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

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.
