Know before you buy
The 12-degree tilt compensates for the deadrise of your hull, allowing the transducer to point straight down toward the bottom. This ensures you get an accurate sonar reading rather than a distorted image caused by the angle of the boat.
Yes, this model comes with a 12-pin Garmin Mix-N-Match connector, making it plug-and-play compatible with most modern Garmin sonar units. It also features Xducer ID technology, which allows your display to automatically recognize the transducer and configure the settings for you.
This transducer is optimized for shallow to mid-range depths, providing detailed bottom detection and fish separation down to approximately 700 feet. It is best suited for coastal and inland fishing rather than deep-sea offshore applications.
Yes, the B75C includes a built-in temperature sensor. This allows your compatible Garmin display to show real-time water temperature alongside your sonar data.
Bronze transducers are designed for fiberglass or wood hulls. You should not install a bronze housing on a metal hull, as it can cause electrolytic corrosion; for metal hulls, you would need a stainless steel or plastic housing instead.
The 130 kHz to 210 kHz range provides high-resolution imaging that is excellent for distinguishing between individual fish and underwater structures. By sweeping across these frequencies, it delivers much clearer target separation than a traditional single-frequency transducer.
