180°/Audio

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

screen shows a 180 degrees 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

180°/Audio mode. Note that the vessel symbol can be moved to

any position in the horizontal view with the cursor and Off

Centre button.
