Detailed description

Hönnuð fyrir kröfuharða siglingamenn og veiðimenn, er Raymarine B75M BB TH lögun 20° þvermælirinn CHIRP sem fer í gegn úr B75-seríunni. Þessi gerð er sérstaklega hönnuð fyrir kúptar skrofa með deadrise horn (tonture) á milli 16 og 24 gráða, vegna hallandi þvermælis sem jafnar þetta horn án þess að nota sérstakt lagnaðarhlut. Hún veitir nákvæma botn- og undirvatnsmarkmiðagreiningu á miðbylgjubandi (M).

Staðsetning og innsetning

B75M greinist frá öðrum CHIRP þvermælum úr B75-seríunni, svo sem B75L (lágbylgja fyrir djúpvatn) eða B75H (hágbylgja fyrir skilgreiningu í grunnu vatni), með því að veita fjölhæft miðbylgjuband. Þetta bylgjuband veitir jafnvægi milli djúpinntrengingar og markmiðaskilnaðar, sem gerir það heppilegt fyrir fjölbreyttar strand- og úthafsnotkunar. Merkingin "BB" (Black Box) bendir til þess að þetta sé ætlað til tengingar við ytri þvermælis módúl frá Raymarine, svo sem CP370, CP470 eða CP570, fremur en beint við fjölnota skjá.

Hönnun og uppsetning

Sem þvermælir sem fer í gegn (TH), tryggir Raymarine B75M BB TH lögun 20° bestu mögulegu lesi með því að minnka truflanir og hávaða miðað við afturborðsmæla. Lögunin á 20° einfaldar uppsetningu á djúp-V skrofa með því að stilla bylgjuna nákvæmlega með botninum án þess að þurfa flókin viðbætur eða hluti til að leiðrétta horn. Þetta tryggir stöðuga og áreiðanlega hljóðfræðilega frammistöðu, sem er mikilvægt fyrir siglingar og veiðar.

« Technical analysis: Raymarine B75M profiled 20° transducer »

The Raymarine B75M BB TH fairing block transducer with a 20° deadrise angle is a strategic choice for vessels whose hull deadrise angle falls between 16° and 24°. Its main advantage lies in its "fairing block" design, which incorporates the deadrise angle compensation directly into the transducer element. This eliminates the need for an external fairing block, simplifying integration and reducing the risk of snagging or damage for high-speed boats or those operating in cluttered areas. The medium-frequency (M) CHIRP band offers versatile performance, providing adequate depth penetration for moderate depths while maintaining sufficient resolution to identify structures and fish schools.

Integrating this transducer requires a dedicated Black Box sounder module, such as the Raymarine CP370, CP470, or CP570. This architecture allows signal processing to be offloaded, offering flexibility in the choice of compatible multifunction displays. It is critical to note that this transducer is not suitable for flat-bottom hulls (0-7° deadrise) or hulls with a very steep angle (over 25° deadrise), for which other through-hull transducer models with different deadrise angles or external fairing blocks would be more appropriate. For optimal performance, careful installation with precise drilling and watertight sealing is essential.

Frequently asked questions

Need help? Contact us

What is the Raymarine B75M BB TH profiled 20 deg transducer?

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) band and is specifically suited for hulls with a deadrise angle of 16 to 24 degrees.

For which types of boats or activities is this depth sounder ideal?

This depth sounder 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 various coastal and offshore applications.

What does "profilée 20 deg" in the product name mean?

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.

What are the advantages of a through-hull transducer (TH) like the B75M?

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.

Does the Raymarine B75M transducer use CHIRP technology?

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.

What does the "BB" (Black Box) designation mean for this transducer?

The "BB" (Black Box) designation means this transducer is designed to connect 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.

How does the B75M compare to the other transducers in the B75 series (B75L, B75H)?

The B75M stands out with 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) delivers superior resolution in shallow waters.

What is the depth capability of the Raymarine B75M BB TH transducer?

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

Can this transducer be connected directly to a Raymarine multifunction display?

No, this transducer 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 the signals before sending them to the display.

Is this transducer compatible with equipment from brands other than Raymarine?

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

What type of connector does this transducer use to connect to the fishfinder module?

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

For which deadrise angle is this transducer suitable?

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

Is an external fairing block required with this transducer?

No, this transducer is designed with an internal transducer element tilted 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.

Does installing this transducer require drilling through the boat hull?

Yes, as a through-hull transducer (TH), installing the Raymarine B75M BB TH 20° profiled model requires drilling a hole in the boat hull to insert the transducer body. It is recommended to have a professional perform this installation to ensure proper sealing and optimal performance.

What are the important considerations for choosing the installation location of the depth sounder?

For optimal performance, the depth sounder 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.

Is the transducer supplied with the necessary mounting hardware?

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.

How can I obtain information about the warranty for this Raymarine depth sounder?

To obtain detailed information about the warranty for the Raymarine B75M BB TH 20-degree profiled depth sounder, it is recommended to consult the documentation provided with the product or visit the official Raymarine website. The warranty terms are specified by the manufacturer.
