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.
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.
When the seas get rough, use the MSC™ 10 external satellite compass (sold separately) to greatly reduce wave and swell from your sonar returns.
SONAR POWER: GSD 28 can output 300 watts to 3 kW at extreme depths1.
CHIRP SUPPORT: The module supports dual-channel CHIRP (up to 3 kW per channel).
OPERATION RANGE: The GSD 28 sonar module can operate in the 25 to 250 kHz frequency range1.
