Airmar M135C-M Transducer Medium CHIRP Furuno 10-Pin Cable

The Airmar M135C-M Transducer Medium CHIRP Furuno 10-Pin Cable is a purpose-built in-hull transducer designed for serious anglers and boaters who demand reliable depth sensing and fish-finding capability across both offshore and inshore waters. This transducer fills the critical role of delivering real-time sonar data to compatible Furuno chartplotters and fishfinders, enabling you to locate structure, thermoclines, and gamefish with confidence. Whether you're working shallow coastal flats or deeper offshore grounds, this medium-frequency CHIRP unit adapts to diverse water conditions without requiring hull modifications or through-hull drilling.

Operating across the medium CHIRP frequency range of 85–135 kHz, this transducer delivers the signal clarity and range needed for both precision shallow-water work and extended offshore reach. The variable beamwidth—spanning 24° to 16° depending on frequency—narrows as you increase frequency, allowing tighter target definition in deeper water while maintaining broad coverage in shallower depths. At 1 kW of power output, the M135C-M generates strong acoustic penetration and excellent target separation, critical for distinguishing individual fish from baitballs or bottom composition. The in-hull mounting design keeps the transducer protected from impact and fouling while eliminating the need for external installation hardware, making it ideal for fiberglass hulls where internal mounting is practical and preferred.

Anglers using Furuno systems—particularly those upgrading from single-frequency units or adding multi-beam capability—will appreciate the Mix-N-Match cable architecture, which simplifies integration with existing 10-pin Furuno connector wiring. Installation requires positioning the transducer in contact with hull bottom material (typically near the helm or amidships for balanced coverage), ensuring the acoustic face remains parallel to the hull and free of air pockets. This transducer pairs seamlessly with Furuno's NavNet and GPSMap ecosystems, delivering depth-only data that integrates instantly into your navigation and fish-finding workflow, keeping you focused on fishing rather than equipment troubleshooting.
