Markers
One or more markers can be placed in the view to identify specific echoes. Markers are
shown as small triangles. Once an echo has been provided with a marker in the display
presentation it is regarded as an object.
Markers
A
Priority marker
B
Coverage plot
C
Variable range ring
D
Horizontal dotted lines show the
E
depth intervals.
The range rings are shown as
F
dotted curves.
Note
When target tracking is activated,
bearing and tilt are automatically
adjusted to follow the movements of
the tracked target.
You can give priority status to one marker to identify the relevant object as the most
important target or position. Bearing and tilt are automatically adjusted to focus on
the priority marker.
Each marker is numbered sequentially. Use
marker symbols in the currently active view. This function is located on the
menu.
Objects Visual Objects
The marker is stationary. It has a specified range, bearing and depth related to your own
vessel. If the echo moves in the display presentation the marker will not follow.
The SN90 system automatically copies markers generated in the Horizontal view to
the Vertical view and vice versa.
Tip
The menu controls which graphical elements that are shown in the
Visual Objects
different views. These graphic elements include markers, vectors and targets that are
tracked. The majority of the functions are "on/off" buttons to enable or disable these
graphic elements in the various views.
