Sonar Modules

The Leader In Sonar Performance

Since 1957, Lowrance has led the way to provide anglers of all skill levels with the best possible underwater view of fish and fish-holding structure. From the Fish Lo-K-Tor – also known as the “The Little Green Box” – to today’s powerful HDS Gen2 fishfinder/chartplotter models and StructureScan® HD, Lowrance’s commitment to produce award- and tournament-winning sonar technology continues today as a primary focus.

StructureScan 3D

StructureScan® 3D imaging scans underwater terrain and fish-holding structure to create a high-resolution, 180-degree, three-dimensional view beneath your boat.  With this unique imaging view, anglers gain a better understanding of where fish and structure are located in relation to their boat. StructureScan 3D is powered by a multi-beam sonar technology that not only produces picture-like, three-dimensional views of underwater structure and bottom contours, but also boosts the performance of two-dimensional Downscan and StructureScan HD imaging.


SonarHub™ Sounder Module

The compact SonarHub™ Sounder Module provides an all-in-one solution for adding best-in-class StructureScan® HD and single-channel CHIRP sonar capabilities to compatible Lowrance fishfinder/chartplotter displays.

SpotlightScan™ Sonar

SpotlightScan™ Sonar trolling-motor transducer delivers a new level of angler-controlled, surround-scanning views to provide picture-like images of key fishing areas on your HDS Gen2* or HDS Gen2 Touch fishfinder/chartplotter display. Similar to the way a scanning spotlight reveals objects in the dark, SpotlightScan™ Sonar clearly pinpoints structure and fish targets ahead and around the boat, so anglers save valuable time on the water and maintain focus on the most productive fishing spots – all without disturbing these areas before you have a chance to fish them.
