Furuno 1kW Bronze Thru-Hull w/Temp & High Speed Fairing Block

Unlock Superior Underwater Visibility with Precision Engineering

Imagine gliding through open waters at high speeds while your fishfinder delivers razor-sharp images of the seabed and schools of fish below. The Furuno 525TID-BHD sets a new standard for thru-hull transducers, blending rugged bronze construction with advanced dual-frequency technology. Designed for serious anglers and commercial operators on vessels over 26 feet, this powerhouse captures details down to 2,200 feet, making it easier to separate baitfish from keepers and identify structure in murky or deep environments.

What sets it apart? Its innovative ceramic element outperforms older models, offering 25 times the sensitivity of basic single-element designs at 50 kHz. Paired with a high-speed fairing block, it maintains crystal-clear sonar returns even above 30 knots, reducing interference from hull turbulence.

Key Performance Specs That Deliver Real-World Results

• Dual-Frequency Power: Operates at 50/200 kHz with a built-in diplexer, providing wide coverage for offshore scanning (15° x 21° beam at 50 kHz) and pinpoint precision for inshore targeting (3° x 5° beam at 200 kHz).
• High-Power Output: Rated at 1,000 watts, it punches through thermoclines and dense schools, ideal for even entry-level 600W displays to rival pro-grade systems.
• Integrated Temperature Sensing: Real-time water temp data helps track bait migrations and prime fishing zones without extra gear.
• Robust Build: Bronze housing resists corrosion in saltwater, with a 1.2-foot shaft for optimal hull placement.
• Extended Reach: 32.8-foot cable and 10-pin connector simplify integration with Furuno multifunction displays.

Streamlined for speed, the included high-performance fairing block minimizes drag and bubble sweep, ensuring reliable bottom tracking during fast trolling or cruising.

Why Boaters Trust This Transducer for Tough Conditions

In the field, performance matters more than specs. This model excels where others falter—delivering consistent arches on individual gamefish amid bait balls at extreme depths. Users report enhanced target separation in rugged bottom terrain, from rocky reefs to muddy drop-offs. The narrow 200 kHz beam slices through clutter for jigging or wreck fishing, while the broader 50 kHz sweep covers vast areas for trolling spreads.

For high-speed operations, the fairing's hydrodynamic shape keeps the face clean, preventing the "snow" or washout common with lesser setups. It's a favorite upgrade for sportfishing yachts and mid-sized charters chasing pelagics like tuna or billfish.

Seamless Installation and Maintenance Tips

Boat owners appreciate the straightforward thru-hull design—no complex pod mounts or fairings to fabricate. Position it 1/3 aft from the bow along the keel line for best results, ensuring a dead-rise angle match. The 10-pin plug connects effortlessly to compatible Furuno units, and the bronze thru-hull threads securely into standard fittings.

Pro tips: Clean the transducer face seasonally with a soft brush and marine polish to maintain sensitivity. In cold climates, apply antifreeze through the hull fitting to prevent freeze damage. Regular checks on cable strain relief extend its reliable service life.

Ideal Applications for Sport and Commercial Fishing

Perfect for bluewater adventurers probing canyons or inshore pros mapping flats and channels. Pairs seamlessly with Furuno's network of sounders, enhancing CHIRP capabilities for even finer detail. Whether you're bottom bouncing for snapper or live-lining for stripers, this transducer elevates your edge on the water.
