What customers say
Anglers consistently praise the B75C 12 HW for its outstanding clarity and reliable deep water performance. Users report a significant improvement in target separation, making it easier to distinguish fish from structure, even at speed. While the initial investment is substantial, the quality of the returns and the robust build justify the premium price. This transducer is a necessary upgrade for serious offshore fishing, delivering expected results every time. It offers excellent value for dedicated anglers seeking superior performance.
Know before you buy
The 12-degree tilted element is designed to compensate for your boat's deadrise. It ensures the sonar beam points straight down, even when the transducer is mounted on a hull with an 8 to 15-degree angle, providing more accurate readings.
This model comes with a 7-pin Navico Mix-N-Match cable, making it compatible with many Simrad and Lowrance displays. Always verify your specific unit's connector type and CHIRP compatibility before purchasing.
High Wide CHIRP provides a broader view of the water column, which is excellent for tracking baitfish and game fish in shallower to mid-depth waters. It offers superior target separation, allowing you to clearly distinguish individual fish from the bottom structure.
Bronze transducers are intended for fiberglass or wood hulls. You should not install a bronze transducer on a metal hull, as it will cause severe galvanic corrosion.
Yes, it includes a built-in fast-response water-temperature sensor. It provides precise depth readings and real-time temperature data directly to your compatible sonar display.
Xducer ID allows your compatible sonar unit to automatically recognize the transducer and its specific parameters. This simplifies the setup process and ensures your display is configured with the correct settings for optimal performance.
