Humminbird XNT-9-28-T Transom Mount Transducer

Imagine gliding across the water, your Humminbird fishfinder lighting up the screen with sharp, detailed images of fish, structure, and the lake bottom below. The XNT-9-28-T transom mount transducer makes that vision a reality, delivering reliable performance whether you're chasing walleye in shallow bays or scanning deeper offshore waters. Built tough for everyday anglers who demand precision without the fuss, this dual-beam powerhouse combines wide coverage for spotting schools with narrow focus for pinpoint accuracy.

Superior Dual-Beam Technology for Every Fishing Scenario

At the heart of the XNT-9-28-T lies its versatile dual-beam setup: a wide 28-degree beam at 200 kHz for broad-area searches, perfect for covering large swaths of water and quickly locating baitfish or pods of gamefish. Switch to the narrower 16-degree beam at 455 kHz for high-definition details on wrecks, drop-offs, and individual fish—ideal for those nail-biting moments when you need to differentiate a trophy from a dink. The integrated temperature sensor adds another layer, tracking water temp changes that signal feeding frenzies or migrations, helping you stay one step ahead of the fish.

• Wide beam excels in open water, revealing fish up to 300+ feet in ideal conditions.
• High-frequency narrow beam shines in shallows (under 50 feet), cutting through clutter for clean bottom separation.
• Temp probe ensures you're dialed into thermoclines where big fish hang out.

Rugged Build That Handles Real Boating Abuse

Transom mounting keeps this transducer streamlined along your boat's hull, minimizing drag while capturing uninterrupted sonar returns at speed or on the troll. The innovative impact-release bracket is a game-changer— it pivots upward if you clip a log or stump, protecting both the unit and your gear from damage. With a generous 20-foot cable, routing to your display is straightforward, even on larger consoles. Anglers rave about its durability in choppy conditions, from Great Lakes waves to bass tournament trails, proving it's not just reliable but battle-tested.

Effortless Setup Tailored for DIY Enthusiasts

Mounting the XNT-9-28-T is straightforward with basic tools and a bit of planning. Start by selecting a spot 1/3 from the transom's center to the corner, ensuring a clean water flow path. Drill pilot holes, secure the bracket with stainless hardware, and adjust the running angle for optimal hull contact—typically parallel to the waterline at planing speeds. Grease the transducer face to prevent air pockets, zip-tie the cable securely along the hull, and route it inside away from electrical noise. Test at idle and wide-open throttle to fine-tune; most setups take under an hour and lock in performance for seasons.

1. Clean and sand the transom surface for a solid bond.
2. Position for maximum transducer submersion without ventilation.
3. Use the optional lock-down screw for high-speed runs or rocky shallows.
4. Double-check cable strain relief to avoid chafing.

Pro tip: Pair it with foam flotation under the bracket for extra kick-up insurance in skinny water.

Broad Compatibility Across Humminbird Lineup

This transducer syncs seamlessly with a wide array of Humminbird models, from compact PiranhaMAX units for kayak fishing to feature-packed Helix and Solix series for serious offshore adventures. It's a plug-and-play upgrade for older 300/400/500 Series combos too, breathing new life into your setup without compatibility headaches. Whether you're running 2D sonar, adding Down Imaging potential, or just want better target separation, the XNT-9-28-T slots right in.

Maximize Performance with Smart Angler Tips

In practice, shine brightest in 5-100 foot depths where the dual frequencies overlap for hybrid views—spot suspended crappie with the wide beam, then zoom in with 455 kHz for precise jigging depths. Trolling for stripers? The temp sensor flags ideal speeds (2-4 mph) tied to surface readings. Maintenance is simple: rinse after saltwater trips, inspect the face for nicks, and store dry. Users report years of crisp sonar without recalibration, making it a smart investment for tournament pros and weekend warriors alike.
