B175M BB TH profilovaná 12°

The Raymarine B175M (reference A80046) is a CHIR through-transducer in bronze with a power output of 1 kW. 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 over a frequency range of 85 to 135 kHz. This mid-band offers a balance between deep penetration and target resolution.

The Raymarine B175M transducer has a power output of 1 kW, enabling it to provide clear and detailed echo returns for identifying underwater structures and fish schools.

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

CHIRP (Compressed High-Intensity Radiated Pulse) technology in the mid-band uses a frequency range (85–135 kHz for the B175M) to sweep the seabed. This provides better target separation, higher 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 degrees. The 12-degree 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 transducer with a streamlined profile 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 CHIRP sounder technology.

Yes, the B175M is a versatile solution. Its mid-band frequency and detection range up to 600 meters make it suitable for a wide range of applications, from coastal 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 shallow-water imaging 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’s deadrise angle (between 8 and 15 degrees) and ensures an optimal vertical beam without requiring an additional fairing block.

The CHIRP mid-band technology of the B175M 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 fishfinder and multifunction display modules.

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

The 12-degree tilt allows the transducer to compensate for the hull’s deadrise angle. This ensures the depth sounder’s 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 fishfinder allows precise distinction between different seabed structures, whether rocks, seagrass beds, sediments, or wrecks.
