B175L BB TH profilált 0°

The CHIRP low-frequency technology used by the B175L transducer emits a continuous sweep of frequencies over a wide band, typically between 40 and 60 kHz. Unlike traditional single-frequency transducers, this approach significantly improves resolution and image clarity. The low-frequency band is particularly effective for detecting targets and distinguishing the seabed at great depths, as it penetrates the water column more effectively.

The Raymarine B175L transducer is a 1 kW (1000 watts) model. This high power provides excellent deep-water penetration and precise target detection, making it ideal for offshore fishing.

The B175L transducer is particularly well suited for deep-sea and deep-water fishing. Its low-frequency CHIRP technology excels in detecting fish and mapping the seabed at great depths, providing detailed visibility where other transducers may lack performance.

The main difference lies in penetration depth and resolution. Low-frequency CHIRP transducers (L), such as the B175L, are optimized for deep water, providing excellent penetration and target detection at great depths. Mid-frequency transducers (M) offer a good balance between depth and resolution, while high-frequency transducers (H) are ideal for shallow waters, delivering very fine resolution and better separation of targets near the bottom or in the upper water column.

The term '0-degree profile' indicates that the transducer is designed to be installed on hulls with a deadrise of 0 to 7 degrees at the installation point. This design ensures that the transducer's ceramic element is parallel to the water surface once installed, guaranteeing optimal sonar performance and accurate bottom reading without requiring additional fairing.

The body of this transducer is made of bronze. Bronze is a robust and durable material, particularly suited to saltwater marine environments, offering excellent corrosion resistance and a long service life.

Although the B175L transducer can operate in shallow waters, its low-frequency CHIRP design is primarily optimized for deep-water performance. For maximum resolution and detection of small targets in very shallow waters, a high-frequency CHIRP transducer would generally be more suitable.

A through-hull installation offers several advantages. It ensures superior hydrodynamic performance, reducing drag and noise generated by water flow, which allows for clearer readings at all speeds. It also minimizes interference and provides a more stable position for the transducer element, ensuring better accuracy and reliability of data, particularly in choppy waters or at high speed.

The Raymarine B175L transducer operates on a low CHIRP frequency range, typically between 40 kHz and 60 kHz. This frequency band is specifically designed to provide maximum penetration and reliable detection in deep water.

Yes, the Raymarine B175L transducer integrates a water temperature sensor. It provides accurate and fast readings of surface water temperature, useful information for fishing and navigation.

No, the Raymarine B175L transducer is a depth and temperature transducer. It does not measure boat speed. To obtain speed data, a separate speed sensor or a GPS system is required.

This transducer is compatible with Raymarine sounder and chartplotter systems featuring CHIRP technology. This includes dedicated CHIRP sounder modules such as the CP470 and CP570, as well as Raymarine multifunction displays (MFD) with integrated CHIRP sounder, such as the Axiom Pro and Axiom 2 Pro series, or other MFDs compatible with an external sounder module.

The Raymarine B175L transducer is equipped with a Raymarine-specific connector (typically 10 pins). Although the Airmar B175L transducer itself is a standard product, its connector is designed for direct compatibility with Raymarine systems. Using it with other brands would require a compatible adapter cable, which is not recommended by the manufacturer and could affect performance or warranty.

Yes, to fully exploit the CHIRP capabilities of this transducer, you will need an external Raymarine CHIRP fishfinder module (such as the CP470 or CP570) or a Raymarine multifunction display with native CHIRP fishfinder functionality. The transducer connects to this module or display to process sonar signals.

The choice of location is crucial for optimal performance. It must be installed in an area where water flow is laminar (without turbulence), away from keels, propellers, propeller shafts, water intakes, and other protrusions that could create air bubbles. Ideally, it should be mounted on the flattest part of the hull, toward the stern and center of the boat, to minimize interference and ensure constant contact with the water.

No, this model is specifically a '0-degree fairing', meaning it is designed for hulls with a deadrise of 0 to 7 degrees at the installation point. For hulls with a more pronounced deadrise, a transducer with a tilted element (e.g., 12° or 20°) would be required to compensate for the hull angle and ensure the sonar beam is directed vertically toward the bottom.

No, the B175L BB TH angled 0-degree transducer is designed to be installed directly through the hull without requiring a fairing or additional shoe to correct the angle. Its 0-degree profile is suitable for hulls with minimal deadrise, allowing flush mounting that minimizes drag and ensures optimal performance.

The transducer must be oriented so that its longitudinal axis is parallel to the boat’s longitudinal axis. This ensures the sonar beam is correctly directed toward the seabed and that the transducer element is aligned with the vessel’s movement for accurate readings. It is important to follow the specific installation instructions to ensure correct orientation.
