Furuno T-04MSB Bronze Thru-Hull Temp Sensor - 6-Pin

The Furuno T-04MSB Bronze Thru-Hull Temperature Sensor is a precision marine-grade instrument designed to deliver accurate water temperature data directly to your fishfinder, chartplotter, or marine display system. This 6-pin connector model combines bronze housing durability with reliable thermal sensing, making it the standard choice for both recreational anglers and serious offshore fishing operations seeking real-time water condition monitoring.

The thru-hull installation design ensures direct water contact for immediate temperature readings, eliminating lag that can occur with indirect sensing methods. Bronze construction resists corrosion in saltwater environments—a critical advantage for boats operating in coastal and offshore waters where galvanic corrosion can compromise sensor longevity. The 8-meter cable provides flexible installation routing through most hull configurations, while the 6-pin connector integrates seamlessly with Furuno sounder and navigation equipment. This sensor reads across the full operational range needed for fishery management, thermal layer identification, and seasonal species migration patterns.

Anglers targeting structure-dependent species benefit from precise temperature data, as many game fish concentrate near specific thermal zones. The T-04MSB integrates with Furuno's proprietary sounder systems, displaying temperature alongside bottom composition and fish marks—essential information for trophy hunters on freshwater lakes, coastal fisheries, and deep-water applications. Maintenance crews and commercial operators also rely on this sensor for engine cooling system diagnostics and environmental compliance monitoring. Whether you're upgrading an aging sensor or installing a new sounder package, this Furuno temperature sensor provides the accuracy and durability expected from Japan's leading marine electronics manufacturer.
