With up to 2,000 watts of transmit power and a high-dynamic-range receiver, the GSD 24 brings high-definition imaging, with amazing target separation and bottom tracking, to your compatible Garmin chartplotter.

Simple installation to the Garmin Marine Network’s high-speed connections ensure that you also get ultra-fast screen updates with minimal delay. GSD 24 is dual frequency (50/200 kHz) capable with pinpoint accuracy at depths of up to 5,000'. 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.
