Bottom View
Bottom View selects the method used to represent bottom and
structure on the display. Structure ID® represents weak returns in blue and strong returns in red.
WhiteLine® highlights the strongest sonar returns in white resulting in a distinctive outline. This has the
benefit of clearly defining the bottom on the display. See Bottom Presentation for more information.
To adjust the Bottom View:
1. Highlight Bottom View on the Sonar X-Press TM menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Bottom View setting.
