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. When conducting a side-by-side scan of an area, you will get a cleaner scan if you do not overlap history trails and you turn off auto ranging on the sidescan. Side-by-side scan Scanning tips • To get a picture of taller structure (a wreck, etc) - don't drive over it. Steer the boat so the structure will be on the left or right side of your boat. • Set your structure range to a significantly greater level (two-tothree times) than the water depth to ensure a complete scan and to maximize conversion accuracy. NOTE: Optimal speed for viewing or logging StructureMap data is between 2-8 mph (3-12 kmh). Live mode is disabled for speeds greater than 10 mph. 20
