Garmin GSD28 Sonar Module
Model: 010-02797-00The depths. Revealed. Take your sport fishing to extreme depths with GSD™ 28, a high-powered sonar module with features to improve your chances for success (transducer-dependent). Garmin RapidReturn™ sonar provides quicker returns on your chartplotter with 2 to 6 times the ping rate of our GSD 26, so you see fish before you’re out of range (transducer-dependent). Easily distinguish bait from sport fish, and get our clearest sonar with next-generation xCHIRP technology. GSD 28 supports a wide range of Garmin and AIRMAR® transducers (sold separately) that can be manually or automatically configured. When the seas get rough, ensure flat bottom returns with the MSC™ 10 external heave compensation sensor (sold separately).
The GSD 28 module is ideal for retrofitting to boats with existing bare wire transducers.
