Figure 7-11 Event mark description

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

Erasing an event mark

Open the data setting window (sub panel 2) and select DELETE MK. Press appropriate EVENT key to erase mark.
