Si Side; Si Sensitivity - Humminbird 700 Series Operating Manual

SI Side sets which transducer beam from the Side Imaging® beams will be
shown on the display.
SI Sensitivity controls how the sonar returns are displayed on the
Side Imaging® Views.
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.
