Hardness line
Figure 18 Hardness line
example
The bottom reflectivity (how “hard” it is) may be
monitored using the
Hardness
line.
The
Hardness
line is an extra thick colour coded line
that is added to just below the bottom. The line will not
remove information, it will simply “push” the information
further down in order to make the bottom easier to see.
The colour coding contains the hardness information.
You may find it useful to open the
Bottom Hardness
information pane to observe the scale. 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 information pane also provides the current reflectivity
measured in dB.
Please note that bottom hardness is an optional function. In order to activate the
Hardness
line and the
Bottom Hardness
information pane, you must obtain a licence.
The
Hardness
line can not be used simultaneously with the white line.
The
Hardness
line is enabled in the
Echogram
dialog.

Trawl line
Whenever available and connected, trawl systems (PI and ITI) communicate headrope
depth and/or headrope-to-footrope distance to the ES70 at regular intervals. The
information from these sensors are drawn as horizontal lines on the ES70 echogram.
The trawl line is enabled in the
Echogram
dialog on the
Active
menu.
