Note:
You can also specify the level of detail on the chart display (simple, detailed or
extra detailed). For more details, see page 110.
Range rings
Range rings give you an incremental representation of distance from your vessel to
help you judge distances at a glance. The rings are always centred on your vessel, and
the scale varies to suit your current zoom setting. Each ring is labelled with the distance
from your vessel.
To turn range rings on or off
In the Chart application:
1. Press the
PRESENTATION
softkey.
2. Press the
CHART LAYERS
softkey.
3. Select
RANGE RINGS ON/OFF
.
Navionics combined data cards
Some Navionics data cards provide detailed bathymetric information (Fish ‘n’ Chip)
in
addition to standard chart information. You can choose between the standard chart
view, or the view displaying bathymetric contours.
To display bathymetric information (Fish ‘n’ Chip)
In the Chart application:
1. Press the
PRESENTATION
softkey.
2. Press the
CHART LAYERS
softkey.
3. Press the
CHART TYPE
softkey to toggle between
FISH
and
NAV
options.
• The
FISH
option displays bathymetric information.
• The
NAV
option displays the standard chart view.
If you select
FISH
and no data is available for your current position, the databar
displays (FISH) to indicate that you are in that mode but without data.
Showing or hiding waypoints/waypoint information
The system has various options to control the display of waypoints and waypoint
information. You can show or hide all your waypoints and their names or show or hide
waypoints by group or by symbol.
These options are particularly useful when you have placed a large number of
waypoints in a small area and rendered your chart difficult to interpret.
Note:
The show/hide status of a waypoint is a local setting and will therefore only af-
fect the individual display on which you are working.
