Operation Manual

Log in XTF format
Optional logging format for SideScan data. This will only be shown when StructureScan data
is available.
This format does not log all channesl into onen file. The format is used for third part
application support on PC (like SonarWiz) that needs access to the StructureScan data.
Create StructureMap when completed
If StructureScan is available on the network, you can convert the loggings to StructureMap
format (.smf) after recording. The file can also be converted to StructureMap format from the
Files option.
Viewing the recorded sounder data
Both internally and externally stored sounder records may be reviewed when selected.
The log file is displayed as a paused image, and you control the scrolling and display from the
replay menu.
You can use the cursor on the replay image, and pan the image by tapping and dragging on
the screen as on a normal echo image.
If more than one channel was recorded in the selected echo file, you can select which
channel to display.
You exit the replay mode by pressing the X key or the symbol in the upper right corner.

Split screen options
Zoom
The Zoom mode presents a magnified view of the sounder image on the left side of the
panel.
By default the zoom level is set to 2x. You can select up to 8x zoom from the drop-down
menu.
The range zoom bars on the right side of the display shows the range that is magnified. If you
increase the zooming factor the range will be reduced. You will see this as reduced distance
between the zoom bars.
Bottom lock
The bottom lock mode is useful when you want to view echoes close to the bottom.
In this mode the left side of the panel shows an image where the bottom is flattened. The
range scale is changed to measure from the seabed (0) and upwards. The bottom and the
zero line will always be shown on the left image, independent on range scale.
The scaling factor for the image on the left side of the panel is adjusted as described for the
Zoom option.
Palettes
Enter a short description of your concept here (optional).
You can select between several display palettes optimized for a variety of fishing conditions.
Temperature graph
Enter a short description of your concept here (optional).
The temperature graph is used to illustrate changes in water temperature.
When toggled on a colored line and temperature digits are shown on the echosounder
panel.
Depth line
Enter a short description of your concept here (optional).
A depth line can be added to the bottom surface to make it easier to distingish the bottom
from fish and structure.
