Accessing StructureMap files on SD card 

All StructureMap files on your SD card or in the unit’s internal memory will 

automatically appear on the screen when Saved mode is selected. 

Recording Structure data

To record structure data, steer your boat 

over an area and select 

Log Sonar data 

from 

the Structure Options menu. Refer to your 

operation manual for more information about 

sonar log options.

Converting files

To create a StructureMap file you must convert a structure sonar log (.sl2) 

file to StructureMap format (.smf). This can be done automatically from 

the Sonar Log menu, or manually by converting logs from the Files menu.  

We recommend using an SD card for recording when possible, due to the 

limited size of the HDS internal memory.  To have structure sonar log (.sl2) 

files automatically converted to StructureMap file format (.smf), turn on 

Convert to map when complete

 on the Sonar Log menu. The (.sl2) file will be 

converted to a (.smf) file when recording is stopped. 

nOtE

For best results, we recommend turning off Auto Range when 

recording a structure sonar log (.sl2). 

Manual conversion

Automatic conversion

nOtE

Keep the size of your sonar logs to 100MB or less to allow for 

faster file conversion. Current file size is occasionally flashed on the 

screen during the recording process. You will not be able to use any of 

the unit’s other functions while a file is being converted.
