Furuno 526T-HDD Bronze Broadband Thru-Hull Transducer w/Temp, Built-In Diplexer & Hi-Speed Fairing Block 1kW (10-Pin)

The Furuno 526T-HDD Bronze Broadband Thru-Hull Transducer with Temperature Sensor, Built-In Diplexer, and Hi-Speed Fairing Block delivers professional-grade sonar performance for serious anglers and offshore boaters. This 1kW transducer combines broadband technology with dual-frequency operation (50/200 kHz) to produce detailed bottom imaging and fish detection across a wide range of water conditions, from shallow bays to deep offshore grounds.

Bronze construction provides superior corrosion resistance in saltwater environments where aluminum transducers fail prematurely. The integrated temperature sensor tracks water conditions in real time, critical for understanding thermal layers where game fish concentrate. The built-in diplexer eliminates the need for external switching logic, simplifying installation and reducing potential points of failure. Beam angles of 20 degrees at 50 kHz and 6 degrees at 200 kHz give you both wide coverage for structure detection and narrow beam precision for tight target identification. The high-speed fairing block (AIR-033-391) reduces turbulence noise at higher vessel speeds, maintaining signal clarity even when running offshore.

This transducer is engineered for anglers targeting pelagic and bottom species, commercial fishing operations, and marine survey work where reliability in demanding saltwater conditions is non-negotiable. The 10-pin connector ensures compatibility with Furuno legacy systems and modern plotters alike. Installation requires thru-hull mounting, permanent integration into the vessel hull at the optimal location for your specific hull design.

Furuno transducers are industry standards in commercial and serious recreational fishing worldwide. The 526T-HDD represents the bridge between legacy broadband technology and modern digital processing, making it a practical upgrade path for experienced boaters maintaining proven systems.
