Marine Sounder & Sonar Modules
Enhance your vessel’s sonar capabilities with professional-grade marine sounder and sonar modules. These external sonar processors expand the performance of compatible GPS chartplotters and multifunction displays, delivering advanced CHIRP sonar, side imaging, down imaging, and deep-water scanning capabilities.
What Is a Sonar Module?
A sonar module is an external processing unit that connects to a GPS Chartplotter or multifunction display to improve fishfinding accuracy and depth performance. When paired with high-performance Marine Transducers, sonar modules provide superior target separation and bottom structure clarity.
Why Add a Sounder Module?
- Upgrade to high-power CHIRP sonar
- Improve deep-water depth tracking
- Expand side & down imaging capabilities
- Increase fish target separation
- Enhance offshore fishing performance
System Integration & Networking
Most sonar modules integrate through marine Ethernet or NMEA 2000 networks. Expand your setup using Network Cables & Modules for seamless onboard communication.
