Detailed description

El pack de dues sondes travesseres Raymarine B175 D/T Low-Medium 20° (referència T70076) està dissenyat per a navegants i professionals que exigeixen un rendiment d’ecosondatge CHIRP de 1 kW. Cada sonda, amb una carcassa de bronze robusta, integra la tecnologia CHIRP en les bandes de freqüències baixa (40-60 kHz) i mitjana (80-130 kHz), oferint versatilitat per a la detecció en aigües profundes i costaneres. El transductor B175LM destaca per la seva capacitat de proporcionar dades de profunditat i temperatura, essencials per a la navegació i la pesca.

Rendiment CHIRP i adaptabilitat

Amb una potència de 1 kW, la sonda B175LM ofereix una resolució de blanc superior i una separació d’ecos millorada respecte a les sondes convencionals de 600 W, com ara la sèrie B75. La banda baixa (40-60 kHz) està optimitzada per a la penetració en aigües profundes, amb un angle de feix variable de 24° a 16°. La banda mitjana (80-130 kHz) assegura una detecció detallada de peixos i estructures en profunditats intermèdies, amb un angle de feix de 16° a 11°. Cada sonda del pack incorpora un element ceràmic inclinat 20°, el qual corregeix l’angle de la carena per a vaixells amb un angle de quilla entre 16° i 24°, garantint així un feix vertical precís per a una lectura òptima.

Integració i posicionament

Aquest pack de sondes s’integra en els sistemes d’ecosondatge CHIRP de Raymarine, especialment als mòduls CP470 i CP570, i als pantalles multifunció de les gammes Axiom i Element Pro. A diferència d’una sonda B75, que ofereix 600W, el B175LM de 1kW està dissenyat per a aplicacions que requereixen més potència i profunditat. La presència de dues sondes idèntiques en aquest pack (T70076) permet configuracions avançades, com l’ús amb dos mòduls sondadors separats per a una cobertura ampliada o redundància, o per a vaixells de gran mida que necessiten múltiples punts de mesura per a una cartografia submarina més completa. Comparat amb transductors com l’Airmar TM150M (600W, tauler posterior, freqüència mitjana única) o el B260 (1kW, bifreqüència fixa, no CHIRP), el B175LM ofereix la modernitat del CHIRP amb una instal·lació travessera discreta i eficient.

« Technical analysis: Raymarine B175 D/T CHIRP 1kW through-hull transducers »

The Raymarine B175 D/T Low-Medium 20° dual through-hull transducer pack is an advanced solution for underwater data acquisition in CHIRP 1kW. Integrating two identical transducers in a single pack is particularly relevant for demanding setups. On large vessels or multihulls, this allows optimized transducer positioning for uncompromised coverage, bypassing potential interference from the keel or other appendages. It is also ideal for installations requiring critical redundancy or powering two independent fishfinder modules, providing increased flexibility for complex navigation and professional fishing systems.

The bronze through-hull installation, while more complex than a transom-mount setup, delivers superior hydrodynamic performance and better protection against turbulence. The 20-degree hull-angle compensation is a key selection factor: it is imperative that the vessel’s deadrise angle matches this specification (between 16 and 24 degrees) to ensure a perfectly vertical beam and accurate readings. Incorrect installation of this parameter would negate some of the benefits of CHIRP technology. For vessels where the deadrise angle does not match, other B175 models (0°, 12°, or versions with fairing blocks) would be more appropriate.

Technically, the B175LM is a versatile 1 kW option. The combination of low and medium bands provides a good balance between deep-water penetration and fine-target detection in intermediate depths. This differentiates it from single-frequency transducers or CHIRP models labeled "High-Wide" that excel in shallow waters but lack range. This pack is therefore a strategic choice for captains seeking a robust, high-performance solution adaptable to specific installation requirements.

Frequently Asked Questions

Need help? Contact us

What exactly is included in the Raymarine B175 D/T Low-Medium 20 deg dual-sonde pack?

The pack (reference T70076) includes two identical Raymarine B175 D/T Low-Medium through-hull transducers with a 20-degree tilted element. Each transducer is a 1 kW CHIRP transducer capable of providing depth and temperature data.

What material is the housing of these depth sounders made of?

Each depth sounder housing is made of robust bronze, ensuring durability and resistance in the marine environment.

What is the purpose of the 20-degree tilt of the ceramic element in the depth sounder?

The 20-degree tilted ceramic element is designed to compensate for the hull angle of vessels. It ensures the fishfinder’s beam is directed vertically toward the seabed, even if the boat’s deadrise angle is between 16 and 24 degrees, thereby guaranteeing accurate and optimal readings.

For which hull types are these through-hull transducers suitable?

These through-hull transducers are designed for installation through the hull of the vessel. They are particularly suited to hulls with a deadrise angle between 16 and 24 degrees, thanks to their 20-degree tilted element that compensates for this angle.

With which Raymarine systems are these B175LM transducers compatible?

These transducers are compatible with Raymarine CHIRP fishfinder systems. They integrate with CP470 and CP570 sounder modules, as well as with the Axiom and Element Pro multifunction displays.

What is the performance difference between the B175LM transducer and a B75 series transducer?

The B175LM transducer delivers 1 kW of power, providing superior target resolution and better echo separation compared to conventional 600 W transducers, such as those in the B75 series. It is designed for applications requiring higher power and deeper penetration capability.

What are the optimal water depths for low and medium frequency bands?

The low-frequency band (40–60 kHz) is optimized for deep-water penetration. The medium-frequency band (80–130 kHz) is ideal for detailed fish and structure detection in intermediate depths.
