The Airmar B117 is an essential, entry-level dual-frequency transducer designed for leisure yachting and fishing enthusiasts seeking reliable depth and temperature measurements. Featuring a compact, low-profile bronze housing, this transducer minimizes drag and integrates seamlessly into a variety of vessel hulls, making it ideal for boats up to 26 feet with fiberglass or wood hulls. Its nearly-flush design, with only 5 mm (3/16 inch) extending outside the hull, ensures smooth movement through water, reducing turbulence and enhancing stability.

Equipped with a dual-frequency ceramic element, the B117 offers wide-ranging performance. The 50 kHz setting provides a broad 45-degree beamwidth capable of depth detection up to 1,200 feet (366 meters), ideal for open water navigation and deep-sea fishing. The 200 kHz setting delivers a narrower 12-degree beamwidth, allowing for detailed imaging and depth performance up to 700 feet (206 meters). Power output of 600 watts ensures sharp, fast-response readings that improve fish detection and bottom mapping. The transducer also includes a temperature sensor, providing real-time water temperature data crucial for fish behavior analysis.

Designed with space efficiency in mind, the right-angle cable exit protects the cable and simplifies installation in tight compartments. The included rubber washer adapts to irregular hull surfaces, ensuring a secure fit and optimal acoustic coupling. The B117's versatility extends with available models in plastic and stainless steel to accommodate various hull materials. It is suitable for vessels with a maximum deadrise angle of 12 degrees and is compatible with a broad range of marine electronics systems. This durable, reliable transducer is built for leisure and fishing applications, providing dependable performance in both shallow and deep waters. Please note that this product may require direct manufacturer support for returns or warranty issues, as it cannot be returned to the original point of purchase.
