Introduction to 3D images
Using the 972's 3D screens, you can view
the ocean floor and land information as a
three-dimensional image. You can see
favorite fishing spots, harbor entrances,
and even navigation channels in a full 3D
view, both above and below the water
surface.
You can use the cursor pad to "fly" around
your vessel to observe your surroundings
from a different position.
Note that the first time an area is accessed
for 3D display, it may take some time to
read the data from the disk drive and
process it for display. Blending modes,
especially Photo Blending, require a long
processing time to prepare an image for
display. Once the data is processed, this
display updates quickly.
While every effort has been made to provide
the best elevation data possible, errors in the
source material, data processing and the 3D
presentation may occur. The prudent mariner
will always have official navigation charts for
comparison and as their primary means of
navigation.
