3.2 How the Vertical Mode Works
3.2.1 Overview
The vertical mode shows a vertical section of the horizontal display selected with the
vertical bearing mark. The figure below illustrates the concept of the vertical mode, in
comparison with the horizontal mode. The vertical mode helps you keep fast moving
fish such as bonito and tuna within the sonar beam.
3.2.2 How to set the vertical display
1. Press the MODE key to select [H1] or [H2].
2. Use the trackball to place the cursor at the desired location in the horizontal dis-
play.
3. Press the V1/S or V2 key.
For example, press the V1/S key. Then, the Vertical 1 display appears, and the vertical
bearing marker is displayed in the horizontal display, with V at the tip of the marker as
shown on page 3-3. If both vertical displays are activated 1 or 2 is inscribed at the tip
of a vertical bearing marker.
Note: The TILT control functions as a bearing setting lever for the vertical display1 in
the conditions mentioned below. The bearing of the vertical display1 changes clock-
wise when the
TILT control is pressed upward and counterclockwise when pressed
downward, changing in increments of two degrees.
• The item [Tilt Lever] in the [Display Setting] menu is set to [TILT & V1].
• The vertical screen is chosen in the vertical 2 mode.
