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.
(-10 to +10, Default = 0)

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®)

the Sonar Zoom View.
To change the Zoom Width Setting:
1. Highlight Zoom Width on the Sonar main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Zoom Width
setting. (Narrow, Medium, Wide, Default = Wide)
