Surface Clutter
(Advanced)
Surface Clutter adjusts the filter that removes surface clutter noise caused by algae and
aeration. The lower the setting, the less surface clutter will be displayed. The Surface
Clutter menu choice is available when User Mode is set to Advanced (see Setup Menu
Tab: User Mode).
NOTE: If the Surface Clutter menu is set to lower than 5, it will also decrease the displayed signal
strength of targets (fish) close to the surface.
To change the Surface Clutter setting:
1. Make sure you are in Advanced User Mode, then highlight Surface Clutter on the
Sonar main menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Surface Clutter
setting. (Low = 1 to High = 10, Default = 5)
