The Event Mark

The event mark is useful for finding the horizontal range, depth and bearing to a location some distance from current position. This function requires speed and heading inputs.

There are two types of event marks: event mark 1 and event mark 2. 10 of each type of mark can be displayed. The unit marks the latest one by () for event mark 1 and by () for event mark

2.Older event marks are displayed by a cross plus event number (event mark 1) or an inverted Y with event number (event mark 2). When you enter more than ten event marks, the unit erases the oldest mark, one by one.
