Product Overview

The GSD 24 features a vastly improved traditional 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, with amazing target separation and bottom tracking, to your compatible Garmin chartplotter.

Dial in your transmit power: GSD 24’s transmit power is selectable—from 600W, 1kW or 2kW—with a wide choice of compatible 8-pin transducers. Simple installation to the Garmin Marine Network’s high-speed connections ensure that you also get ultra-fast screen updates with minimal delay.

Traditional dual frequency operation: 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.
