Furuno 555SLTD12 Stainless Steel 50/200KHZ 12DEG Tilt TH

The Furuno 555SLTD12 Stainless Steel 50/200KHZ 12DEG Tilt TH is a precision through-hull transducer engineered for anglers and boat operators who demand reliable sonar performance in variable hull geometries. This 600-watt tilted-element transducer accommodates deadrise angles between 8 and 15 degrees, making it ideal for moderate V-hull and semi-displacement boats where flush mounting is preferred. Built on decades of Furuno's marine electronics heritage, this transducer delivers the dual-frequency flexibility serious fishermen depend on for both shallow-water structure work and deep-water bottom tracking.

The 555SLTD12 operates across 50 kHz and 200 kHz frequencies, providing broad coverage for identifying baitfish, thermoclines, and hard structure at multiple depths and resolutions. The 12-degree tilt design compensates for hull deadrise, ensuring optimal transducer-to-water contact angle without performance loss—a critical factor that separates quality sonar returns from washed-out, unreliable imagery. Constructed from marine-grade stainless steel, the housing resists corrosion in saltwater environments and withstands years of operational demands. The unit weighs 5 pounds and integrates seamlessly with Furuno navigation and fishfinding systems, delivering consistent 600-watt pulse strength across both frequency bands.

This transducer suits cruising anglers, charter captains, and serious recreational boaters operating moderate-deadrise hulls who need flush-mounted sonar without compromise. Installation requires a properly sized through-hull fitting aligned to the hull's deadrise angle—the 12-degree tilt accommodation eliminates the guesswork and dead zones that plague improperly angled transducers. Verify your hull's deadrise angle before ordering; boats exceeding 15 degrees deadrise should instead use the 555SLTD20 variant. When properly installed and integrated with compatible Furuno chartplotters and fish finders, this transducer delivers the bottom definition and target separation that turns casual fishing trips into productive days on the water.
