Garmin 010-11939-20 85-135KHZ 0D Tilt Bronze B175M TH 8P

The Garmin 010-11939-20 85-135KHZ 0D Tilt Bronze B175M TH 8P transducer is purpose-built for serious anglers and boaters who demand high-frequency sonar performance in freshwater and saltwater environments. This bronze through-hull transducer delivers the precision fish-finding capability that professional and recreational boaters rely on to locate structure, thermoclines, and suspended species at depth.

Operating across the 85–135 kHz frequency band, the Garmin B175M delivers dual-frequency capability that balances wide coverage with detailed target definition. The bronze construction resists corrosion from prolonged saltwater exposure while maintaining acoustic clarity, and the 0D tilt adjustment accommodates various hull angles without sacrificing beam projection.

At 11.6 pounds, this through-hull design requires permanent installation but provides superior transducer stability compared to transom-mounted alternatives, eliminating vibration and cavitation that plague externally mounted units in rough water. The 8-pin connector links directly to Garmin's full sonar ecosystem, making this transducer ideal for upgrades to existing systems or new installations on center-console and larger recreational vessels.
