Investigating The Bottom Characteristics - Simrad ES80 Reference Manual

Simrad ES80 Reference Manual
5 Investigate the information provided by the information pane.
This is basically the same view as in the Fish Position information pane. However,
the fish echoes are here viewed from the side and not from above. This means that
you can also investigate the depth of the single fishes in the beam.
The information in the Echo Position information pane is presented in 3D.
• On a standard computer mouse, use the middle wheel to zoom in and out.
• Right-click while moving the mouse pointer to alter the 3D presentation.

Investigating the bottom characteristics

The Bottom Hardness information pane shows you the current bottom reflectivity. This
gives an indication to how hard the bottom is. The value is calculated using the bottom
echo strength in the current ping.
Context
The bottom hardness shown in the information pane was detected by the latest ping in
the selected view.
When you study the bottom hardness, you can learn more about the bottom. Certain
species are known to prefer specific bottom conditions. With more knowledge, you are
better qualified to estimate the possible catch.
Tip
The Hardness Line can be added to your echogram to retrieve additional information. It
appears as thick colour coded line that follows the bottom contour. This line does not
remove information, it simply "pushes" the echo information further down in order to
show you the bottom reflectivity.
Procedure
1 Click in any echogram view to make it "active".
The setting you choose will only be valid for the currently "active" echogram. The
"active" echogram view is identified with a thicker border.
2 On the top bar, select the appropriate button to open the information pane.
3 Click the bottom right corner of the information pane, and drag to requested size.
