Description

The Garmin GSD 28 Sonar Module is a cutting-edge marine device engineered to elevate your fishing experience. With its advanced sonar capabilities, this module provides unparalleled clarity and detail of underwater structures and fish targets.


GARMIN RAPIDRETURN SONAR

This high-performance technology provides our fastest deep-water scrolling sonar with 2 to 6 times the ping rate1 of our older 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 depths.


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).


SONAR POWER

GSD 28 can output from 300 watts to 3 kW at extreme depths.


CHIRP SUPPORT

OPERATION RANGE

The GSD 28 sonar module can operate in the 25 to 250 kHz frequency range.


BUILT TO LAST
