EBL/VRM
The electronic bearing line (EBL) is a line from the center of the vessel. The line’s bearing
remains constant as the vessel moves. The variable range marker (VRM) is a user-
controlled range ring that surrounds the vessel.
The EBL/ VRM function is used to measure the distance and bearing from the vessel’s
position to a target. Two different EBL/VRMs can be placed on the radar image.

the Chart page’s context menu.
More information on Radar Overlay is available in the Using chart section of this
