Surface Clutter - Humminbird HELIX 5 SERIES Operation Manual

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.
SwitchFire controls how the sonar returns are displayed in the Sonar Views.
Choose Max Mode to see only raw sonar returns on the display. When Max Mode is selected,
you will see the maximum sonar information available within the transducer beam, so more fish
arches and better jig tracking are shown.
Choose Clear Mode to see less clutter and more fish size accuracy on the display. When Clear
Mode is selected, the clutter is filtered, and sonar returns are interpreted to provide more details
about the objects within the transducer beam, regardless of their location. In other words, a large
arch on the display means a large fish has been detected.
