Zoom Width, KHz Sensitivity | Humminbird 580 instruction

Zoom Width

Zoom Width adjusts the width of the Zoom window on 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)

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)
