Garmin GSD 28 Sonar Module | 010-02797-00

THE DEPTHS. REVEALED.
See what’s down there. Catch what’s down there. Take your sport fishing to extreme depths with a high-powered sonar module with the features you need to improve your chances for success.

GARMIN RAPIDRETURN SONAR
This high-performance technology provides our fastest deep-water scrolling sonar with 2 to 6 times the ping rate1 of our GSD™ 26 sonar. This allows captains to make fast and informed decisions based on what is below their boats.

XCHIRP TECHNOLOGY
Easily distinguish bait from sport fish with our clearest traditional sonar fish arches and excellent target separation. Get smooth bottom returns and precise targeting at extreme depths1.

HEAVE COMPENSATION
When the seas get rough, use the MSC™ 10 external satellite compass (sold separately) to greatly reduce wave and swell from your sonar returns.

TRANSDUCER SUPPORT
This sonar module is compatible with a wide range of Garmin and AIRMAR® transducers (sold separately).

The GSD 28 module is ideal for retrofitting to boats with existing bare wire transducers.
