Measuring using VRM/EBL
Variable Range Markers (VRM)
A Variable Range Marker (VRM) is a circle centred
on your vessel’s position and fixed with respect to
the heading mode. When this circle is adjusted to
align with a target, its range from your vessel is
measured and displayed on the Radar context menu
when you select the VRM with the cursor.
Electronic Bearing Lines (EBL)
An Electronic Bearing Line (EBL) is a line drawn
from your vessel to the edge of the window. When
this line is rotated to align with a target, its bearing
relative to your vessel’s heading is measured and
displayed on the Radar context menu when you
select the VRM with the cursor.
The VRM/EBL are combined to measure both the
range and the bearing of the specified target.

Measuring using floating VRM/EBL
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 vessel’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.
