Furuno Thru-Hull Side-Scan Transducer 12-Pin f/TZtouch3 12, 16 & 19 Models

Unlock Crystal-Clear Underwater Views with the Furuno 225T-SS904

Imagine gliding across the water, effortlessly spotting hidden reefs, sunken wrecks, or schools of fish lurking just beyond your boat's path. The Furuno 225T-SS904 thru-hull side-scan transducer brings this vision to life, seamlessly integrating with your NavNet TZtouch3 TZT12F, TZT16F, or TZT19F multifunction display. Unlike traditional down-facing sonar, this powerhouse delivers high-resolution images from both sides of your vessel, helping anglers and navigators make smarter decisions on the water.

Crafted for serious boaters who demand precision and durability, the 225T-SS904 combines CHIRP technology in the 220-240 kHz range with 150 watts of power per side. This setup cuts through murky waters to reveal fine details, from baitfish balls to bottom contours, enhancing your overall situational awareness during fishing trips or coastal explorations.

Key Advantages for Everyday Boating Adventures

• Superior Side-Scan Coverage: Each side beams out 150 watts, painting a wide swath of the seafloor up to impressive ranges, perfect for scouting large areas quickly.
• Rugged Stainless Steel Construction: Built to withstand harsh marine environments, this thru-hull mount includes a built-in temperature sensor for real-time water data, correlating thermal layers with fish activity.
• Plug-and-Play Simplicity: The 12-pin connector mates directly to your TZtouch3 system, with a generous 40-foot cable offering flexible routing through tight bilge spaces.
• Enhanced CHIRP Performance: The 220-240 kHz frequency excels in shallow to mid-depth waters common to bays, rivers, and inshore fishing grounds, minimizing interference and maximizing clarity.

Whether you're chasing trophy bass in freshwater lakes or mapping structure for offshore charters, this transducer elevates your electronics setup without the complexity of add-on modules.

Seamless Installation and Compatibility Tips

Installing the Furuno 225T-SS904 is straightforward for DIY enthusiasts or pros alike. Select a smooth hull section below the waterline, away from strakes or thru-hulls that could disrupt the beam. Drill precisely, bed with marine sealant, and secure the stainless steel housing—most installs take under an hour. Pair it with your TZtouch3's native side-scan processing for instant overlays on charts and sonar screens.

Pro tip: Fair the transducer face flush with the hull to optimize beam patterns, and always deadrise-match for multihull vessels. Its temperature probe feeds valuable data to your MFD, aiding in finding those prime fishing spots where water temps attract gamefish.

Real-World Performance That Outshines the Competition

Boaters rave about how the 225T-SS904 transforms vague sonar returns into vivid, photo-like images. In choppy conditions, its focused CHIRP pulses maintain target separation, spotting individual fish amid vegetation or debris. For wreck divers or surveyors, the dual-side scanning reveals anomalies missed by forward-facing units, saving time and fuel on searches.

Backed by Furuno's reputation for reliability, it pairs perfectly with the TZtouch3 ecosystem, unlocking features like automatic gain control and bottom discrimination right out of the box.

Maintenance for Long-Lasting Results

Keep your 225T-SS904 performing at peak by rinsing with fresh water after saltwater exposure and inspecting the cable for chafe during haul-outs. Avoid antifouling paints on the active face to preserve acoustic transparency. With proper care, expect years of trouble-free service, complementing the included warranty.
