The depths. Revealed. Take your sport fishing to extreme depths with GSDTM 28, a high-powered sonar module with features to improve your chances for success (transducer-dependent). Garmin RapidReturnTM 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(R) transducers (sold separately) that can be manually or automatically configured. When the seas get rough, ensure flat bottom returns with the MSCTM 10 external heave compensation sensor (sold separately).
