21 Use the radar
This section explains the Radar screen and status bar, and the radar orientation,
and explains how to:

•
change the radar orientation

If you prefer to see the Radar screen overlain on your Chart screen, rather than use
it as an individual feature, see "Overlay the radar" in the Chart section. The radar
overlay can help you to quickly identify objects that are not on the chart, such as
other vessels, and to check that the GPS data is accurate. The heading sensor must
output data at a 10Hz update rate to ensure accurate synchronization of the chart
and the radar.
