18-9 Using the VRM/EBL
Use one, or both of the VRM/EBL (Variable
Range Markers/Electronic Bearing Lines) to
quickly find the precise range and bearing of
a target.
A VRM can be fixed or floating. Use the VRM
to find the range (distance) to the target.
• A fixed VRM is shown as a thin, dashed,
circle centred around your boat. Use this
to find the distance of a target from your
boat.
• You can move the centre of the VRM away
from your boat; for example, to measure
the distance between two islands. This is
called a floating VRM.
The EBL is shown as a thin, dashed line
extending from the centre of the VRM to the
edge of the radar window. Use the EBL to find
the bearing of the target.
1 From the radar window, press
MENU
then
select VRM/EBL.
If you turn the target trails on, each target
leaves a 30 second trail on the radar screen.
You cannot change the length of the target
trail.
If you turn the target trails off, the targets do
not leave trails.
Note
that if the radar motion mode is set to
true, stationary targets won’t leave a trail.
If the radar motion mode is relative, any
target that is moving relative to your boat will
leave a trail.

5 Select
Adjust
to adjust the positions of
the VRM and the EBL so that you can align
them with the target. Use:
•
and to decrease and increase the
radius of the VRM until it touches the
target to measure the range.
•
and to move the EBL until it
touches the target to measure the
