Fishnder 350C Owner’s Manual 7
Drift: Sets an alarm to sound when variations in depth at your present location
exceed the specied depth.
Sonar Setup
When you adjust these settings in one sonar view, those adjustments are applied to
the other sonar views automatically.
Select MENU > Setup > Sonar Setup.
Frequency: Sets the frequency to display on the sonar view, when using a dual-
beam transducer.
The 200 kHz frequency shows better detail, has a narrower beam, and is
typically used in shallower waters.
The 77 kHz frequency has a wider beam, so it can be used to cover a larger
area. It can be used as a search tool to locate structures, such as brush piles,
and to see more sh.
Scroll Speed: Sets the rate at which the sonar display moves from right to left.
Using a higher scroll speed shows more detail, especially while moving or
trolling.
Fish Symbols: Displays selected information for the suspended targets.
Noise Reject: Minimizes the appearance of weak sonar returns by increasing noise
rejection.
NOTE: Noise rejection settings must be applied to the split-frequency view
separately from other sonar views.
Surface Noise: Sets whether the device displays sonar returns near the surface of
the water. Hiding surface noise helps reduce clutter.
Color Scheme: Sets the color scheme.
