Upgrade your marine electronics setup with the Furuno 556TID-LTD/12, a rugged stainless steel thru-hull transducer designed for boaters who demand reliable sonar performance in challenging conditions. This 1kW powerhouse features a 12-degree tilted element that perfectly matches hull deadrises between 8° and 15°, ensuring crystal-clear bottom tracking and fish detection without the guesswork of misalignment.

Engineered for Precision and Depth

Crafted with an Airmar SS164 housing style, this transducer delivers dual-frequency operation at 50/200 kHz, giving you versatility for everything from shallow coastal cruising to deep offshore adventures. The wide 20° beam at 50 kHz excels at scanning large areas for structure and bait schools, while the narrow 6° beam at 200 kHz provides pinpoint detail for marking individual fish or navigating wrecks.

• Power Output: 1kW for superior signal penetration in deeper waters.
• Integrated Temperature Sensor: Monitor water temps in real-time to track thermoclines and fish behavior.
• Beam Angles: 20° at 50 kHz / 6° at 200 kHz for balanced coverage and resolution.
• Cable: 30-foot length with a 10-pin connector for straightforward integration.

Seamless Adaptation to Your Hull

Boat hulls aren't flat, and this transducer gets that. The built-in 12° tilt compensates for your deadrise angle, directing sound waves straight down toward the bottom rather than at an awkward angle. Look for the arrow on the housing top—it points toward the keel for foolproof orientation, whether mounting port or starboard. This simple alignment hack minimizes distortion and maximizes your fishfinder's potential.

Built to Withstand the Marine Environment

Stainless steel construction laughs off corrosion, impacts from debris, and the constant pounding of waves. Unlike plastic alternatives, it holds up in saltwater without degrading, making it a smart long-term investment for serious anglers and commercial operators alike. Fairing blocks can enhance performance further by streamlining water flow over the housing.

Installation Insights for Peak Results

Mounting a thru-hull like the 556TID-LTD/12 offers advantages over transom or in-hull options: cleaner signals, less interference, and better speed tolerance. Drill a precise hole sized to the housing, bed it in marine sealant, and secure with the nut—avoid over-tightening to prevent cracking. Position it forward of props and strakes for optimal water flow. Test in shallow water post-install to verify readings.

Why Boaters Trust This Setup

Whether you're chasing trophy tuna in deep blue or bass nearshore, the combination of high power, dual beams, and tilt compensation delivers actionable intel. Pair it with modern Furuno displays for CHIRP-enhanced imaging, revealing bait balls and bottom contours with stunning clarity. Skip the frustration of dead zones or fuzzy returns— this transducer keeps you locked on target.
