2.4.2 Automatic tilt
The AUTO TILT key automatically scans the tilt angle within the selected width. This
is useful when you want to find the center depth of a school of fish. Wide tilt angle is
activated from the [Auto Tilt] on the [Others] - [Display Setting] menu.
1. Press the AUTO TILT key to select auto tilt angle desired. Each time the key is
pressed the auto tilt angle changes in the following sequence.
2. If necessary, operate the TILT control to change center tilt angle.
In automatic tilt, “AUTO” is displayed at the top right corner. To disable automatic
tilt, select OFF at step 1.

For example, when the RANGE control, TILT control and AUTO TILT key are set to
800 m, 8° and width (1) respectively, the tilt angle changes at each transmission as
follows: 8°
→ 9° → 8° → 7° → 8°.
