Know before you buy
No, this specific model is optimized exclusively for the Furuno DFF3D multibeam sonar system. It is not designed to provide the same performance or functionality with other Furuno sounder modules.
The integrated motion sensor compensates for the pitch and roll of your vessel. This ensures that your sonar display remains stable and accurate, even when you are navigating through choppy water or heavy swells.
Yes, bronze thru-hull transducers are susceptible to marine growth and corrosion. You should apply a high-quality, transducer-safe anti-fouling paint to the face of the unit to prevent buildup and ensure consistent sonar performance.
The wide 120° port-to-starboard coverage allows you to scan a much larger area of the seabed compared to traditional narrow-beam transducers. This makes it significantly easier to locate structure, bait schools, and fish targets that would otherwise be missed outside of a standard sonar cone.
Yes, this thru-hull model is suitable for fiberglass hulls, provided the hull has a flat mounting surface or a fairing block is used to compensate for the deadrise. Because it is bronze, ensure you use the appropriate isolation materials if installing on a metal hull to prevent galvanic corrosion.
