Radar (Optional)
109
The strongest returns are shown in red, medium-strength returns in green and weak
returns in blue. Spend some time in good weather watching the radar display while
observing the actual targets being depicted. You will soon learn to identify different
types of targets solely by examining the radar display when in low visibility conditions.
To achieve a radar display with minimal distortion:
Press the radar button to open the radar menu.
Select a
Range
setting, or choose
Automatic
. (Automatic will automatically set a range
that makes best use of the available screen space, based on your zoom level and vessel
orientation).
Raise the gain by increments until you can see all the targets around you.
Too low a gain setting can result in the loss of targets.
If you set the gain too high, you’ll start to see speckling on the screen - lower the gain
just enough to remove the speckling.
Speckling may also be caused by waves or chop around your vessel. If this is the case,
leave the gain alone and instead use the sea clutter setting to remove the speckling.
In congested areas, too high a gain setting may merge separate targets together,
making them unreadable.
Radar Display as Overlay
You can view the radar display by itself, or as an overlay on a nautical chart or
navigation photo. First, turn on the radar display. Then, press the
Mode
button in the
top right corner of the Maestro Navigator screen, and choose
Nautical Chart
or
Navigation Photo
.
