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.
