Going to a Destination
Using the NAV/MOB key, the GPSMAP 168 Sounder provides four ways to navigate to a destina-
tion: Go To Waypoint, Follow Track (TracBack), MOB (Man OverBoard), and Follow Route navigation.
Once you are actively navigating, you will see a straight line that always runs from the point where
navigaion originated, to the destination. The easiest method for selecting a destination is the ‘Go To’
function, which lets you select a destination waypoint and quickly sets a direct course from your pres-
ent position. If you have a waypoint highlighted on a list or the map, ‘Go To <waypoint name>’ will
appear in addition to ‘Go To Waypoint’. The ‘Go To’ function can be accessed from a list of waypoints
or graphically from the map display.
A dashed circle will appear showing
the alert boundary for the proximity
waypoints.
