Furuno Smart Sensor f/FI50 TH D/T

The Furuno Smart Sensor f/FI50 TH D/T is a dual-frequency transducer engineered for recreational and professional mariners who demand reliable sonar performance and accurate depth/temperature readings. This smart sensor integrates seamlessly with Furuno FI50 fish finders and compatible marine navigation systems, delivering real-time underwater data that improves fishing success and navigation safety. Designed for anglers, charter operators, and boaters who rely on proven marine electronics, this transducer represents Furuno's commitment to precision depth and temperature monitoring in saltwater and freshwater environments.

The Furuno Smart Sensor f/FI50 TH D/T features dual-frequency sonar capability, allowing operators to switch between frequencies for optimal target detection and bottom definition across varying water depths. The integrated temperature sensor provides water column thermal data critical for identifying thermoclines and locating game fish behavior patterns. Built to withstand marine corrosion and harsh saltwater exposure, the transducer housing meets industry durability standards while the DT-800PSF design ensures stable, repeatable signal transmission. Installation requires mounting on the hull or transom, and the sensor connects directly to compatible FI50 display units via standard marine transducer cable interfaces.

This transducer is ideal for boat owners upgrading or replacing existing Furuno sonar systems, particularly those operating in coastal, bay, and deep-water conditions where dual-frequency sonar and temperature monitoring enhance fish-finding effectiveness. The Furuno Smart Sensor f/FI50 TH D/T pairs with all FI50 series display units and legacy Furuno sonar systems supporting DT-series transducers. Proper installation—including hull penetration, cable routing, and electrical connection—ensures maximum signal integrity and sensor longevity. Marine technicians and DIY installers benefit from Furuno's straightforward integration design and comprehensive compatibility with existing vessel electronics.
