asks for
a course deviation resolution; this is how
much the boat direction needs to change
to make the chart redraw.
58
frequently, increase the course
deviation setting.
Course up: This option is only available
if the boat is navigating to a destination.
The chart is rotated so that the plotted
course to the destination is vertical.
Palette
Select the colour scheme for the LCD display.
The options are:
Normal
Sunlight: Brighter colours, more visible
in sunlight.
Night: Reversed colours for night, to
preserve night vision.
Map datum
TRACKFISH GPS positions are based on a
worldwide reference (datum) known as WGS
84. Most paper charts are based on WGS 84.
However, some paper charts are based on
other datums In these cases, the latitude
and longitude coordinates of objects on the
TRACKFISH chart display are different to the
latitude and longitude coordinates of these
objects on the paper chart. This applies to
all objects, such as the boat, waypoints,
tracks, lines of latitude and longitude and
cartographic features such as land, rocks,
buoys and depth contours.
Use Map datum to select the TRACKFISH map
datum to match the datum of the paper chart.
Then, the latitude and longitude coordinates
of objects displayed on the TRACKFISH
will change to match the corresponding
coordinates on the paper chart.
Setting map datum
In the Chart setup menu, select Map

datum.
2 Select the map datum for the paper chart
you are using.
3 If you select a datum other than WGS 84
the TRACKFISH asks if you want to apply the
NMEA datum offset (see below).
