New StructureMap™ View With HDS® Gen2

Only available with Lowrance HDS® Gen2 models, the new StructureMap™ overlay feature allows anglers and boaters to view and create life-like underwater images of the lake, river or seafloor.

With HDS® Gen2 networked to the optional StructureScan® sonar imaging module, you can easily overlay StructureScan® images on top of traditional charts to provide a real-time view into underwater structure and its precise location on the map.

View And Create Underwater Charts You can also create StructureMap™ images right on your boat or scan an area to create a detailed map for viewing off the water.

Choose Your Favorite HDS® Gen2 Mapping Option The new StructureMap™ feature works with the Lowrance enhanced basemap, built-in Insight cartography, Insight HD cards, Navionics® world background map, as well as Navionics® Gold, HotMaps® Premium and Platinum+ charts.

TrackBack And Never Miss A Key Hotspot You can also use the TrackBack™ feature on the HDS® Gen2 StructureMap™ overlay to review recorded sonar history, mark waypoints and save the location of important areas – structure, gamefish, baitfish, diving spots -- all without losing valuable sonar readings because HDS® Gen2 keeps recording while you’re marking those favorite locations.
