2.4 Tilt Angle
The tilt angle shows the direction to which the sound wave is emitted. When the sound
wave is emitted horizontally, the tilt angle is said to be 0° and when vertically, 90°. The
tilt angle can be set between -5° (upward) to 90° (downward), in increments of 1°. The
tilt angles for horizontal 1 and horizontal 2 modes can be set independently of one an-
other.
2.4.1 How to set the tilt angle
To set a tilt angle manually, operate the TILT control. Watch the tilt angle indication
and tilt angle indicator at the top right corner of the screen. The tilt angle is shown next
to “T“ at the top right of the screen.
Select tilt angle depending on target fish. For surface fish select a shallow angle
(about 5°) and for bottom fish, a deep angle.
Note 1: In the factory default condition, the tilt angle can also be adjusted by rolling
the scrollwheel.
Note 2: The tilt angle can also be adjusted from the tilt angle indication. Put the cursor
on the tilt angle indication to highlight it in yellow then roll the scrollwheel.
Note 3: The TILT control functions as a bearing setting lever when the following con-
ditions are met: [Tilt Lever] in the [Display Setting] menu is selected to [Tilt & V1], and
the vertical display is chosen in the vertical mode.
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.
