180° / Vertical (Option)

When the 180° / Vertical mode is selected, the upper half of the

screen shows a 180 bow-up presentation, while the lower part

is used for a vertical slice presentation. In that way an echo can

simultaneously be presented in both horizontal and vertical

dimensions. The bearing of the vertical slice is indicated in the

horizontal plane by the white audio line, and can be trained to

any bearing by the manual training knob. The white audio line

indicates the fore part of the 180 degrees vertical slice, and is

always preset to the right in the vertical presentation, while the

rear part is to the left. All of the vertical settings as range, gain

etc. may be selected separately in the Vertical menu.

If the vertical range is selected to be shorter than the sonar

range, it can be presented in the horizontal sonar picture with a

white circle selected in the Cosmetics menu. In addition to the

normal tilt indicator, the tilt angle is also shown in the vertical

slice by a continuous white line. In that way, it is easy to select

the optimal tilt angle on an echo in the vertical slice, to get the

best drawing of the echo in the horizontal presentation.
