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 main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Bottom View
setting. (Structure ID®, WhiteLine®, Default = Structure ID®)

Zoom Width adjusts the width of the Zoom window on
the Sonar Zoom View.
To change the Zoom Width Setting:

83 kHz Sensitivity
(Advanced)
83 kHz Sensitivity changes the sensitivity of the 83 kHz beam. Increasing the 83 kHz
Sensitivity will display additional weak returns and decreasing the 83 kHz Sensitivity will
display fewer weak returns. The 83 kHz Sensitivity menu choice is only available when
User Mode is set to Advanced (see Setup Menu Tab: User Mode).
NOTE: 83 kHz Sensitivity is particularly useful for adjusting the sensitivity of the 83 kHz sonar
returns in the 200/83 kHz Split Sonar View. The 83 kHz sensitivity can be adjusted without
affecting the sensitivity of the 200 kHz returns shown in the 200 kHz sonar window.
To set the 83 kHz Sensitivity:
1. Make sure you are in Advanced User Mode, then highlight 83 kHz Sensitivity on
the Sonar main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to set the 83 kHz Sensitivity.
