The GSD 24 features a vastly improved digital sonar design for superior target definition and deep-water performance.

Get the Whole Picture

With up to 2,000 Watts of transmit power and a high-dynamic range receiver, the GSD 24 brings high-definition imaging to your compatible Garmin chartplotter. The system is dual frequency (50/200 kHz) capable and offers selectable transmit power (600 W, 1 kW and 2 kW, depending on transducer) for pin-point accuracy at depths of up to 5,000 ft (1,500 m). So whether you’re out sportfishing or just keeping an eye on hazardous terrain and reef structures beneath your boat, you’ll see a clearer picture with enhanced separation of images and deeper bottom detection.

Plug and Play

Thanks to the easy connectivity of the Garmin Marine Network, installation of the GSD 24 is a snap. Once connected, your sonar data will be shared on any compatible chartplotter on the network. Plus, the network’s high-speed connections ensure that you get ultra-fast screen updates with minimal delay.
