Chapter 6: Using the Radar 139
... Using floating VRMs/EBLs
You can use the VRM/EBL float function to measure the range and bearing between
any two points on the radar screen. This function allows you to move the VRM/EBL
centre away from your boat’s position and onto a target. You can then change the
radius of the VRM to determine the distance between two points and change the angle
of the EBL, relative to its new origin, to obtain the bearing.
