Live data
When live data is selected, the SideScan imaging history is displayed
as a trail behind the vessel icon. The length of this trail varies
depending on available memory in the unit and range settings. As
the memory fills up, the oldest data is automatically deleted as new
data is added. When increasing the search range, the ping speed of
the SideScan transducer is reduced, but the width and the length of
the image history is increased.
Ú
Note:
Live mode does not save any data. If the unit is turned off,
all recent data is lost.
Saved files
Saved mode is used to review and examine StructureMap files, and
to position the vessel on specific points of interest on a previous
scanned area. Saved files can be used as source if no SideScan
sources are available.
With this mode selected, the StructureMap file is overlaid on the
map based on position information in the file.
If the chart scale is large, the StructureMap area is indicated with a
boundary box until the scale is large enough to show Structure
details.
Ú
Note:
When saved files are used as the source, all StructureMap
files found on the storage device and in the system’s internal
memory are displayed. If there is more than one StructureMap
of the same area, the images overlap and clutter the chart. If
several logs of the same area are required, the maps should be
put on separate storage devices.
StructureMap tips
•
To get a picture of taller structures (a wreck, etc.) — do not drive
over it, instead, steer the boat so the structure is on the left or
right side of your vessel.
•
Do not overlap history trails when conducting a side-by-side scan
of an area.
