Raymarine B258 Bronze High Performance Thru-Hull w/Fairing

The Raymarine B258 Bronze High Performance Thru-Hull with Fairing is a 1000-watt bronze through-hull transducer engineered for serious fishermen who demand accurate depth, temperature, and fish-finding data across extended offshore runs. This high-performance transducer combines bronze construction with integrated temperature sensing, delivering the reliability required in salt water environments where corrosion and durability are non-negotiable concerns.

The 1000-watt output power and fairing block design minimize turbulence and signal loss, critical factors for maintaining sonar clarity at high speeds and deep water depths. Bronze through-hull construction resists salt corrosion significantly better than plastic alternatives, making this transducer suited for vessels operating in challenging marine conditions. The included fairing streamlines water flow around the transducer head, reducing cavitation and maintaining signal integrity even at cruising speeds. Temperature output provides real-time water conditions, helping anglers identify thermal layers and seasonal fish movements. This unit is compatible with a comprehensive range of Raymarine echo sounders, including DSM series, SL Series, hsb2 Plus, and hsb2 HDFI models—ensuring integration with established Raymarine sonar systems already installed on your vessel.

Designed for wood-hulled boats, this transducer is the choice for operators who prioritize long-term reliability and performance consistency. Weekend anglers fishing coastal waters and serious offshore fishermen alike depend on the B258's proven track record for clean sonar imagery and dependable operation. Installation into an existing through-hull housing streamlines the upgrade path for vessels transitioning to higher-power sonar systems.

High-performance bronze transducers represent a meaningful investment in sonar reliability. The B258 delivers the output power, construction quality, and compatibility depth that justifies this commitment for serious boating operations where fish-finding accuracy directly impacts success on the water.
