Adjust Sonar Display Settings - Humminbird HELIX 9 Operation Manual

DJUST ONAR
Use the instructions in this section to adjust how the sonar returns are shown on the Sonar View, so you can tune into what you want
to see in the display. The settings in this section are optional. You can use the default display settings for the Sonar View, or you
can customize it with your preferences.
Filter Surface Clutter
Use Surface Clutter to reduce the noise that may appear at the top of the view caused by algae and aeration. The lower the setting,
the less surface clutter will be displayed. A higher setting allows more surface clutter to be displayed.
NOTE: You can also adjust the Noise Filter (see Set up Sonar: Adjust the Noise Filter).
1. Main Menu: Press the MENU key twice. Select the Sonar tab.
2. Select Surface Clutter.
3. Press the RIGHT or LEFT Cursor keys to adjust the setting.
Change the SwitchFire Mode
SwitchFire controls how the sonar returns are displayed in the Sonar Views.
1. Main Menu: Press the MENU key twice. Select the Sonar tab.
2. Select SwitchFire.
3. Select Clear Mode or Max Mode.
SwitchFire: Clear Mode
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.

SwitchFire: Max Mode
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.
