You can use the Free EBL and Fixed EBL commands to draw electronic bearing
lines either centered on own ship or at any location on the display. The Fixed
EBL command draws an electronic bearing line which centers on own ship’s
location. The Free EBL command will allow you to obtain the range and bearing
between any two points on the display.
