B75H BB TH profilată 20°

The Raymarine B75H BB TH 20-degree profiled transducer has a power output of 600 watts.

"20-degree tilted" means the internal element of the transducer is tilted by 20 degrees. This design is specifically suited for boat hulls with a deadrise angle of 16 to 24 degrees, allowing the sonar beam to be directed vertically toward the seabed for optimal detection.

Through-hull transducers, such as the B75H BB TH, typically offer better performance, especially at high speeds, as they are less prone to turbulence and hydrodynamic interference. They provide more stable and accurate readings because the transducer is in direct contact with the water beneath the hull.

Yes, the Raymarine B75H BB TH transducer is a high-frequency CHIRP transducer, which provides better target separation and increased resolution compared to single-frequency transducers.

The B75H transducer is typically made of bronze for its durability and corrosion resistance in a marine environment.

The maximum detection depth of the B75H BB TH transducer depends on several factors, including water salinity, seabed conditions, and the power of the sounder module used. However, as a 600W high-frequency CHIRP sounder, it is optimized for depths up to approximately 180–270 meters (600–900 feet) in ideal conditions.

This transducer is specifically designed to be installed on V-hulls with a deadrise angle between 16 and 24 degrees. The 20-degree tilted element compensates for this angle to ensure a vertical beam.

No, the streamlined design of the internal element of the B75H BB TH 20-degree transducer eliminates the need for an external fairing block to compensate for the keel angle. It is installed directly through the hull.

The B75H transducer is typically made of bronze. Its installation is ideal on fiberglass hulls. For other hull types, specific precautions are required:

Wooden hulls: Special attention to watertightness and protection against rot is required.Metal hulls (aluminum, steel): Electrical isolation is essential to prevent galvanic corrosion. Installation must be performed by a professional.It is always recommended to consult a professional for these types of installations.

Yes, several precautions are essential:

Location: Choose a spot on the hull free from turbulence, away from propellers, keels, water intakes, and any other protrusions.Waterproofing: Ensure perfect sealing around the transducer to prevent water infiltration into the hull.Professional installation: It is strongly recommended to use a professional installer or to strictly follow the installation manual provided by the manufacturer.

To maintain the depth sounder's optimal performance, it is recommended to clean it regularly to remove any buildup of marine fouling (algae, barnacles). Use a soft brush and water to avoid damaging the transducer surface. Do not use abrasive products or solvents.

The Raymarine B75H BB TH transducer is designed with a specific connector for Raymarine CHIRP-compatible fishfinder modules (CP370, CP470, CP570). Using it with modules from other brands would require an adapter or cable modification, which is not recommended and could void the warranty.

No, the B75H BB TH transducer is a CHIRP transducer and requires a compatible fishfinder module and multifunction display with CHIRP technology to operate correctly. It will not be compatible with older single-frequency sounders.
