Garmin B175M Bronze 12° Thru-Hull Transducer - 1kW, 8-Pin

The Garmin B175M Bronze 12° Thru-Hull Transducer is a 1kW marine sonar transducer engineered for anglers and boaters who demand reliable bottom imaging and fish detection on the water. After years of running electronics in everything from shallow inland lakes to coastal saltwater, you learn that transducer selection makes or breaks your fishfinding capability.

The B175M delivers the depth penetration and target definition serious anglers need to locate structure, baitfish, and game fish with confidence, whether you're working a 20-foot lake basin or dropping down to 500 feet in open water. This bronze through-hull design operates at 1kW output power with a 12-degree beam angle, offering a balanced cone of coverage that excels in both freshwater and saltwater environments.

Tournament anglers, charter captains, and serious recreational boaters benefit most from the B175M's reliable performance across a range of water depths and conditions. The 8-pin connector interface integrates seamlessly with compatible Garmin chartplotters and sonar displays, providing real-time sonar feeds to your helm station. Installation requires professional or experienced DIY hull work—thru-hull transducers deliver optimal performance when installed correctly.
