B175HW/12 - 1 kW Bronze CHIRP Thru-Hull Transducer

The CHIRP High-Wide (HW) technology enables the fishfinder to scan a wide range of frequencies (150–250 kHz) for superior fish detection and detailed seabed discrimination. The term 'High-Wide' refers to a constant wide beam of 25° across the entire frequency range, providing coverage under the boat that is twice as large as traditional narrow-beam transducers.

The Airmar B175HW/12 transducer operates over a High CHIRP frequency range of 150 to 250 kHz.

The B175HW/12 transducer has a transmit power of 1 kW (1000 Watts).

The Airmar B175HW/12 transducer can reach a maximum depth of 152 metres (approximately 500 feet) for detection.

This transducer provides accurate readings of depth and water temperature, with a fast response.

A wide and constant 25° beam (High-Wide) provides coverage under the boat that is twice as large as traditional narrow-beam transducers. This significantly improves fish detection in the upper water column and allows for more efficient exploration of larger areas.

This transducer is recommended for boats between 8 and 11 meters (25 to 36 feet) in length.

The B175HW/12 depth sounder housing is made of bronze.

Yes, the B175HW/12 transducer is equipped to provide depth and water temperature readings.

The depth sounder cable is 9 meters long.

Airmar Xducer ID® technology is an exclusive Airmar feature that enables automatic identification of the transducer by a compatible fishfinder, simplifying setup and optimizing performance.

Yes, the high-frequency CHIRP band (150-250 kHz) of this transducer provides excellent resolution, which is particularly suited for shallow-water performance, detailed seabed discrimination, and precise target separation.

Installing the B175HW/12 transducer requires drilling a 95 mm (3-3/4 inch) hole in the hull.

The bronze housing of the B175HW/12 depth sounder is specifically designed for fiberglass or wooden hulls.

The 12° tilted element of the transducer is designed to compensate for keel angles of boats ranging from 8° to 15°. This ensures the transducer beam is oriented horizontally relative to the seabed, optimizing detection and the accuracy of readings.

The Airmar B175HW/12 transducer is a through-hull type, meaning it is installed by drilling a hole in the boat's hull.

The Tilted Element™ technology allows the internal ceramic element of the transducer to be tilted at a specific angle (12° here) relative to the mounting surface. This ensures the sonar beam is directed straight to the seabed, even if the boat’s hull has some keel angle, optimizing sonar performance without requiring a fairing block.

Yes, for proper operation and to fully exploit its CHIRP capabilities, the B175HW/12 fishfinder must be connected to a compatible fishfinder module or multifunction display with CHIRP support.

The Airmar B175HW/12 transducer is compatible with fishfinders and multifunction displays that support CHIRP technology up to 1kW and are designed to work with Airmar transducers. It is essential to verify the connector compatibility of the transducer with your specific equipment.

No, the bronze housing of this depth sounder is not recommended for installation on aluminum hulls. Bronze can cause galvanic corrosion with aluminum. This depth sounder is specifically designed for fiberglass or wooden hulls.
