B75M BB TH profils 20°

The Raymarine B75M BB TH profiled 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 (M) range and is specifically suited for hulls with a deadrise angle of 16 to 24 degrees.

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

The designation "profilée 20 deg" 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) like 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 transducer 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 depth sounder is designed to be connected to an external Raymarine sounder module, such as the CP370, CP470, or CP570 models. It does not plug directly into a multifunction display without an intermediate module.

The B75M is distinguished by its mid-range 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) offers superior resolution in shallow waters.

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

No, this depth sounder cannot be connected directly to a Raymarine multifunction display. Its designation "BB" (Black Box) indicates that it requires an external sounder module (e.g., CP370, CP470, or CP570) to process 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 is fitted with a dedicated Raymarine connector designed to plug directly into their external CHIRP fishfinder modules (CP370, CP470, CP570).

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

No, this transducer is designed with an internal transducer element angled at 20 degrees, which allows it to compensate for the hull 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 20° profiled transducer requires drilling a hole in the boat's hull to insert the transducer body. It is recommended to have a professional perform this installation to ensure watertight integrity and optimal performance.

For optimal performance, the depth sounder must be installed in a turbulence-free zone, 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 generally 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.
