Showing AIS Vessels on the Radar Screen
AIS requires the use of an external AIS device and active transponder signals from other vessels.
You can configure how other vessels appear on the Radar screen. If any setting (except the AIS display range)
is configured for one radar mode, the setting is applied to every other radar mode. The details and projected
heading settings configured for one radar mode are applied to every other radar mode and to the Radar
Overlay.
1. From the Home screen, select Radar.
2. Select Cruising, Harbor, offshore, or Sentry.
3. Select Menu > other Vessels > AIS Display Setup.
4. Complete an action:
• Select AIS Display Range to indicate the distance from your location within which AIS vessels appear,
and select a distance.
• Select Details > Show to show details about AIS-activated vessels.
• Select Projected Heading, enter the projected heading time for AIS-activated vessels, and select Done.
• Select Trails to show the tracks of AIS vessels, and select the length of the track that appears using a
trail.
VRM and EBL
The variable range marker (VRM) and the electronic bearing line (EBL) measure the distance and bearing
from your boat to a target object. On the Radar screen, the VRM appears as a circle that is centered on the
present location of your boat, and the EBL appears as a line that begins at the present location of your boat and
intersects the VRM. The point of intersection is the target of the VRM and the EBL.

The VRM and the EBL configured for one mode are applied to all other radar modes.
