FeaturesThis is the latest and greatest evolution of sportfishing technology. The GSD 26 is unmatched in target separation, which you get at far greater depths than traditional sonar. Essentially, the GSD 26 is serious sonar for serious sportfishing.
See everything If you’re an avid sportfisherman, you want the GSD 26 by your side. With a compatible transducer, the Spread Spectrum technology simultaneously scans multiple frequencies, giving you an incredible level of data. So when you’re deep sea fishing up to 10,000 feet (3,000 meters), you’ll still get precise target separation as if you were in shallow water.
With the GSD 26, you’ll enjoy enhanced targeting of specific fish with the manually adjustable frequencies from 25 kHz to 210 kHz. And, for even more control over your sonar returns, you can adjust transmit power from 300 W to 3 kW.
Two in one The GSD 26 is almost like two sonars in one great package. Its dual transceiver allows for simultaneous and independent transducer operation. You can control all the data you see on your compatible Garmin Chartplotter, which you can easy connect with your GSD 26 using the Garmin Marine Network.
