Lowrance S3100 Sonar Module

The compact S3100 sonar module takes your fishing to the next level, with a wealth of powerful fishing features packed into one small but intelligent box. The S3100 brings Active Imaging™ HD to NSS™ and NSO™ Evo™3S displays. Experience superior underwater clarity and a FishReveal™ view on SideScan, so you’ll never miss another fish.

Active Imaging HD

The S3100 provides support for high-definition Active Imaging™ HD sonar to HDS LIVE, HDS Carbon and Elite FS displays. Active Imaging HD delivers the clearest images of fish and structure with Lowrance® CHIRP sonar and high-frequency (up to 1 Megahertz) SideScan and DownScan Imaging™ – plus FishReveal™ DownScan and SideScan views, making fish identification easier below and to the sides of the boat.

FishReveal™ SideScan View

Fish will be easy to see on both sides of the boat with the new FishReveal SideScan view, which takes the guesswork out of fish identification by combining on one screen the incredible detail of high-frequency SideScan with the superb clarity and target separation of Lowrance CHIRP sonar. Available for HDS PRO, HDS LIVE, HDS Carbon and Elite FS displays.

Track Multiple Depth Ranges

With two fully independent 1kW sonar channels, you can connect the S3100 to up to two additional transducers to track multiple depth ranges at the same time.
