Overview

Garmin GSD™ 28 Sonar Module: Advanced Marine Sonar Technology

Step into the next generation of marine sonar exploration with the Garmin GSD™ 28 Sonar Module. Designed for unparalleled underwater imaging, this state-of-the-art sonar system offers high-resolution visuals, customizable settings, and cutting-edge technology to enhance your fishing and marine adventures.

Unmatched Performance and Innovation

RapidReturn™ Sonar – Processes up to 6 times the ping frequency of the previous GSD 26, delivering real-time underwater data for quick and informed fishing decisions. This technology ensures you detect fish before they move out of range, increasing your chances of a successful catch.
Next-Gen xCHIRP Technology – Provides the clearest sonar signals yet, offering exceptional target separation, precise bottom returns, and the ability to distinguish between bait and larger sport fish, even at depths of up to 10,000 feet.
High-Power Output – With an adjustable power range from 300W to 3kW, the GSD 28 is built for deep-water fishing. When paired with the MSC™ 10 external satellite compass (sold separately), it compensates for wave and swell movements, ensuring precise sonar readings even in rough waters.

Customizable and Versatile Sonar Solution

Broad Transducer Compatibility – Works with a variety of Garmin and AIRMAR® transducers, allowing you to tailor your sonar setup to different fishing environments. Whether in shallow or deep waters, you can select the ideal transducer for optimal sonar performance.
Dual-Channel CHIRP Technology – Operates across a 25-250 kHz frequency range, depending on the transducer in use, ensuring exceptional depth penetration and detail clarity.
Rugged and Durable Design – Built to withstand harsh marine conditions, the GSD 28 is IPX7-rated for water resistance, ensuring reliability and longevity in demanding environments.

Installation and Compatibility

The GSD 28 is an excellent choice for both new installations and retrofitting to boats with existing bare-wire transducers. It includes mounting hardware, a power cable, a Garmin BlueNet™ marine network cable (1.8m/6ft) with a legacy adapter, and a field-installable adapter kit.
