Bow up/180° Vertical

When the Bow up/180° Vertical mode is selected, the upper part
of the screen shows a curtailed Bow up presentation, while the
lower part shows a 180 degrees Vertical slice presentation. This
mode is mainly intended for trawlers, where the vertical view
acts as a multibeam echo sounder. The bearing of the vertical
slice can be selected in the
the audio line, an indicator line, or you can set it to be locked
in forward, aft or athwart ships position. As the cylindrical
transducer has a "blind zone" straight down, an echo presentation
in this direction will be limited to two approximately 60 degrees
sectors. To avoid this "blind zone", the vertical slice is made
"tippable", and by selecting a -60 degrees tip angle (or less),
a full 180 degrees coverage is obtained. The tip angle can be
adjusted from +10 to -90 degrees. In addition to the read-out in
the menu button, the selected tip angle is shown with a dotted
Tip
yellow line in the tilt indicator in the upper left corner.
