Furuno 455T-SS903 Side-Scan Thru-Hull Stainless f/TZtouchXL Series

Discover the power of high-resolution underwater mapping with the Furuno 455T-SS903, a robust thru-hull transducer designed specifically for marine enthusiasts who demand precision on the water. This stainless steel powerhouse integrates seamlessly with your NavNet TZtouchXL series displays, transforming your multifunction display into a side-scan sonar wizard capable of revealing hidden structures, wrecks, and fish-holding hotspots with stunning clarity.

Experience Unmatched Side-Scan Performance

Side-scan sonar revolutionizes how you explore beneath the surface. Unlike traditional down-facing transducers, the 455T-SS903 casts wide, detailed beams to each side of your vessel, painting a comprehensive picture of the seafloor up to impressive ranges. Operating on CHIRP technology in the 445-465 kHz range, it delivers sharp images even in murky waters or over complex bottom terrain. Boaters often rave about its ability to pinpoint lost anchors, map drop-offs, or scout prime fishing grounds without guesswork.

With 150 watts of power per side, this transducer punches through sediment and provides reliable returns in varying conditions—from calm bays to moderate swells. The built-in temperature sensor adds another layer of utility, helping you correlate water temp changes with baitfish movements for smarter angling strategies.

Engineered for Durability and Reliability

Crafted from marine-grade stainless steel, the 455T-SS903 thru-hull design withstands the harsh marine environment, resisting corrosion and biofouling far better than plastic alternatives. Its streamlined housing minimizes drag, ensuring it won't compromise your boat's performance. The included 12-meter (40-foot) cable with a 12-pin connector simplifies routing through tight bilge spaces, while the secure connection guarantees uninterrupted data flow to your TZtouchXL MFD.

Effortless Integration with TZtouchXL Displays

Plug-and-play compatibility is a hallmark here. Pair it effortlessly with TZT10X, TZT13X, or TZT16X models to activate the built-in CHIRP side-scan features. No extra black boxes or modules needed—your display handles the processing, overlaying side-scan data directly on charts for intuitive navigation and fishing overlays. This setup shines during structure fishing, where combining side-scan with traditional sonar views uncovers details that forward-facing units might miss.

Installation Insights for Optimal Results

Thru-hull mounting places the transducer at the ideal depth for side-scan coverage, flush with or slightly below the hull for bubble-free operation. Position it forward of props and rudders to avoid interference, ideally amidships on deadrise angles up to 20 degrees. Use a fairing block on steeper hulls to align it perfectly horizontal—proper deadrise matching is key to maximizing beam coverage and image quality. Seal with marine sealant, and you're scanning in minutes. Pro tip: Test in shallow water post-install to fine-tune gain and range settings on your TZtouchXL for tailored performance.

Real-World Applications That Deliver Value

Fishermen use it to scan vast areas quickly, spotting submerged timber or rock piles where trophy fish lurk. Divers and surveyors appreciate its detail for reef mapping or hull inspections. Search-and-recovery teams rely on its resolution for locating small objects in deep water. Whether you're chasing stripers along coastal ledges or exploring inland lakes, this transducer elevates your situational awareness, saving time and boosting success rates on every outing.

Care and Maintenance for Long-Term Excellence

To keep your 455T-SS903 performing like new, inspect the face annually for growth and clean gently with a soft brush and non-abrasive cleaner. Avoid high-pressure washes near the cable entry. In saltwater, fresh rinses prevent salt buildup. Stored properly during off-seasons, it delivers years of trouble-free service, making it a smart investment for serious mariners.
