Si Range; Chart Speed; Si Colors - Humminbird 858c Installation And Operation Manual

SI Range

Settings: 6 to 360 feet, or 2 to 120 meters
[International Models only], Default = 150 feet,
50 meters
SI Range sets the deepest range that will displayed in the Side Imaging®
views. The range must be set manually.
Choose a low range number to focus on a shorter distance of the water
column and see greater detail on the screen. Choose a higher range number
to view farther into the water and see an overview of details on the screen.

Chart Speed

Settings: 1- 10, where 1 = Slow, 10 Fastest,
Default = 5
Chart Speed determines the speed at which the side sonar information
moves down the display, and consequently the amount of detail shown. A
faster speed shows more information in the Side Imaging® Views and is
preferred by most anglers; however, the sonar information moves across the
display quickly. A slower speed keeps the information on the display longer,
which allows you to see an entire area.
Side Imaging® X-Press™ Menu
SI Colors allows you to select which color palette you would like to use for
the Side Imaging® display.
