17-9 Using the VRM/EBL

Use one, or both of the VRM/EBL (Variable Range
Markers/Electronic Bearing Lines) to quickly find the
precise range and bearing of a target.
A VRM can be fixed or floating. Use the VRM to find the
range (distance) to the target.
• A fixed VRM is shown as a thin, dashed, circle centerd
around your boat. Use this to find the distance of a
target from your boat.
• You can move the center of the VRM away from your
boat; for example, to measure the distance between
two islands. This is called a floating VRM.
The EBL is shown as a thin, dashed line extending from
the center of the VRM to the edge of the radar window.
Use the EBL to find the bearing of the target.
