Target Wakes
You can see the direction and speed with which targets are moving
relative to your vessel by selecting the target wakes display option.
When wakes are switched on, the target is displayed at the brightest
level and the previous positions of targets are retained at successively
fainter levels on the screen. You can select long, medium or short
wakes, which retain information from previous scans at a reduced
video level.
You can clear existing wakes from the display by clicking the Clear
Wakes Functionbar button. When wakes are switched off, no new
wakes are displayed and existing wakes are cleared.
Measuring Range and Bearing Using VRM/EBL
The Pathfinder Plus Radar display allows you to specify up to two
Electronic Bearing Lines (EBL)s each with an associated Variable
Range Marker (VRM), using the VRM/EBL button on the Pathfinder
Panel.
A standard VRM is displayed as a circle with its center on your
vessel's position, and its EBL is displayed as a line from the origin to
the edge of the radar picture display (Figure 5-8).
