Simrad B258 Bronze Thru-Hull 9-Pin

The Simrad B258 Bronze Thru-Hull 9-Pin transducer is designed for serious anglers and boaters who require dependable sonar performance in both saltwater and freshwater environments. This bronze thru-hull unit integrates directly into your hull, providing a permanent mounting solution that avoids the performance inconsistencies often associated with transom-mount alternatives.

Constructed from marine-grade bronze, the B258 resists corrosion and maintains signal integrity even in harsh saltwater conditions. The nine-pin connector interface ensures compatibility with Simrad sonar systems and integrated navigation displays, while the thru-hull design minimizes water flow noise and deadband issues that are common with transom units. The bronze construction also aids in heat dissipation, allowing the transducer to operate at peak sensitivity during extended fishing trips.

This transducer is ideal for vessel owners who prioritize long-term sonar performance over casual use. The B258 pairs seamlessly with Simrad's full range of chartplotters and sonar units, providing integrated fish-finding, navigation, and mapping capabilities on a single display, making it an essential tool for serious fishing expeditions.
