Garmin 010-11634-22 130-210KHZ 20D Tilt Bronze B75H TH 8P

The Garmin 010-11634-22 130-210KHZ 20D Tilt Bronze B75H TH 8P is a dual-frequency bronze thru-hull transducer built for serious anglers and boaters who demand precise sonar performance in freshwater and saltwater environments. This transducer is engineered to integrate seamlessly with compatible Garmin chartplotters and fishfinders, delivering the imaging clarity needed to locate structure, thermoclines, and active fish at depth. Whether you're running a center console, cruiser, or dedicated fishing platform, this transducer provides the foundation for confident navigation and fish-finding.

Operating across 130 kHz and 210 kHz frequencies, the Garmin B75H delivers high-definition sonar returns with a 20-degree cone angle that balances wide coverage with target definition. The bronze thru-hull housing resists corrosion and galvanic degradation, critical for saltwater installations where aluminum alternatives degrade rapidly. At 6 pounds, the transducer is compact enough for retrofit applications while maintaining the acoustic mass required for reliable signal transmission. The 8-pin connector design ensures proper integration with Garmin's NMEA 0183 and proprietary networking protocols, allowing real-time data sharing across multiple displays and autopilot systems.

This transducer suits both cruising boaters upgrading legacy systems and tournament anglers building new rigs with redundant sonar capability. Installation requires a proper thru-hull fitting with seacock isolation to prevent cabin flooding during routine maintenance. Compatibility with Garmin echoMAP, GPSMAP, and Panoptix-ready models makes it a reliable choice for anyone standardizing on Garmin's ecosystem. Ensure your installation location allows unobstructed water flow and sufficient clearance from the hull bottom for optimal transducer beam geometry.
