Bottom View<br />
Bottom View selects the method used to<br />
represent bottom <strong>and</strong> structure on the display. Structure ID® represents<br />
weak returns in blue <strong>and</strong> strong returns in red. WhiteLine® highlights the<br />
strongest sonar returns in white resulting in a distinctive outline. This has<br />
the benefit of clearly defining the bottom on the display. See Bottom<br />
Presentation for more information.<br />
To adjust the Bottom View:<br />
1. Highlight Bottom View on the Sonar Main Menu.<br />
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the<br />
Bottom View setting. (Structure ID, WhiteLine, Default = Structure ID)<br />
Zoom Width<br />
(Sonar Zoom View only)<br />
Zoom Width allows you to control the width of the Zoomed Sonar (the lefth<strong>and</strong><br />
side of the screen).<br />
To change the Zoom Width:<br />
1. Highlight Zoom Width on the Sonar Main menu.<br />
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the<br />
width of the Zoomed Sonar. (Narrow, Medium, Wide, Default =<br />

83 kHz Sensitivity<br />
(Advanced)<br />
83 kHz Sensitivity changes the sensitivity of the 83 kHz beam. Increasing the<br />
83 kHz Sensitivity will display additional weak returns <strong>and</strong> decreasing the 83<br />
kHz Sensitivity will display fewer weak returns. The 83 kHz Sensitivity menu<br />
choice is only available when User Mode is set to Advanced (see Setup<br />
Menu Tab: User Mode).<br />
To set the 83 kHz Sensitivity:<br />
1. Make sure you are in Advanced User Mode, then highlight 83 kHz<br />
Sensitivity on the Sonar main menu.<br />
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to set the 83 kHz<br />
Sensitivity. (-10 to +10, Default = 0)<br />
455 kHz Sensitivity<br />
(Advanced, with optional purchase QuadraBeam<br />
PLUS transducer)<br />
455 kHz Sensitivity adjusts the sensitivity of the 455 kHz beam. Increasing<br />
the sensitivity will display additional weak returns <strong>and</strong> decreasing the<br />
sensitivity will display fewer weak returns. A QuadraBeam PLUS<br />
transducer must be attached to the <strong>Fish</strong>ing System. The 455 kHz Sensitivity<br />
menu choice is available when Transducer Select is set to QuadraBeam (see<br />
Sonar Menu Tab: Transducer Select) <strong>and</strong> User Mode is set to Advanced<br />
(see Setup Menu Tab: User Mode).<br />
