B175M BB TH profils 12°

The Raymarine B175M (reference A80046) is a CHIRP bronze through-hull transducer with a 1 kW output. It is specifically designed for the medium frequency band and features a 12-degree tilted ceramic element, making it ideal for hulls with a deadrise angle between 8 and 15 degrees.

This CHIR transducer operates in the 85 to 135 kHz frequency range. This mid-band offers a balance between deep penetration and target resolution.

The Raymarine B175M transducer has a power rating of 1 kW, providing clear and detailed echo returns for identifying underwater structures and fish schools.

Thanks to its CHIR mid-band technology and 1 kW power, the B175M depth sounder can detect targets and read the seabed in depths up to 600 meters.

CHIRP (Compressed High-Intensity Radiated Pulse) mid-band technology uses a range of frequencies (85–135 kHz for the B175M) to sweep the seabed. This provides better target separation, increased resolution, and more reliable detection of fish and underwater structures compared to fixed-frequency sounders.

This transducer is ideal for boat hulls with a deadrise angle between 8° and 15°. The 12° tilt of the ceramic element compensates for this angle to ensure an optimal vertical beam.

The Raymarine B175M transducer is made of bronze, a durable and corrosion-resistant material, particularly suitable for through-hull installation.

A through-hull fairing block transducer provides a discreet installation with minimal hydrodynamic drag. It ensures optimal performance by being in direct contact with the water, without interference from the hull.

The B175M transducer is compatible with Raymarine CHIR fishfinder modules, such as the CP470 or CP570.

Yes, this transducer is compatible with Raymarine Axiom and Element multifunction displays equipped with CHIR sounder technology.

Yes, the B175M is a versatile solution. Its mid-range frequency band and detection capability up to 600 meters make it suitable for a wide range of applications, from inshore fishing to moderate offshore fishing.

These models differ in their CHIR frequency band:

B175L (Low frequency): 40-60 kHz, excellent for very deep waters.B175M (Medium frequency): 85-135 kHz, versatile for moderate depths and good resolution.B175H (High frequency): 130-210 kHz, ideal for detailed imaging in shallow waters and separating targets close to the bottom.The B175M offers a good compromise for many fishing situations.

No. Thanks to its 12-degree tilted ceramic element, the B175M transducer is designed to compensate for the hull deadrise angle (between 8 and 15 degrees) and delivers a vertical beam without requiring an additional fairing block.

The B175M’s CHIRP mid-band technology provides better target separation, meaning individual fish or schools of fish are displayed with greater clarity and distinction, even at significant depths.

The B175M transducer is specifically designed and configured for Raymarine systems. While the transducer itself is manufactured by Airmar, the connector and specifications are optimized for seamless integration with Raymarine CHIRP-compatible sounder modules and multifunction displays.

The Raymarine B175M transducer (A80046) is typically supplied with a 10-metre cable.

The 12-degree angled element allows the transducer to compensate for the hull deadrise angle. This ensures the depth sounder beam is directed vertically toward the seabed, even if the hull is not flat, providing more accurate and reliable readings.

As a bronze through-hull transducer, the B175M is primarily recommended for fiberglass or wooden hulls. For steel or aluminum hulls, it is generally preferable to use stainless steel or plastic transducers, or to consult the manufacturer's specific recommendations to avoid galvanic corrosion.

Thanks to its high resolution and the clarity of echo returns provided by the CHIRP mid-band technology, the B175M depth sounder allows precise distinction between different seabed structures, whether rocks, seagrass, sediments, or wrecks.
