Furuno 556TID-HDD SS260 Stainless Steel Thru-Hull Transducer w/Temp and Fairing Block - 10 Pin

The Furuno 556TID-HDD SS260 Stainless Steel Thru-Hull Transducer with Temperature and Fairing Block is purpose-built for serious anglers and boaters who demand reliable sonar performance across demanding saltwater and freshwater environments. This 10-pin transducer assembly integrates a temperature sensor alongside dual-frequency acoustic elements, making it the ideal choice for 1 kW echosounders that require both shallow-water target definition and deep-water penetration. Whether you're running structure in coastal estuaries, probing offshore depths, or searching bottom composition on inland reservoirs, this transducer delivers the data clarity needed to locate fish consistently.

The SS260 features separate 50 kHz and 200 kHz transducer elements housed in 316-grade stainless steel, a material selection that resists corrosion and extends service life in saltwater applications where galvanic degradation is a constant concern. The dual-frequency design allows operators to switch between narrow high-frequency beams for precision target identification and wider low-frequency coverage for bottom mapping and fish-finding in deeper columns. The integrated temperature sensor provides water-column data essential for interpreting fish behavior and thermocline location. The included fairing block streamlines water flow around the thru-hull housing, reducing cavitation noise and improving signal integrity during high-speed operation.

This transducer is best suited for anglers operating larger center consoles, sportfishing boats, and commercial vessels where installation space and 1 kW sonar system compatibility are established. The 10-pin connector ensures straightforward integration with compatible Furuno chartplotter and fishfinder displays. Installation requires a proper thru-hull mounting location with adequate water exposure; most professionals recommend placement at the boat's running surface, slightly aft of amidships, to minimize turbulence and vibration. The 22.15 lbs weight and robust stainless construction demand secure backing plate support to handle dynamic water loads and operational stress over years of intensive use.
