Furuno R109LH Transducer

The Furuno R109LH Transducer is a dual-frequency marine sounder designed for serious anglers and boaters who demand reliable fish detection and bottom imaging. Built to handle the demands of both coastal and freshwater fishing, this transducer integrates seamlessly with modern fish-finding systems to deliver consistent performance in varied water conditions.

The R109LH operates on dual frequencies to provide flexibility in different depths and bottom compositions. At higher frequencies, it offers superior target separation and detail on shallow structures, while lower frequencies penetrate deeper water columns and deliver stronger returns on soft bottoms where fish congregate. The 37-pound weight ensures stable mounting and vibration-free performance, critical for eliminating false echoes and noise that can clutter your display.

This transducer is ideal for both saltwater and freshwater applications, making it a versatile choice for various fishing techniques. Installation on most Furuno-compatible systems is straightforward, with standard mounting provisions that work on transom, hull, or through-hull installations depending on your vessel type and preference.
