GSD™ 28 Advanced Sonar Module

See what’s down there. Catch what’s down there. Take sport fishing to extreme depths with a high-powered sonar module with the features that are needed to improve the chances of success.

Features:

  • Engineered for offshore sport fishing
  • See sonar faster with Garmin RapidReturn™ technology
  • Crisp and clear fish targets with Xchirp technology

Garmin RapidReturn Sonar

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

Easily distinguish bait from sport fish with Garmin's 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 the sonar returns.
