SI Range Lines
(Advanced, Side Imaging® View only)
Settings: On, Off; Default = Off
SI Range Lines
divide each side beam range into 4 equal sections on the display. SI Range
Lines can be used to interpret the location of objects on the display. You can turn SI Range Lines
On (visible) or Off (hidden).
NOTE:
The range numbers are estimated and should not be used for measurement.
Noise Filter
(Advanced)
Settings: Off, Low, Medium, High1, High2, High3; Default = Low
Noise Filter
adjusts the sonar Noise Filter to limit interference on the display from sources such
as your boat engine, turbulence, or other sonar devices.
The Off setting removes all filtering. Low, Medium, and High1, High2, High3 settings add
progressive filtering of the sonar returns. High1, High2, and High3 are useful when there is
excessive trolling motor noise, but in some deep water situations, the High settings may actually
hinder your unit’s ability to find the bottom.
