Garmin 010-11937-20 130-210KHZ 0D Tilt Bronze B175H TH 8P

The Garmin 010-11937-20 130-210KHZ 0D Tilt Bronze B175H TH 8P is a professional-grade dual-frequency transducer engineered for serious anglers and marine professionals who demand accurate sonar readings in challenging water conditions. This bronze-constructed transducer operates across both 130 kHz and 210 kHz frequencies, allowing users to switch between low-frequency deep-water scanning and high-frequency shallow-water detail detection. Built for reliability in saltwater and freshwater environments, the B175H is designed to mount securely on fishing boats, research vessels, and commercial marine platforms where downtime is not an option.

This transducer features dual-frequency capability that delivers exceptional performance across varied depths and bottom compositions. The 130 kHz frequency penetrates deeper into the water column, ideal for offshore fishing and surveying applications where range is critical, while the 210 kHz frequency provides superior target separation and bottom detail in shallow to moderate depths. The bronze housing resists corrosion from saltwater exposure and UV degradation, ensuring extended service life without performance degradation. The tilting mount design (0D Tilt configuration) allows precise beam angle adjustment for optimal sonar signal alignment with your boat's hull, compensating for deadrise and ensuring consistent readings regardless of vessel design. With an 8-pin connector interface, integration with compatible Garmin chartplotters and sonar units is straightforward and secure.

Commercial fishing operations, charter boat captains, and tournament anglers rely on the B175H transducer to maintain a competitive edge in fish location and underwater mapping. The dual-frequency design is particularly valuable in transitional waters where fish move between shallow structure and deeper basins throughout the day. Installation requires mounting to the boat hull—either through-hull or transom-mounting depending on your vessel configuration—with the tilting feature allowing compensation for non-standard hull angles. Compatibility is confirmed with Garmin's full range of CHIRP and traditional sonar units featuring 8-pin transducer connectors, making this an ideal upgrade or replacement for existing systems.
