Garmin GSD 28 Sonar Module
Description
The Garmin GSD 28 is a supercharged sonar module engineered specifically for serious offshore sport fishing, delivering extreme deep-water performance down to 10,000 feet. Powered by Garmin RapidReturn technology, it provides 2 to 6 times the ping rate of the GSD 26, giving captains faster, more actionable information about what lies beneath the hull. xCHIRP technology produces razor-sharp fish arches and outstanding target separation, so you can confidently distinguish bait from trophy sport fish even at extreme depths.
Built for the harshest marine environments with an IPX7 water-resistance rating and a rugged aluminum housing, the GSD 28 is designed to perform when the conditions are anything but ideal. Heave compensation - when paired with the MSC 10 satellite compass (sold separately) - greatly reduces wave and swell interference from bottom returns, keeping your picture clean in rough seas. Compatible with a wide range of Garmin and AIRMAR transducers, the GSD 28 is also an ideal retrofit solution for boats already fitted with bare wire transducers.
Key Features
- Garmin RapidReturn Technology: Delivers 2 to 6 times the ping rate of the GSD 26 for the fastest deep-water sonar scrolling available from Garmin.
- xCHIRP Technology: Produces crisp, clear fish arches and excellent target separation - easily distinguish baitfish from sport fish at extreme depths.
- Maximum Depth - 10,000 ft (3,048 m): Engineered for extreme offshore depths, giving serious anglers access to the deepest fishing grounds.
- Dual-Channel CHIRP - Up to 3 kW per Channel: Supports dual-channel CHIRP sonar across the 33-250 kHz frequency range for flexible transducer compatibility.
- Transmit Power - 300W to 3 kW rms: High-power output ensures strong, reliable returns even at the most extreme depths (transducer dependent).
- Heave Compensation: Reduces wave and swell artifacts from bottom returns when used with the MSC 10 satellite compass (sold separately).
- IPX7 Water Resistance: Fully gasketed aluminum housing with steel back panel is rated for harsh marine environments.
- Broad Transducer Compatibility: Works with a wide range of Garmin and AIRMAR transducers (sold separately) and is ideal for retrofitting boats with existing bare wire transducers.
- Garmin BlueNet Networking: Includes one Garmin BlueNet marine network port plus a 6 ft BlueNet cable with legacy adapter for easy integration.
- Wide Compatible Device List: Integrates with GPSMAP 700, 900, 1000, 1200, 1600, 8400, 8600, and 9000 series chartplotters, as well as Volvo Penta Glass Cockpit System.

Why You'll Love It
The GSD 28 represents the pinnacle of Garmin's sonar technology for offshore fishing, trusted by tournament captains and serious anglers who demand performance at the deepest reaches of the ocean. RapidReturn technology means you're never waiting on your sonar - decisions happen faster, and fish don't get away. xCHIRP's target clarity means confidence at the helm, whether you're marking structure at 500 feet or chasing pelagics in 5,000 feet of water.
The rugged aluminum housing and IPX7 rating mean this module is built to outlast seasons of hard offshore use without missing a beat. Its broad compatibility with Garmin GPSMAP chartplotters and AIRMAR transducers makes it a versatile upgrade for new builds and retrofit installations alike. If you're serious about offshore sport fishing, the GSD 28 is the sonar module that will put more fish in the box.

FAQ
What transducers are compatible with the GSD 28?
The GSD 28 is compatible with a wide range of Garmin and AIRMAR transducers sold separately. It connects via 2 bare wire sonar connections and operates in the 33-250 kHz frequency range, supporting dual-channel CHIRP up to 3 kW per channel. Check Garmin's transducer compatibility guide or contact us if you need help selecting the right transducer for your application.
Does the GSD 28 work with my existing Garmin chartplotter?
The GSD 28 is compatible with a broad list of Garmin GPSMAP chartplotters including the 700, 900, 1000, 1200, 1600, 8400, 8600, and 9000 series, as well as the Volvo Penta Glass Cockpit System. It connects via the Garmin BlueNet marine network port (included cable). A legacy network adapter is also included for older-generation Garmin network setups.
What is heave compensation and do I need it?
Heave compensation reduces the noise and distortion in your sonar picture caused by wave and swell action - a common problem when fishing in rough offshore conditions. It requires the MSC 10 external satellite compass, which is sold separately. If you fish in consistently calm inshore waters it may not be critical, but for bluewater offshore anglers dealing with swells, it can significantly improve the readability of your sonar returns.
Can the GSD 28 be retrofitted to a boat that already has transducers installed?
Yes - the GSD 28 is specifically designed with retrofitting in mind. It connects to existing bare wire transducers directly through its 2 bare wire sonar connections, making it straightforward to upgrade a vessel that already has transducers in place without needing to re-run wiring through the hull.
How deep can the GSD 28 sonar reach?
The GSD 28 is rated for a maximum depth of 10,000 feet (3,048 meters), though actual performance depends on the transducer used and water conditions. With its 300W to 3 kW transmit power and dual-channel CHIRP support, it is engineered to deliver reliable returns at extreme offshore depths that most sonar systems simply can't reach.
