3.8 Waypoints
In navigation terminology, a waypoint is a particular location on a voyage whether it be a
starting, intermediate or destination point. A waypoint is the simplest piece of information
your equipment requires to get you to a destination, in the shortest distance possible.
This unit has 999 waypoints into which you can enter position information. You may enter a
waypoint five ways: at own ship position, at MOB position (see page 1-11 for details), by
cursor, by range and bearing, and through the waypoint list (manual input of latitude and
longitude).
