priority it can be regarded as a

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.
