Down Imaging™ View
(858c HD DI, 958c HD DI, 898c HD SI, and 998c HD SI only)
Down Imaging™ models (858c HD DI, 958c HD DI)
use the razor-thin,
high-definition profiling beams to produce the detailed sonar data that you
see on the display.
Side Imaging® models (898c HD SI, 998c HD SI)
display the down beam
portion of the data from the Side Imaging® beams. The Down Imaging™
results are displayed in a “picture-like” image on the screen in 2D format.
Sonar returns are charted on the right side of the display. As new
information is received, the historical information scrolls left across the
display. See
What’s on the Down Imaging™ Display
for more information.
