Furuno 525T-BSD Bronze TH Dept Depth/Temp 10 Pin B45 Housing

The Furuno 525T-BSD Bronze TH Dept Depth/Temp 10 Pin B45 Housing is a marine-grade through-hull transducer engineered for serious anglers and boaters who demand reliable bottom-finding and water-temperature data in demanding saltwater and freshwater environments. This bronze housing unit is built to withstand years of exposure to corrosive marine conditions while maintaining accurate sonar performance. Whether you're running offshore or working shallow coastal flats, the Furuno 525T-BSD delivers the precision depth and temperature readings that separate productive days on the water from wasted fuel and time.

The 10-pin connector design ensures secure, corrosion-resistant signal transmission to your Furuno fishfinder or marine electronics system, while the B45 housing format is the industry standard for through-hull installation on most modern console configurations. Bronze construction provides superior durability compared to plastic alternatives, resisting UV degradation and salt spray that degrades lesser transducers within seasons. The integrated temperature sensor allows real-time water-temperature monitoring, critical for identifying thermal boundaries where game fish congregate and for adjusting trolling speeds based on water conditions. At 3.4 pounds, the transducer is substantial enough for serious offshore work yet manageable for installation on smaller vessels.

This Furuno transducer is ideal for retrofit installations on existing Furuno systems or as a replacement for aging through-hull units that have lost signal clarity or temperature accuracy. The 10-pin configuration is widely compatible with Furuno NavNet and legacy sonar platforms, making it a cost-effective upgrade path for anglers already running Furuno glass. Installation requires a through-hull fitting—professional installation is recommended to ensure proper hull penetration, waterproofing, and cable routing. This transducer excels in both fresh and saltwater applications and will deliver consistent performance for anglers targeting everything from walleye and pike to redfish and grouper.
