Show backscatter is used to display the backscatter/
hardness information.
The backscatter information can be displayed in grey-scale
or colour-scale. See “Hardness Tab” on page 20 for
configuration.
Changes in hardness will be drawn as different intensity/
colour.
This mode is very useful for finding the changes in seafloor
even when the seafloor is very flat. This gives the user a
good indication of where the rocky/hard areas and the soft/
muddy areas are.

Show 2D Fish will overlay the detected water column marks
on the 2D display.
These marks are coloured by intensity, so red marks are
strong echoes and blue marks are weak echoes.
To get the best from the water column data, the WASSP
GUI fish overlay settings should be correctly set. It is
recommended that the
Fish Threshold
in WASSP is set to
at least 4 depending on how noisy the sonar display is. See
“Fish Options” on page 16 for more information.
