B175H BB TH profils 12°

The Raymarine B175H BB TH 12-degree fairing is a flush-mounted "Black Box" (BB) through-hull transducer designed to be installed flush with your boat's hull. It features a 12-degree tilted element to compensate for the hull's deadrise angle, ensuring the sonar beam is directed vertically toward the seabed. This is a high-frequency CHIRP transducer (130-210 kHz) optimized for detailed detection of seabeds and small targets.

The Raymarine B175H transducer is a high-frequency CHIRP model, meaning it operates within a frequency range of 130 to 210 kHz. This range is optimized for detailed seabed and small target detection.

The 12-degree integrated tilt is specifically designed to compensate for the deadrise angle of boat hulls. It ensures the sonar beam is directed vertically toward the seabed, even if the hull bottom is angled. This optimizes echo returns and the accuracy of depth data.

The "Black Box" (BB) designation means this transducer is designed to be connected to an external fishfinder module compatible with Raymarine. It does not plug directly into a multifunction display. This configuration provides flexibility in choosing the electronic system and allows integration into complex architectures.

Compared to a transom-mount transducer, the B175H through-hull transducer provides more stable readings and is less affected by water turbulence. Its through-hull installation ensures constant immersion of the transducer element, which is critical for optimal performance while sailing.

Yes, absolutely. The Raymarine B175H is a high-frequency CHIRP transducer (130–210 kHz), making it particularly well-suited for detailed seafloor and small-target detection, with high clarity and precision in returns.

The streamlined design of the B175H transducer reduces hydrodynamic drag, which can contribute to improved boat performance while sailing. It also lowers the noise generated by the transducer during movement, enhancing the quality of sonar data.

The B175H transducer uses CHIRP (Compressed High-Intensity Radiated Pulse) technology. This technology sends a frequency sweep across a wide band rather than a single frequency, providing better resolution and clearer sonar images.

Yes, like most high-quality marine transducers, the Raymarine B175H is designed to operate efficiently in both freshwater and saltwater without compromising performance.

The "H" designation in B175H indicates it is a high-frequency CHIRP transducer (High CHIRP), operating in the 130 to 210 kHz range. The "M" (Medium CHIRP) and "L" (Low CHIRP) designations correspond to different frequency ranges, optimized for specific depths and detection types (M for medium depth, L for deep water).

Yes, the Raymarine B175H BB TH 12° angled transducer is specifically designed for flush-mount installation on the hull. Its tapered design minimizes protrusion and integrates discreetly.

No, the B175H transducer is a "faired" model with a built-in 12-degree tilt. It is designed for flush-mount installation and does not require an external fairing block to compensate for deadrise angle, as the transducer element is already tilted internally.

This transducer is specifically designed for hulls with a deadrise angle between 8 and 15 degrees. The built-in 12-degree tilted element compensates for this angle to ensure the beam remains vertical.

Yes, as a through-hull transducer (Through-Hull or TH), its installation requires drilling a hole in the boat's hull so the transducer element can be submerged and securely mounted.

The 12-degree tilt is built directly into the transducer element. During installation, even if the transducer is mounted perpendicular to the hull’s surface, the internal element is already angled to project the sonar beam vertically toward the seabed, compensating for the hull’s deadrise angle.

Given that installing a through-hull transducer involves drilling the hull and ensuring perfect watertightness, it is strongly recommended to entrust this task to a qualified professional to guarantee a correct and secure installation.

Yes, it is generally recommended to apply antifouling specifically formulated for transducers to the exposed surface of the B175H to prevent marine growth. It is important to use antifouling compatible with transducers and not to paint the active face of the transducer element.

The B175H is a "Black Box" (BB) transducer. It is compatible with Raymarine external CHIRP fishfinder modules, such as the CP470 or CP570 modules, which are designed to process high-frequency CHIRP signals.

No, this transducer is a "Black Box" (BB) type. It cannot be directly connected to a Raymarine multifunction display. It must be connected to an external sounder module compatible with Raymarine (such as a CP470 or CP570), which will then connect to the multifunction display.

The Raymarine B175H transducer is designed specifically to be compatible with Raymarine CHIRP systems. Although it is manufactured by Airmar, it is generally optimized with a connector and electrical specifications for Raymarine sounder modules. Compatibility with other brands is not guaranteed and is generally not recommended without a specific adapter and thorough verification of specifications.
