Furuno 526T-HDN Bronze Broadband Thru-Hull Transducer w/ Temp and Hi-Speed Fairing Block, 1kW (No Plug)

The Furuno 526T-HDN Bronze Broadband Thru-Hull Transducer with Temperature and Hi-Speed Fairing Block is a 1kW dual-frequency sonar transducer designed for serious offshore and coastal fishing operations. This bronze thru-hull transducer combines proven broadband technology with integrated temperature sensing, delivering the precise fish-finding capability and structural durability demanded by professional anglers and charter boat operators working in saltwater environments.

The 526T-HDN operates on dual frequencies—50 kHz and 200 kHz—with corresponding beam angles of 20 and 6 degrees. The 50 kHz frequency provides extended range and excellent coverage in deeper water, while the 200 kHz frequency delivers high-resolution target definition in shallow to moderate depths. The 1kW power output ensures strong return signals even in challenging conditions such as rough seas, heavy bottom composition, or when fishing over significant depths. Broadband technology offers superior target separation and reduces the interference issues sometimes encountered with narrowband systems. The included high-speed fairing block (AIR-033-391) minimizes turbulence-induced noise during high-speed operation, critical for maintaining clean sonar returns on fast-moving vessels. The 10-meter cable allows flexible transducer placement and integration with existing hull configurations. The built-in temperature sensor provides real-time water temperature data—essential information for seasonal fishing patterns and thermocline identification.

This transducer suits experienced boaters upgrading to high-performance sonar on vessels 30+ feet where structural integrity and salt-air corrosion resistance justify bronze construction over plastic alternatives. The 526T-HDN integrates with Furuno's full suite of black-box sonar displays and multifunction displays. Installation requires a compatible Furuno sonar processor; the MB1100 may be necessary for certain applications—consult Furuno technical specifications for your specific equipment setup. Note that this unit ships without a connector plug, allowing integration flexibility but requiring proper connector specification during installation.
