The Lowrance S3100 High-Performance Sonar Module is an advanced sonar module that supports the new high-resolution Active ImagingHD sonar and is compatible with HDS LIVE, HDS Carbon, and Elite FS displays. The S3100 delivers crystal clear and detailed images of both fish and underwater structures thanks to its high frequency SideScan and DownScan Imaging, with frequencies reaching up to 1 Megahertz. This makes it easier to identify and find fish at greater distances and with greater precision than ever before. The module has two 9-pin connectors, one blue and one black, which provides greater flexibility and the ability to connect multiple transducers to optimize your fishing experience. One of the most prominent features is the new FishRevealSideScan view, which combines the detailed rendering of SideScan with the excellent sharpness and target separation of Lowrance CHIRP sonar. This means you no longer have to guess where the fish is, as you can see it clearly from both sides
