B175H BB TH fairing 20 deg

The CHIRP (Compressed High-Intensity Radiated Pulse) technology integrated in the B175H transducer transmits a frequency sweep over a wide band (130–210 kHz) rather than a fixed frequency. This provides more data, better discrimination of targets (fish) from seabed structures, and increased resolution of underwater details.

The Raymarine B175H transducer operates in the high-frequency (H) band, typically between 130 and 210 kHz. This range is optimized for fish detection and detailed seabed mapping in mid-depth waters.

The B175H transducer is a through-hull (TH) model featuring single-frequency high (H) CHIRP technology. Its internal ceramic element is angled at 20° to compensate for hull deadrise. It is designed to provide excellent target separation and detailed resolution of the seabed.

The B175H transducer is particularly well-suited to anglers targeting pelagic and demersal species who require precise detection in the water column and detailed mapping of bottom structures. Its high-frequency band is ideal for medium depths.

The B175H transducer has an RMS power of 1000 W. This power provides excellent detection and water penetration performance, suitable for sport fishing and navigation.

With its 1000 W power and high-frequency band, the B175H transducer can typically reach detection depths of up to approximately 300 meters (1000 feet) in optimal conditions, though this may vary depending on water salinity and seabed composition.

The Raymarine B175H is a single-frequency transducer. It operates in the high-frequency (H) band from 130 to 210 kHz. While it is single-frequency, the CHIRP technology allows it to sweep this wide band for detailed detection.

Yes, the Raymarine B175H transducer includes a water temperature sensor, allowing this data to be displayed directly on your compatible multifunction display.

"Angled 20 deg" means the internal ceramic element of the transducer is tilted at 20 degrees. This tilt is designed to compensate for the deadrise angle (the V-shape of the hull) of fiberglass boats, which is typically between 16 and 24 degrees, ensuring the sonar beam is directed vertically downward for optimal bottom detection.

The B175H transducer is a through-hull (thru-hull) model designed specifically for installation on fiberglass hulls. It is ideal for boats with a deadrise angle (hull V) between 16 and 24 degrees due to its 20-degree tilted element.

No, thanks to its 20-degree inclined element ("20° fairing"), the B175H transducer is designed to compensate for the hull angle of boats (between 16 and 24 degrees) without requiring an external fairing block. This simplifies installation and reduces drag.

The B175H transducer is compatible with Raymarine multifunction displays (MFDs) equipped with CHIRP sonar technology. This includes the Axiom and Element series, as well as older models such as the gS and eS series, provided they have the integrated or compatible external CHIRP sonar module.

Whether an external sonar module is required depends on the Raymarine multifunction display used. Newer MFDs such as the Axiom Pro/RVX or Element series often have an integrated CHIRP module. For other MFDs, an external CHIRP-compatible sonar module (e.g., CP470 or CP570) may be necessary to fully utilize the B175H's capabilities.

No, the B175H transducer is a traditional CHIRP transducer optimized for bottom and fish detection in 2D view. It is not designed for side imaging (SideVision) or down imaging (DownVision) technologies, which require specific transducers (such as RV-100 or CPT-DV/DS).

Yes, it is possible to connect multiple CHIRP transducers (for example, a B175H for high frequencies and a B175L for low frequencies) to a Raymarine system, provided the multifunction display or external sonar module has the necessary ports and is capable of handling multiple CHIRP channels simultaneously (for example, a CP570). This allows for broader frequency coverage.
