Bow up/Audio

When Bow up/Audio mode is selected, the upper half of the
screen shows a bow-up presentation, while the lower part is
used for a recording of the audio channel. The audio channel is
shown with a continuous white line in the horizontal picture,
and it can be trained in any direction. The recorded echoes are
a direct replica of the echoes under the white audio line. As
the audio channel is recorded over a period of time, this mode
is especially useful for detection of weak echoes mixed with
reverberation or noise. The information recorded by the audio
channel is always stored in the computer, even if another mode is
selected. That means that this recording will always be presented
when selecting the Bow up/Audio mode. Note that the vessel
symbol can be moved to any position in the horizontal view with
the cursor and
