Airmar B175C-12-HW Transducer High Wide Beam 12 Deg Tilt

The Airmar B175C-12-HW Transducer High Wide Beam 12 Deg Tilt is a dual-frequency transom-mount sonar head built for anglers and boaters who demand precise bottom mapping and fish detection in shallow to moderate depths. This transducer is engineered to deliver consistent performance across freshwater lakes, rivers, and coastal waters where a wider beam angle matters more than pinpoint vertical resolution. If you're running a mid-size recreational fishing vessel, pontoon, or aluminum center console and need reliable sonar without breaking the bank, this Airmar transducer delivers the imaging clarity that experienced boaters depend on.

The 12-degree high-wide beam design casts a broader cone of sonar energy compared to narrow-beam alternatives, covering more water column and lakebed in a single ping—ideal for finding structure, schools of baitfish, and suspended targets in open water. The transom-mount installation places the transducer flush against the hull below the waterline, minimizing turbulence and signal loss while the 12-degree tilt helps compensate for hull deadrise and eliminates cone shadowing caused by the boat's running attitude. Airmar's proven construction and ceramic element technology ensure years of reliable service in both saltwater and freshwater environments when properly installed and maintained.

This transducer is compatible with most Garmin, Lowrance, and Simrad chartplotters that accept Airmar dual-frequency heads via standard sonar connector ports. Installation requires a clean transom mounting surface, proper sealant, and correct cable routing to avoid chafing or signal interference. Boaters upgrading from older single-frequency units will immediately notice the depth range and bottom contrast improvements, especially in weedy or structured environments where the wide beam's coverage advantage shines. Weighing 12 pounds and designed for permanent transom mounting, the B175C-12-HW is the go-to choice for serious anglers who refuse to compromise on sonar reliability.
