fixed and floating.
fixed and floating.
The fixed EBL is a blue line from your present position (Point
“A”) to Point “B.” You can move Point B on the screen using the
cursor pad as described below. At the end of the line, a blue
circle called a variable range marker (VRM) surrounds the area
of interest. Another VRM circle surrounds your vessel’s
position.

position.

The VRM at your position (Point A) is called VRM A. The VRM
at Point B is called VRM B. You can change the size of each
VRM, to use it for measuring distances from Point A or Point B
to any point of interest on the screen.
at Point B is called VRM B. You can change the size of each
VRM, to use it for measuring distances from Point A or Point B
to any point of interest on the screen.
The floating EBL is a pink line between any Point A and any
Point B. It’s similar to the fixed EBL, except that Point A can
also be moved to allow measuring distances between any two
points on the screen. Again, there’s a variable range marker at
each end of the line.
