You can use Sidescan to: • Save waypoints at objects/locations off to side of the boat • Review history • easure the size of underwater objects and the distance from one M object/location to another object/location using live Sidescan returns or Sidescan history • Create sonar logs Downscan Uses the same technology as sidescan, but broadcasts the beam downward, giving you the same high resolution in a familiar right to left display.

StructureMap StructureMap is a tool that allows you to overlay SideScan sonar returns on top of the chart, giving you a birds-eye view of underwater structure below and beside your boat. StructureMap makes it easier for you to visualize the underwater environment in relation to your position and aids the user in interpreting sidescan sonar images.
Turning on Structure overlay Selecting Structure Source StructureMap can be used in Live mode or Saved mode. Live mode allows you to view real-time StructureMap data on the screen. Saved mode is used to display StructureMap data previously saved to a SD card or the unit’s internal memory. Live mode Displays the last few minutes of the Side Imaging history as a trail behind the vessel icon. The length of this trail will vary depending on the Side Imaging and Down Imaging range settings.
the history length that will show up behind the vessel icon. Typically it will display the last 4-5 minutes of recording. Live mode allows the user to quickly identify interesting areas of the lake and how they relate to vessel position. It also allows the user to scroll back and zoom in on a recently scanned areas of the lake to look at additional details of what was scanned. Live mode does not save any data. If the unit is turned off, all recent sonar history is lost.
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. NOTE: For best results, we recommend turning off Auto Range when recording a structure sonar log (.sl2).
Sharing files After structure sonar log (.sl2) files are converted to StructureMap (.smf ) files, they can be saved to a SD card and used on other GPS capable HDS Gen 2 units without the need for the StructureScan module. Scanning Fishing areas With the Structure Source set to the default Live mode, steer the boat over the desired location to scan the area.
Using StructureMaps with mapping cards StructureMap allows you to maintain full chart capability and can be used with embedded cartography as well as Navionics, Insight and other thirdparty charting cards compatible with HDS units. To view StructureMap data with other mapping card data on an HDS-8 or HDS-10, place the mapping card in one card slot and the SD card with the StructureMap file in the other slot. If you have an HDS-5 or HDS-7, copy the StructureMap (.
Accessing Structure Options Structure options: • Range — Adjusts the width of the sidescan history trail. The greater the range setting, the wider the StructureMap history trail; Lower range settings reduce the width of the history trail. • ransparency — Increases/decreases the visibility of Structure T overlay on top of the map. This is helpful when using marine mapping cards.
