Description

Take your sport fishing to extreme depths with the GSD 28, a high-powered sonar module with features to improve your chances for success down to 10,000’ (transducer-dependent). Garmin RapidReturn sonar provides quicker returns on your chartplotter with 2 to 6 times the ping rate of our industry-leading GSD 26 module, so you see fish before you’re out of range. Easily distinguish bait from sport fish, and get our clearest sonar with next-generation xCHIRP technology. The GSD 28 sonar module 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).
