Entering An Own Ship Position Mark; Deleting An Event Mark, Own Ship Position Mark - Furuno FSV-84 Operator's Manual

2. HORIZONTAL MODE
Plotting an event mark on the display is equivalent to dropping a buoy with an
anchoring chain that extends from surface to bottom. The buoy is fixed at its
geographical location, but the marker on the display moves to a point where
present beam plane intersects the anchor chain of the buoy as ship moves or
the tilt angle is changed. This can be said about marks as well such as fish mark
and trackball mark.
