B75M BB TH profilovaná 20°

The Raymarine B75M BB TH fairing 20 deg is a CHIRP through-hull transducer from the B75 series. It is designed for bottom and underwater target detection in the mid-frequency band (M) and is specifically suited for hulls with a deadrise angle of 16 to 24 degrees.

This transducer is ideal for demanding sailors and anglers operating across a wide range of depths. Its mid-frequency band provides good fish detection and reliable seabed reading, making it versatile for both coastal and offshore applications.

The "20° tilted" designation indicates that the transducer element of the depth sounder is tilted at 20 degrees. This tilt is designed to compensate for the deadrise angle of deep-V hulls (between 16 and 24 degrees), allowing the acoustic beam to be directed vertically toward the seabed without requiring an external fairing block.

Through-hull transducers (TH) such as the B75M provide optimal readings by minimizing interference and noise compared to transom-mount transducers. They are installed directly through the hull, ensuring direct contact with the water and consistent, reliable acoustic performance, even at high speeds.

Yes, the Raymarine B75M fishfinder uses CHIRP technology. This technology sends a range of frequencies in a single pulse rather than a single frequency, significantly improving target resolution, fish separation, and seabed image clarity.

The "BB" (Black Box) designation means this transducer is intended to be connected to an external Raymarine sounder module, such as the CP370, CP470, or CP570 modules. It cannot be connected directly to a multifunction display without an intermediate module.

The B75M stands out with its mid-frequency band, providing a versatile balance between deep penetration and target separation. The B75L (low frequency) is optimized for very deep waters, while the B75H (high frequency) delivers superior resolution in shallow waters.

The Raymarine B75M BB TH 20° angled transducer, with its CHIRP mid-frequency band, provides excellent deep-penetration capability. While the exact maximum depth depends on many factors (water salinity, seabed type, sounder module power), it is designed for coastal and offshore applications, enabling reliable detection at significant depths.

No, this transducer cannot be directly connected to a Raymarine multifunction display. Its "BB" (Black Box) designation indicates that it requires an external sounder module (e.g., CP370, CP470, or CP570) to process the signals before sending them to the display.

The Raymarine B75M BB TH transducer is designed to work specifically with Raymarine systems compatible with CHIRP and their external transducer modules. Compatibility with equipment from other brands is not guaranteed and is generally not supported.

This transducer features a dedicated Raymarine connector designed to plug directly into their external CHIRP sounder modules (CP370, CP470, CP570).

The Raymarine B75M BB TH angled 20° transducer is specifically designed for hulls with a deadrise angle between 16 and 24 degrees. Its tilted transducer element compensates for this angle to ensure optimal performance.

No, this transducer is designed with an internal transducer element tilted at 20 degrees, allowing it to compensate for the hull’s deadrise angle (between 16 and 24 degrees) without requiring an external fairing block. This simplifies installation and ensures a vertical acoustic beam.

Yes, as a through-hull transducer (TH), installing the Raymarine B75M BB TH with a 20-degree profile requires drilling a hole in the boat's hull to insert the transducer body. It is recommended to use a professional for this installation to ensure watertightness and optimal performance.

For optimal performance, the transducer must be installed in an area free of turbulence, away from propellers, keels, water intakes or any other obstacle that could create air bubbles. The location must also allow easy access for tightening and connection.

Through-hull transducers are typically supplied with basic components for standard installation, such as nuts and washers. It is recommended to check the contents of the packaging or the product documentation to confirm the exact list of included accessories.
