2.6 Selecting the Tilt Angle
The tilt angle shown 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 emitted vertically, 90°.
To 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.
The tilt angle can be set in increments of 1°
from 0° to +5° (upward) to 0° to 90°
(downward).
Select tilt angle depending on target fish. For
surface fish select a narrow angle (about 5°)
and for bottom fish, a wide angle (about 40°).
