Down Imaging® View
(859ci HD DI, 959ci HD DI, 899ci HD SI, and 999ci HD SI only)
Down Imaging® models (859ci HD DI, 959ci 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 (899ci HD SI, 999ci 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.
• Coverage: The Down Imaging® coverage is always very thin front to
back, and the side to side width can be adjusted (see Sonar Menu
Tab: Down Imaging® Beam Width).
• Down Imaging® X-Press™ Menu: Press the MENU key once to access
the Down Imaging® X-Press™ Menu. You can set the sensitivity of the
sonar to see more or less detail, the chart scrolling speed, and the
display color palette (see Down Imaging® X-Press™ Menu).

the Down Imaging® View will freeze and a cursor will appear on the
