Bottom Hardness information pane description

The Bottom Hardness information pane shows you the current bottom reflectivity. This
indicates what type of bottom you have under your keel. The value is calculated using
the bottom echo strength in the current ping.

activate it, then select the
information pane, select the button on the top bar one more time. You can also

Description
The bottom hardness shown in the information
pane was detected by the latest ping in the
selected view. The colours on the left side of the
scale indicate a soft bottom, while the colours
on the right hand side indicate a harder bottom.
The vertical line in the hardness colour scale
positions the latest ping. The current reflectivity
is also shown measured in dB.
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.
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.
