Furuno 165T-50/200-SS260 1Kw Thru-Hull for DFF3D

The Furuno 165T-50/200-SS260 1Kw Thru-Hull for DFF3D is a high-performance dual-frequency transducer designed for serious anglers and professional boaters who demand precise sonar imaging in demanding saltwater and freshwater environments. This transducer serves as the core sensing element for the Furuno DFF3D fish finder, delivering real-time bottom structure, fish location, and water column data to your helm. Whether you're targeting deep-water species, navigating coastal channels, or surveying shallow flats, this transducer bridges the gap between raw sonar technology and actionable fishing intelligence on your display.

Built with stainless steel (SS260) construction, the Furuno 165T-50/200-SS260 resists corrosion and maintains acoustic integrity through seasons of saltwater exposure. The 1 kilowatt power output provides excellent penetration and resolution across both the 50 kHz and 200 kHz frequencies, allowing simultaneous wide-angle scanning at lower frequencies for structure detection and narrow-beam high-frequency imaging for precise fish target separation. The thru-hull installation design minimizes drag while maintaining optimal transducer face angle for consistent beam transmission—critical when hunting bottom composition changes or suspended baitfish schools across varying depths and water temperatures.

This transducer is engineered specifically for integration with Furuno's DFF3D platform, ensuring seamless signal processing and display optimization without compatibility guesswork. The 24.4-pound weight requires proper thru-hull mounting with adequate hull reinforcement, particularly for vessels under 30 feet, and professional installation is strongly recommended to prevent leaks and ensure correct beam alignment. Experienced anglers working offshore structures, deep drop-offs, and hard-bottom zones will appreciate the dual-frequency capability, while charter operators and competitive fishermen rely on this transducer's reliability to maintain their edge in demanding conditions season after season.
