network. If a heading sensor is not available, the boat heading is based on
GPS tracking data.
GPS tracking data indicates the direction in which the boat is moving, not
the direction in which the boat is pointing. If the boat is drifting backward or
sideways due to a current or wind, the Radar overlay may not perfectly align
with the chart data. This situation should be avoided by using boat- heading
data from an electronic compass.
If the boat heading is based on data from a magnetic heading sensor or an
automatic pilot, the heading data could be compromised due to incorrect
setup, mechanical malfunction, magnetic interference, or other factors. If the
heading data is compromised, the Radar overlay may not align perfectly with
the chart data.
Echo Trails
The echo trails feature enables you to track the movement of vessels on the
radar display. As a vessel moves, you can see a faint trail

Depending on the radar in use, the settings configured for use in one
radar mode may or may not be applied to other radar modes or to the radar
