Active Side
(Combo Views only)
Settings: Left, Right; Default = Left
Active Side allows you to select a side of the screen in Combo View. After you choose an active
side, you can apply menu settings and key commands to the view you’ve selected. The Active
Side menu option is only available when a Combo View is on the screen (see
Views: Combo
Views ).
• A green arrow on the Combo View points to the active side.
• When a menu is displayed in the active side, the non-active side of the screen will be
grayed out.
Split Position
(Combo Views only)
Settings: Left, 30, 40, 50, 60, 70, Right; Default = Various
Split Position sets the size of the left side of the Combo View. Each Combo View can be set
individually. The Split Position menu option is only available when a Combo View is on the
screen (see
Views: Combo Views ).
• The number setting indicates the percentage taken up by the left side of the Combo
View.
• Selecting Left sets the left side of the screen to its smallest setting.
SI Side
Settings: Left, Both, Right; Default = Both
SI Side sets which transducer beam from the Side Imaging® beams will be shown on the
display.
SI Sensitivity
Settings: Auto, 1 to 20, where Low = 1, High = 20; Default = 10
SI Sensitivity controls how much detail is shown on the display.
Increase the SI Sensitivity to reveal weaker returns that may be of interest, especially in very
clear water or greater depths. A high SI Sensitivity setting shows more sonar returns from small
baitfish and suspended debris in the water; however if the SI Sensitivity is adjusted too high,
the display may become too cluttered.
Decrease the SI Sensitivity to eliminate the clutter from the display that is sometimes present
in murky or muddy water. If SI Sensitivity is adjusted too low, the display may not show many
sonar returns that could be fish.
