Position track
If you wish to establish a marker on a geographical position, use the
standard marker. If you wish to start position tracking, press
on the Operating Panel, or give a selected marker priority. When
Track
a marker is given priority it can be regarded as a position track.
The phrase position is used to identify a fixed echo in the display
presentation that you wish to act upon. The echo may for example be from a
shallow, reef or rock. You must decide which echoes that shall be classified as
positions, and whether you shall start position tracking.
The position track locks on a position defined by its latitude, longitude and depth. The
bearing and tilt settings are automatically adjusted to compensate for the movements of
your vessel. The bearing line is automatically locked on the object to reflects its bearing.
The marker is stationary. If the echo moves in the display presentation the marker will not
follow. If you change the tilt and bearing settings manually, the position track is disabled.
Note
The priority is identified with a "P". You can only give priority status to one object. If
you create a new marker and give this priority, the position track is disabled. The same
applies if you start a new target track.
Relevant information about the priority target can be found in the lower left corner of
the view. If you think the text is small and hard to read, double-click on the text field.
This will increase the text size.
