Simrad Bronze HDI Thru Hull 50/200/455/800 Khz 9-PIN 12D

The Simrad Bronze HDI Thru Hull 50/200/455/800 kHz 9-PIN transducer represents a versatile choice for anglers and recreational boaters seeking multi-frequency sonar performance in a single through-hull unit. This transducer delivers traditional dual-frequency capability alongside advanced DownScan imaging, enabling fishermen to locate structure, schools, and bottom composition with precision. Whether you're chasing freshwater bass or saltwater species, this Bronze-series transducer integrates seamlessly into existing Simrad systems and fish finders, making it an ideal upgrade or replacement for mid-range vessel electronics.

The four-frequency design operates across 50/200 kHz for traditional sonar and 455/800 kHz for high-definition DownScan imaging, giving you multiple perspectives of the water column in a single pass. The 12-degree tilt angle reduces deadzone immediately beneath the hull, critical for shallow-water presentations and dock fishing. Integrated water temperature sensing provides real-time thermal data to correlate with fish behavior and seasonal patterns. The 33-foot cable with 9-pin connector accommodates most Simrad chartplotters and fish finder models, and the bronze construction resists corrosion in saltwater environments while maintaining signal integrity across extended operational ranges.

This transducer is best suited for recreational and serious sport fishermen running Simrad-compatible electronics who need reliable multi-frequency performance without purchasing multiple transducers. Installation requires a through-hull mount with proper sealant and backing plate; the 9-pin connector type ensures broad compatibility with Simrad's Go, Cruise, and NSS series units. The 15-pound weight and thru-hull design demand careful placement during installation to avoid interference with hull structure or propulsion systems. For boaters upgrading from single-frequency transducers, the combination of traditional sonar and DownScan imaging delivers the detailed bottom mapping and fish-marking capability that defines modern fishfinding.
