2.4 Setting the 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 emitted vertically, 90°. To set a tilt angle, operate the TILT control. Watch the tilt angle indication at the top right corner of the screen. The tilt angle can be set in one-degree steps from -5° (upward) to 60° (down- ward). Finding a proper tilt angle is important when searching for fish. Bottom echo and tilt a
