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 in increments of 1 from -5 (upward) to
90 (downward). The tilt angles for the horizontal1 and horizontal2 modes can be
adjusted independently. The FSV-30 provides 90 of vertical detection.
2.4.1

Setting the tilt angle

To manually set a tilt angle, operate the [TILT] control. Watch the tilt angle
indication and tilt angle indicator at the top right corner 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: The TILT control functions as a bearing setting lever in the following
conditions:
TILT LEVER in the DISPLAY SETTING menu is set to "TILT & V1."
The vertical display is chosen in the vertical mode.

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 fish school.
1. Press the [AUTO TILT] key to select auto tilt angle desired. Each time the
[AUTO TILT] key is pressed the auto tilt angle changes in the following
sequence.
Range
60, 100
150, 200
300, 400
500, 600
800
1000
more than 1200
2. Auto tilt begins, with the tilt angle set with the [TILT] control as the center tilt
angle.
3. If necessary, change center tilt angle with the [TILT] control.
