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 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.
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 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.
