Raymarine B265LH 1kW Bronze Thru Hull w/Temp

The Raymarine B265LH 1kW Bronze Thru Hull Transducer with Temperature is a dual-function marine sonar transducer engineered for reliable fish-finding and bottom mapping across freshwater and saltwater environments. The bronze construction resists corrosion in salt air and extended immersion, while the 1kW power output delivers strong sonar returns without excessive noise that can spook shallow-water fish. Temperature sensing capability provides real-time water data critical for understanding seasonal fish behavior and locating thermoclines where game fish congregate.

The thru-hull design mounts directly through the hull for permanent installation, eliminating the clutter and mounting complexity of transom-mount alternatives. With 1kW continuous output, this transducer achieves effective sonar penetration to depths suitable for both nearshore and moderate offshore work, balancing power efficiency with detection clarity. The integrated temperature probe eliminates the need for a separate sensor, streamlining electronics installation. Bronze material selection prioritizes longevity in salt-exposed environments where aluminum transducers face accelerated corrosion and steel risked rust staining.

This transducer suits both weekend fishermen running smaller center-consoles and dedicated offshore anglers operating larger displacement vessels. Serious anglers value the temperature data for identifying productive water columns during seasonal transitions—spawning periods, summer stratification, and winter deep-water migration. Recreational boaters benefit from the straightforward installation and reliability of Raymarine's established marine electronics ecosystem, which connects seamlessly to compatible chartplotters and fish finders across their product line.

Raymarine's thru-hull transducers are industry-standard components trusted on commercial fishing vessels, charter boats, and private yachts where equipment failure translates to lost revenue or missed opportunities. The B265LH's bronze construction and proven thermal sensor design reflect decades of marine electronics development focused on real-world reliability in harsh saltwater conditions.
