Change the SwitchFire Mode
SwitchFire controls how the sonar returns are displayed in the view.
1. With a 2D Sonar View displayed on-screen, tap Sonar (2D) in the status bar, or press the MENU key once.
2. Select SwitchFire.
3. Select Clear Mode or Max Mode.
SwitchFire: Clear Mode
Tap to open the SwitchFire menu in the status bar.
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.
QUICK TIP! This setting can also be changed in the status bar menu. See the illustrations above.
SwitchFire: Max Mode
Tap to open the SwitchFire menu in the status bar.
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.
