The Furuno 520-5PSD and 520-5MSD are mid-range thru-hull transducers designed for clear, dual-frequency sonar operation at 600 watts. Both models operate at 50/200 kHz frequencies with 46° and 10° beam angles for broad area and precision scanning. The 520-5PSD features a durable plastic housing, while the 520-5MSD employs robust bronze construction for durability and reliability.
