Variable Range Marker
A Variable Range Marker (VRM) is a circle of variable radius cen-
tred on your vessel’s position.
You can use the VRM to measure the distance from your vessel to
a selected object by adjusting the radius of the marker so that it
intersects the object’s position.
The range is displayed on the ADJUST VRM softkey label when
you highlight the VRM.
Electronic Bearing Marker
An Electronic Bearing Line (EBL) is an on-screen marker drawn
from your position to the edge of the window.
When this line is rotated to align with a target, the bearing relative
to your current heading is measured and displayed on the ADJUST
EBL softkey label.
The data is also displayed if you select the EBL with the cursor.
To change the EBL reference from relative to magnetic or true, see
page 139.

ing simultaneously:
