Professional Installation & Compatibility

The 525T-BSD features professional marine installation standards with a compact 7/8" shaft requiring only a 22mm through-hull opening. The bronze construction meets ABYC standards for below-waterline fittings and provides excellent electrolytic compatibility with bronze through-hulls and propellers. The transducer accommodates deadrise angles from 0° to 26°, making it suitable for planing hulls, displacement cruisers, and fishing vessels.

Hull Type Compatibility: Designed specifically for fiberglass and wood hulls. Not recommended for aluminum hulls due to galvanic corrosion concerns. Professional installation recommended for optimal performance and warranty compliance.

Enhanced Fishfinding Performance

The dual-frequency operation provides tactical advantages for different fishing and navigation scenarios. The 50 kHz frequency offers superior depth penetration and wide-area coverage ideal for deep water trolling and bottom structure identification. The 200 kHz frequency delivers precise target separation and detailed bottom composition analysis perfect for shallow water fishing and navigation in unfamiliar waters.

Furuno Quality & Support

Backed by Furuno's legendary 70+ year marine electronics heritage, the 525T-BSD includes comprehensive technical support and a limited 3-year manufacturer warranty. The transducer meets CE compliance standards and integrates seamlessly with Furuno FCV-series fishfinders, NavNet systems, and compatible third-party marine electronics.

Frequently Asked Questions

What hull types are compatible with the 525T-BSD transducer?

The 525T-BSD is designed for fiberglass and wood hulls with deadrise angles from 0° to 26°. It's not recommended for aluminum hulls due to galvanic corrosion concerns. The bronze construction provides excellent durability and electrolytic compatibility.

What's the maximum depth capability of this transducer?

The 525T-BSD can accurately measure depths up to 1,200 feet (366 meters), making it suitable for both coastal and offshore applications. Performance may vary based on bottom conditions, water temperature, and electrical interference.

Do I need a fairing block for this transducer?

A fairing block is recommended but sold separately. For vessels operating below 30 knots, the standard fairing (#33-351-01) is adequate. High-performance vessels should use the high-speed fairing (#33-352-01) to minimize cavitation and drag.

Which Furuno fishfinders are compatible with the 10-pin connector?

The 10-pin connector is compatible with Furuno FCV-series fishfinders, including the FCV-588, FCV-628, and newer NavNet systems. Always verify connector compatibility with your specific fishfinder model before installation.

How accurate is the temperature sensor?

The integrated temperature sensor provides accurate water temperature readings essential for fishing thermocline detection and engine cooling system monitoring. Temperature accuracy is typically within ±1°F (±0.5°C) under normal operating conditions.

For over 70 years, Furuno has been continuously imagining and creating new solutions, making new marine electronic equipment with the goal of offering both performance and simplicity for everyone. Not only for men and women who make a living on the seas, but also for those who simply want to enjoy the boating lifestyle. For them, Furuno has become synonymous with quality, performance and reliability.
