Airmar B785C Bronze Transducer Medium CHIRP With Navico 9-Pin

The Airmar B785C Bronze Transducer Medium CHIRP with Navico 9-Pin connector is a professional-grade fishfinding solution built for anglers and boaters who demand real-time bottom structure and target detection. This triducer combines depth sensing, fast-response water temperature, and dual-frequency CHIRP sonar into one compact bronze housing, making it ideal for freshwater and light saltwater applications where reliability and clarity matter most. Whether you're mapping structure in a reservoir or tracking schools in a river system, this transducer delivers the responsiveness serious anglers need to stay competitive on the water.

Operating at 600 watts of transmit power across a medium-frequency range of 80 to 130 kHz, the B785C generates a variable beamwidth from 24° at lower frequencies to 16° at higher frequencies—a characteristic that balances wide-area scanning for structure location with tight-cone precision for target definition. The CHIRP technology rapidly sweeps through the entire frequency band rather than transmitting a single pulse, returning multiple echoes that resolve objects with exceptional clarity and separation. Bronze construction resists corrosion in saltwater and brackish environments, while the 9-pin Navico connector ensures seamless compatibility with modern Garmin GPSMAP and other Navico-based chartplotters and fish finders on the market today.

This transducer performs best on center-console and open-hull boats where a transom or trolling motor mount is practical; the integrated temperature sensor makes it invaluable for anglers tracking seasonal thermoclines or seasonal fish movement patterns. Installation requires a standard 9-pin connector plug and runs directly to your compatible Navico chartplotter—no additional adapters or proprietary cables needed. The 7-pound weight and compact form factor minimize drag and integrate cleanly into most modern transom brackets, making it a drop-in upgrade for anglers transitioning from older single-frequency transducers to dual-band CHIRP sonar technology.
