B75H BB TH perfilada 0°

The Raymarine B75H BB TH profiled 0° transducer is a high-frequency CHIRP transducer designed for underwater detection. It features a discreet through-hull installation and is optimized for precise target separation and detailed seabed detection, particularly in shallow to medium-depth waters.

This transducer uses high-frequency CHIRP (Compressed High-Intensity Radiated Pulse) technology. This technology emits a frequency sweep over a wide band rather than a single frequency, providing superior resolution and better target separation.

The Raymarine B75H transducer operates on a high CHIRP frequency range from 130 kHz to 210 kHz. This frequency band is ideal for detailed detection of structures and fish in shallow to mid-depth waters.

The B75H transducer, with its high-frequency CHIRP range and 600W power, reliably detects down to approximately 183 meters (600 feet) in depth, depending on water and seabed conditions.

The beam angle of the B75H transducer is variable, ranging from 15° down to 9°. This angle narrows as the frequency increases, providing an excellent balance between coverage and fine detail detection.

The Raymarine B75H transducer housing is made of bronze. This material is selected for its robustness and corrosion resistance in marine environments, ensuring a long product lifespan.

The advantages of a high-frequency CHIRP transducer include:

Superior resolution: Allows distinguishing targets very close to each other.Improved target separation: Ideal for identifying individual fish or schools of fish.Detailed detection: Provides a very precise image of the seabed and underwater structures.Less noise: CHIRP technology reduces surface noise and improves image clarity.

The B75H (High frequency) is optimized for target resolution and separation in shallow to mid-depth waters (130–210 kHz). The B75M models (Medium frequency) offer better deep penetration and wider coverage (80–130 kHz), while the B75L (Low frequency) are designed for very deep waters and detection of larger targets (40–75 kHz).

Yes, the Raymarine B75H transducer is particularly well-suited for sport fishing. Its high-frequency CHIRP and ability to provide excellent target separation and detailed detection make it ideal for locating fish, identifying underwater structures, and detecting thermoclines in shallow and mid-depth waters.

The B75H transducer requires a through-hull installation (TH - Through-Hull). This means a hole must be drilled in the boat's hull to insert and secure the transducer, ensuring optimal exposure of the transducer element to the water.

This transducer is specifically designed with an internal ceramic element angled at 0 degrees. It is ideal for hulls with a deadrise angle ranging from 0 to 7 degrees, ensuring the sonar beam is directed vertically toward the bottom for optimal performance.

No, the B75H transducer is designed with a "streamlined" profile. This means it is engineered to minimize drag and ensure hydrodynamic integration on the hull, with minimal protrusion below the boat.

The B75H bronze transducer can be installed on fiberglass or wooden hulls. For metal hulls (aluminum or steel), electrical isolation is required to prevent galvanic corrosion. It is recommended to consult a professional for installation on metal hulls.

Yes, proper hull preparation is essential. This includes selecting the optimal location (away from turbulence, propellers, etc.), drilling the hole precisely according to the manufacturer's specifications, and applying a marine-grade sealant to ensure waterproofing.

The B75H transducer is compatible with Raymarine multifunction displays featuring CHIRP technology, such as the Axiom, Element series, and other compatible models. It requires an external Raymarine CHIRP sounder module to operate.

Yes, the "BB" (Black Box) designation in the product name indicates that this transducer is designed to be connected to an external CHIRP fishfinder module from Raymarine, such as a CP470 or CP570, which then connects to the multifunction display.

While primarily optimized for fish detection and detailed seabed mapping, the B75H depth sounder also provides accurate depth data essential for safe navigation, particularly in shallow or unfamiliar waters.

The B75H transducer is suitable for both powerboats and sailboats. Its low-profile through-hull design minimizes drag for fast powerboats, while its ability to provide accurate depth data is also highly useful for sailboats operating in various conditions.
