Furuno 525ST-MSD7 Bronze Thru-Hull Multisensor w/7" Stem, 600W, 10-Pin

The Furuno 525ST-MSD7 Bronze Thru-Hull Multisensor w/7" Stem, 600W, 10-Pin is a critical component for serious offshore anglers and commercial mariners who demand precise underwater data. This multisensor provides a comprehensive view of the water column by combining depth, speed, and temperature readings into a single, durable housing. Designed for vessels with thick or cored hulls, the 7-inch stem ensures the sensor can pass through the hull while maintaining structural integrity. It is an essential upgrade for those looking to improve fish finding and navigation accuracy in varied marine environments.

Operating at 600 Watts, this transducer utilizes dual-frequency technology with 50/200 kHz settings to balance deep-water penetration and high-resolution shallow-water detail. The 40-degree beam angle at 50 kHz offers a wide search area for locating schools, while the narrow 10-degree beam at 200 kHz provides sharp target separation and bottom definition. The bronze construction offers superior durability and corrosion resistance compared to plastic alternatives, making it ideal for permanent installation. The unit includes a 30-foot cable and a standard 10-pin connector for seamless integration with compatible Furuno sounders and multi-function displays.

This thru-hull multisensor is particularly effective for fiberglass or wood hulls where a stable, high-performance signal is required even at higher cruising speeds. Boaters will benefit from the real-time temperature and speed data, which are vital for identifying thermal fronts and managing trolling speeds when targeting pelagic species. Professional installation is recommended to ensure the bronze housing is properly seated and sealed for long-term reliability on the water. Whether you are conducting a technical review or looking to buy a replacement, this Furuno multisensor delivers the consistent performance required for demanding marine conditions.
