track recording
Your GP450X can record a log of your vessel’s movements . Track
points are stored in memory at regular intervals and displayed
on the screen as a trail extending behind your vessel . The
points are stored at distance intervals determined by settings
in the Plotter Setup menu . A shorter interval allows more track
points to be recorded which provides a more detailed log but
uses more memory resulting in a shorter storage time . A longer
interval will allow much longer recordings but there will be less
detail . Once the track memory becomes full, the current track
log will overwrite the oldest track points with newer points . If
track recording is not required it can be turned off .
WayPoINts

three ways;
• from the cursor position,
• from your vessels own current position or
• by manually entering a known latitude and longitude.
