Airmar B175C-20-HW 20d Tilt With 8-Pin Garmin MM Cable

The Airmar B175C-20-HW 20° tilted element transducer with Garmin 8-pin MM cable is a professional-grade sounder head engineered for anglers and boat operators who demand reliable bottom detail and water column mapping. After decades on the water, serious fishermen know that transducer performance directly impacts catch rates—the right sounder lets you locate structure, baitfish, and bottom composition in seconds. This wide-beam CHIRP transducer bridges the gap between entry-level and tournament-grade electronics, delivering the responsiveness and clarity needed for both freshwater and saltwater applications.

Built on Airmar's proven B175 platform, this model operates across a high-frequency CHIRP range from 150 kHz to 250 kHz, providing superior target separation and fast-response water-temperature sensing for real-time conditions. The constant 25° beamwidth delivers consistent coverage across depths, eliminating dead zones that plague narrower beam designs—critical when working drop-offs, submerged timber, or hard bottom. The integrated 20° tilted element optimizes sonar geometry for angled transducer mounting on tilting or jackplate systems, maintaining clean signal propagation even at extreme mounting angles. At 12 lbs, it's robust enough for commercial or heavy-use applications yet compact enough for standard through-hull or transom installations.

This transducer is purpose-built for Garmin chartplotters and multifunction displays using the industry-standard 8-pin MM connector, ensuring plug-and-play compatibility with modern Garmin units like the ECHOMAP and STRIKER series. Freshwater bass anglers, saltwater tournament crews, and commercial fishing operators benefit from the fast ping response rate that keeps pace with high-speed trolling or drift presentations. Installation requires proper mounting orientation and attention to deadrise angle compensation—consult your unit's installation guide to maximize sonar performance. For boats running Garmin systems and seeking upgrade performance without replacing the entire electronics suite, the B175C-20-HW delivers tournament-proven sounder capability at a professional price point.
