2.6 Choosing a 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). Choose tilt angle depending on target fish.

For surface fish choose a narrow angle (about 5°) and for bottom fish, a wide angle (about

40°).
