Airmar B164 Thru Hull 12-Degree Transducer
Best thru-hull transducer for small fiberglass or wood fishing boats.
Enhance your fishing experience with the Airmar B60 Thru-Hull Transducer. This 600W dual-frequency transducer features Airmar's Tilted Element technology, ensuring accurate depth readings by correcting for hull deadrise. It operates at 50 kHz for deep water and 200 kHz for shallow detail, providing comprehensive underwater views. Its low-profile bronze housing minimizes drag and protrusion, making it ideal for fiberglass or wood hulls on boats up to 26 feet. The B60 also offers fast-response water temperature sensing for a complete picture of your surroundings.

This transducer is viewed as a critical component delivering reliable results that enhance fishing success, leading to strong user satisfaction.
Know before you buy
The Tilted Element technology allows the transducer to compensate for your boat's hull deadrise internally. This ensures the sonar beam points straight down for accurate depth readings, even when the transducer is mounted on a sloped hull.
No, this bronze housing transducer is designed specifically for fiberglass or wood hulls. Installing it on a metal hull can cause electrolytic corrosion, which will damage the housing and potentially the hull itself.
The 50 kHz frequency provides a wider beam for deep-water searching, while the 200 kHz frequency offers a narrower, high-resolution beam for detailed imaging in shallower water. Using both allows you to switch between broad coverage and precise target identification.
No, the B164 features a low-profile design that sits nearly flush with the hull. This eliminates the need for a fairing block, which reduces drag and makes it an excellent choice for trailered boats.
Under optimal conditions, this transducer can reach depths of up to 366 meters, or approximately 1,200 feet. Performance may vary depending on water conditions, bottom composition, and your specific fish finder unit.
Yes, the B164 includes a built-in, fast-response temperature sensor. It provides real-time water temperature data directly to your compatible fish finder display.
