17-8 Turning the target trails on or off
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.

17-9 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 centerd •
around your boat. Use this to find the distance of a
target from your boat.
You can move the center 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 center of the VRM to the edge of the radar window.
Use the EBL to find the bearing of the target.
