The easy-to-install, networkable GLS 10 sonar black box allows you to see live, real-time scanning sonar. Add the LVS32 transducer model to see easy-to-interpret live scanning sonar images of structure, bait and fish swimming below and around your boat. And you can share sonar images seamlessly across multiple networked chartplotters.
