Detailed description

The through-hull transducer Raymarine B175M BB TH 0° is a bronze 1 kW depth/temperature sounder with CHIRP medium technology, designed for Raymarine installations compatible with CP470/CP570 and 1 kW sounder systems.

CHIRP medium and 0° angle

The CHIRP medium band offers a compromise between range, resolution, and target separation. The 0° angle corresponds to a vertical beam when the transducer is installed on a hull area close to horizontal. This model does not correct for a sloped hull: if the mounting point has a marked deadrise, select a 12° or 20° version.

Bronze through-hull installation

The bronze body is suitable for polyester and wooden hulls. Installation requires checking the actual angle at the mounting point, available thickness, watertightness of the through-hull fitting, and compatibility with the sounder module or display. For B75/B175 mounts, the Raymarine A80328 adapter cable must be verified with the selected configuration.

« B175M BB TH 0° transducer: CHIRP balance for flat hulls »

The Raymarine B175M BB TH 0-degree profiled transducer is a suitable choice for vessels with a 0-degree hull deadrise, typical of flat-bottom or RIB boats. The "0-degree profiled" designation means the transducer’s internal element is pre-angled to compensate for the absence of hull angle, ensuring the CHIRP beam is directed vertically toward the seabed. It is critical to verify the hull deadrise before installation, as using this model on a hull with significant deadrise (e.g., 12 or 20 degrees) would tilt the beam and result in suboptimal fishfinder performance. In such cases, a transducer with the appropriate tilt angle would be required.

This CHIRP medium transducer (B175M) delivers an excellent balance for offshore fishing, covering a wide range of depths without the extreme trade-offs of low-frequency transducers (maximum range, lower resolution) or high-frequency transducers (maximum resolution, limited range). It integrates seamlessly into a compatible Raymarine CHIRP system, and its through-hull installation minimizes exposure to turbulence, optimizing signal quality. It is a reliable option for users seeking a versatile solution for fish detection and bottom mapping without the installation complexity of an external fairing block transducer.

Frequently Asked Questions

Need help? Contact us

What is the RAYMARINE B175M BB TH fairing block 0° transducer?

This is a Raymarine through-hull transducer with a fairing block at 0°, integrating CHIRP medium technology. It is designed for seabed and underwater target detection, providing a versatile solution for navigation and fishing.

What is the output power of this transducer?

The RAYMARINE B175M BB TH fairing 0° transducer has an output power of 1 kW.

What frequency range does the B175M CHIRP medium technology use?

The CHIRP medium technology of this transducer uses a frequency range between 85 and 135 kHz.

What are the advantages of CHIRP medium technology compared to other frequencies?

The B175M's CHIRP medium technology offers an excellent compromise between:

Deep penetration, typically associated with low-frequency transducers.Fine target resolution and echo separation, typical of high-frequency transducers.This makes it versatile for a variety of fishing conditions and depths.

Is this transducer suitable for offshore or coastal fishing?

Yes, the B175M is designed to be versatile and suitable for both coastal navigation and offshore fishing, providing reliable detection in both environments.

Does the B175M provide good discrimination of underwater targets?

Yes, thanks to its CHIRP medium technology, the B175M transducer offers good target discrimination, allowing individual fish and schools to be distinguished.

Can this transducer accurately map the seabed?

Yes, the RAYMARINE B175M BB TH 0° profiled transducer can provide accurate seabed mapping, essential for navigation and fishing zone identification.

Does the B175M transducer include a water temperature sensor?

Yes, this transducer is equipped with an integrated water temperature sensor, providing essential data for analyzing fishing conditions.

What does the "0° faired" marking on this transducer mean?

The "0° faired" marking indicates that the transducer is specifically designed for installation on hulls with a deadrise angle of 0 degrees. This design ensures optimal beam orientation without requiring an additional fairing block.

On which type of hull should the B175M profiled 0° transducer be installed?

This transducer is ideal for flat hulls or those with a 0° deadrise, ensuring optimal performance and simplified installation.

Is it necessary to use a fairing block with this model?

No, thanks to its "0-degree profiled" design, this transducer does not require a fairing block to correct the angle and ensure optimal readings.

Is the B175M a thru-hull transducer?

Yes, the "TH" in its name stands for "Thru-Hull", indicating it is a through-hull transducer installed by drilling through the boat's hull.

Does installing a through-hull transducer require drilling the hull?

Yes, installing a through-hull transducer such as the B175M requires drilling a hole in the boat's hull for the transducer body and cable to pass through.

What are the advantages of a through-hull transducer compared to a transom-mount model?

Through-hull transducers like the B175M offer several advantages:

Less turbulence beneath the transducer, improving signal quality.Better performance at high speed.More stable and accurate seabed readings.

Does the '0-degree profiled' design simplify installation?

Yes, this design greatly simplifies installation on flat hulls by eliminating the need for complex calculations or angular adjustments to properly align the beam.

Which Raymarine systems is this transducer compatible with?

This transducer is compatible with Raymarine multifunction displays equipped with CHIRP technology, ensuring direct integration and optimal use of its capabilities.

Is this transducer compatible with fishfinders from brands other than Raymarine?

No, the RAYMARINE B175M BB TH fairing block 0° transducer is specifically designed for direct and optimal integration with Raymarine CHIRP systems.

Does the B175M transducer require an external fishfinder module with Raymarine multifunction displays?

This depends on the Raymarine multifunction display model. Some recent models integrate a CHIRP fishfinder directly (such as the Axiom Pro or RVX series), while others require an external CHIRP-compatible fishfinder module, such as the Raymarine CP470 or CP570, to operate with this transducer.
