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.
