Measuring range and bearing to a target
Using the cursor
When you move the cursor on a radar panel the cursor information
window will be activated.
The cursor window shows range and bearing from your vessel to
cursor position.
Range rings
The range rings are displayed at preset distances from the vessel based on the radar
range.
You can use the range ring to estimate the distance between a radar echo and your
vessel.
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 distance and bearing from the vessel’s
position to a target. Two different EBL/VRMs can be placed on the radar image.
