B175L BB TH faired 0 deg

La technologie CHIRP basse fréquence utilisée par le transducteur B175L émet un balayage continu de fréquences sur une large bande, généralement entre 40 et 60 kHz. Contrairement aux transducteurs traditionnels à fréquence unique, cette approche permet une résolution et une clarté d'image nettement améliorées. La bande basse fréquence est particulièrement efficace pour la détection de cibles et la distinction du fond marin à de grandes profondeurs, car elle pénètre mieux la colonne d'eau.

The Raymarine B175L transducer is a 1 kW (1000 watts) model. This high power provides excellent deep-water penetration and precise target detection, making it ideal for offshore fishing.

The B175L transducer is particularly well suited to deep-sea and deep-water fishing. Its low-frequency CHIRP technology excels at detecting fish and mapping the seabed at great depths, providing detailed visibility where other transducers may lack performance.

The main difference lies in penetration depth and resolution. CHIRP low-frequency (L) transducers, such as the B175L, are optimized for deep water, offering excellent penetration and target detection at great depths. Medium-frequency (M) transducers provide a good balance between depth and resolution, while high-frequency (H) transducers are ideal for shallow water, delivering very fine resolution and better separation of targets near the bottom or in the upper water column.

Le terme 'profilé 0 degré' indique que le transducteur est conçu pour être installé sur des coques ayant une inclinaison (deadrise) de 0 à 7 degrés au point d'installation. Cette conception assure que l'élément céramique du transducteur est parallèle à la surface de l'eau une fois installé, garantissant une performance sonar optimale et une lecture précise du fond sans nécessiter de carénage supplémentaire.

This transducer's housing is made of bronze. Bronze is a robust and durable material, particularly suited to saltwater marine environments, offering excellent corrosion resistance and long service life.

While the B175L transducer can operate in shallow waters, its low-frequency CHIRP design is primarily optimized for deep-water performance. For maximum resolution and fine-target detection in very shallow waters, a high-frequency CHIRP transducer would generally be more suitable.

A through-hull installation offers several advantages. It ensures superior hydrodynamic performance, reducing drag and noise generated by water flow, which allows for clearer readings at all speeds. It also minimizes interference and provides a more stable position for the transducer element, ensuring better accuracy and reliability of data, especially in choppy waters or at high speeds.

The Raymarine B175L transducer operates on a low-frequency CHIRP range, typically between 40 kHz and 60 kHz. This frequency band is specifically designed to provide maximum penetration and reliable detection in deep waters.

Yes, the Raymarine B175L transducer includes a water temperature sensor. It provides accurate and rapid surface water temperature readings, useful for fishing and navigation.

No, the Raymarine B175L transducer is a depth and temperature transducer. It does not measure boat speed. To obtain speed data, a separate speed sensor or GPS system is required.

This transducer is compatible with Raymarine fishfinder and chartplotter systems featuring CHIRP technology. This includes dedicated CHIRP fishfinder modules such as the CP470 and CP570, as well as Raymarine multifunction displays (MFD) with integrated CHIRP fishfinder, such as the Axiom Pro and Axiom 2 Pro series, or other MFDs compatible with an external fishfinder module.

Le transducteur Raymarine B175L est équipé d'un connecteur spécifique à Raymarine (généralement 10 broches). Bien que le transducteur Airmar B175L lui-même soit un produit standard, son connecteur est conçu pour une compatibilité directe avec les systèmes Raymarine. L'utilisation avec d'autres marques nécessiterait un câble adaptateur compatible, ce qui n'est pas recommandé par le fabricant et pourrait affecter la performance ou la garantie.

Oui, pour exploiter pleinement les capacités CHIRP de ce transducteur, vous aurez besoin d'un module sondeur CHIRP externe Raymarine (comme le CP470 ou le CP570) ou d'un écran multifonction Raymarine intégrant nativement un sondeur CHIRP haute performance. Le transducteur se connecte à ce module ou à l'écran pour traiter les signaux sonar.

The choice of location is crucial for optimal performance. It must be mounted in an area where the water flow is laminar (without turbulence), away from keels, propellers, propeller shafts, water intakes, and other protrusions that could create air bubbles. Ideally, it should be installed on the flattest part of the hull, toward the stern and center of the boat, to minimize interference and ensure constant contact with the water.

No, this model is specifically '0-degree fairing', meaning it is designed for hulls with a deadrise of 0 to 7 degrees at the installation point. For hulls with a steeper deadrise, a transducer with a tilted element (for example, 12° or 20°) is required to compensate for the hull angle and ensure the sonar beam is directed vertically toward the bottom.

No, the B175L BB TH 0-degree profiled transducer is designed to be mounted directly through the hull without requiring additional fairing or shoe to correct the angle. Its 0-degree profile is suitable for hulls with minimal deadrise, allowing flush mounting that minimizes drag and ensures optimal performance.

The transducer must be oriented so that its longitudinal axis is parallel to the boat’s longitudinal axis. This ensures the sonar beam is correctly directed toward the seabed and the transducer element is aligned with the vessel’s movement for accurate readings. It is important to follow the specific installation instructions in the manual to ensure correct orientation.
