B175M BB TH profiilitud 20°

The Raymarine B175M BB TH faired 20° is a through-hull transducer designed for CHIRP fishfinder systems. It features a 20-degree tilted element, specifically suited for hulls with a deadrise angle between 16 and 24 degrees. The "BB" designation stands for "Black Box", indicating it must be connected to an external Raymarine fishfinder module.

The B175M depth sounder uses CHIRP technology on a mid-frequency band, typically between 85 and 135 kHz. This feature provides an excellent compromise between deep penetration and target separation. It is versatile for coastal and offshore fishing in moderate depths, delivering clear echo returns for identifying fish and underwater structures.

The thru-hull installation of the B175M provides superior hydrodynamic performance as the transducer is directly integrated into the hull, minimizing turbulence and interference. This ensures more stable and accurate depth readings, especially at high speeds, compared to other installation types such as transom-mount transducers.

Thanks to its CHIRP mid-range technology, the B175M fishfinder is particularly well-suited for coastal and offshore fishing in moderate depths. It excels at detecting fish and identifying underwater structures, providing good target separation and balanced deep penetration.

The Raymarine B175M transducer has a power output of 1 kW (1000 Watts). This high power enables it to reach significant depths and provide clear, detailed echo returns, even in challenging conditions.

Yes, the Raymarine B175M transducer is equipped with an integrated water temperature sensor. This allows your Raymarine navigation system to display real-time water temperature, a useful feature for fishing and navigation.

The Raymarine B175M transducer is typically supplied with a standard 10-metre cable. This length is often sufficient for most installations, but it is important to check the distance between the transducer location and the sounder module.

The L, M and H designations refer to the CHIRP frequency band used:

B175L (Low frequency): Excellent deep penetration, ideal for deep waters, but with lower resolution.B175M (Medium frequency): Provides a balanced compromise between deep penetration and target separation, versatile for moderate depths.B175H (High frequency): Delivers fine and detailed resolution, ideal for shallow waters and precise fish identification.The B175M is positioned as a versatile and balanced option.

To maintain optimal performance of your B175M transducer, it is recommended to clean it regularly to remove marine debris, algae, or barnacles that may accumulate on the surface. A gentle cleaning with a soft brush and fresh water is usually sufficient. Avoid harsh chemicals that could damage the transducer.

The B175M profiled transducer with a 20-degree angle is specifically designed for hulls with a deadrise angle between 16 and 24 degrees. The 20-degree angled element compensates for this angle, allowing the transducer beam to point directly toward the seabed, ensuring optimal performance without requiring additional shimming.
