overlap and clutter the chart. If several logs of the same area are required, the maps should be put on separate microSD cards. 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 boat. • Do not use Autorange when using StructureScan. Set your structure range to a significantly greater level (two-to-three times) than the water depth to ensure a complete scan and to maximize conversion accuracy. • Do not overlap history trails when conducting a side-by-side scan of an area. 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. When StructureScan data is being recorded, there is a flashing red symbol and a message appears periodically at the bottom of the screen. Ú Note: The message includes information about file size. Keep the size of your logs to 100MB or less to allow for faster file conversion. The 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 browser. 88 StructureMap | HDS Gen3 Operator Manual

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 boat.
•
Do not use Autorange when using StructureScan. Set your
structure range to a significantly greater level (two-to-three
times) than the water depth to ensure a complete scan and to
maximize conversion accuracy.
•
Do not overlap history trails when conducting a side-by-side
scan of an area.
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.

screen.
Ú
Note:
The message includes information about file size.
Keep the size of your logs to 100MB or less to allow for
faster file conversion.
The recording is stopped by re-selecting the record function.
