Recording StructureScan data
StructureScan data can be recorded from a chart panel with Structure overlay enabled.
StructureScan recordings can also be started from a StructureScan panel. Refer to the NSS
Operation manual for more details.
When StructureScan data is being recorded, there
will be a flashing red symbol and a message will
appear periodically at the bottom of the screen.
¼ Note: The message includes information about
file size. Keep the size of your sonar logs to 100MB or
less to allow for faster file conversion.
The sounder recording is stopped by re-selecting
the record function.
Converting StructureScan data to StructureMap format
A StructureScan log file (.sl2) is converted to StructureMap format (.smf ) after recording from
the recording dialog, or from the Files dialog.
You can create standard or high resolution files. High resolution .smf files capture more detail,
but take longer to convert and are larger than standard resolution files.
To save disc space it is recommended to remove the StructureScan (*.sl2) files after conversion.
Using StructureMap with mapping cards
StructureMap allows you to maintain full chart capability, and it can be used with embedded
cartography as well as Navionics, Insight and other third-party charting cards compatible with
the NSS systems.
When using StructureMap with mapping cards, copy the StructureMap (.smf ) files to the
unit’s internal memory. We recommend keeping copies of StructureMap files on external
Micro-SD cards.
