B75H BB TH profiliuota 12°

The Raymarine B75H BB TH 12° angled fishfinder transducer is a depth sounder transducer designed to provide highly detailed CHIRP high-frequency detection. It enables better target discrimination, improved fish separation, and precise seabed mapping, particularly useful for sport fishing and navigation in medium to shallow waters.

The B75H transducer uses a high CHIRP frequency band, typically between 130 kHz and 210 kHz. This frequency range is ideal for achieving fine detail resolution and excellent target separation.

CHIRP (Compressed High-Intensity Radiated Pulse) technology provides several significant advantages:

Higher resolution: It allows clearer distinction between individual fish and seabed structures.Improved target discrimination: It helps differentiate fish from algae or other debris.Deeper detection: While this model operates at high frequency, CHIRP technology enhances detection capability compared to fixed-frequency fishfinders.Less noise: It delivers clearer images with fewer interferences.

The « BB » designation stands for « Broadband ». This indicates that the transducer is compatible with CHIRP technology, capable of transmitting across a wide frequency range rather than a fixed frequency, which is essential for CHIRP performance.

Choosing an 'H' (High frequency) transducer like the B75H is beneficial for:

Resolution and detail: It provides superior image resolution and better target separation, ideal for identifying individual fish or fine structures.Shallow to mid-depth waters: It excels in depths under 100–150 meters where detail is critical.'M' (Medium frequency) transducers are a good compromise for varied depths, while 'L' (Low frequency) transducers are preferable for very deep waters and bottom penetration.

No, the Raymarine B75H BB TH transducer is '12° faired'. This means it has a built-in 12-degree angled element designed to compensate for the hull's deadrise angle. It does not require an external fairing block and offers a flush-mounted installation.

The B75H BB TH depth sounder is constructed from bronze. This material is selected for its robustness and exceptional durability in marine environments, providing excellent corrosion resistance.

The B75H transducer, operating at high-frequency CHIRP, can detect depths down to approximately 240 meters (800 feet) in ideal conditions. However, it excels particularly in depths below 100–150 meters, where it provides exceptional detail and resolution for fish detection and bottom analysis.

Yes, absolutely. Thanks to its high-frequency CHIRP technology, the B75H transducer delivers superior resolution and target separation. This allows users to more easily distinguish individual fish, even within schools, and differentiate them from underwater structures.

A 'tilted element 12°' (or tilted element) depth sounder means the transducer element inside the housing is tilted at 12 degrees. This tilt is designed to compensate for the deadrise angle of your boat's hull, allowing the sonar beam to be directed vertically toward the seabed without requiring an external fairing block. This ensures a flush-mounted installation and optimal performance.

The Raymarine B75H BB TH transducer is primarily designed and optimized for marine environments (saltwater) due to its bronze construction and performance characteristics. However, it can also be used in freshwater, providing the same high-frequency CHIRP detection benefits.

The beam angle of the B75H transducer typically ranges between 15 and 9 degrees across its high CHIRP frequency range (130-210 kHz). The beam angle narrows as the frequency increases, providing a tighter beam for improved resolution at higher frequencies.

The B75H transducer is compatible with Raymarine multifunction displays (MFD) featuring CHIRP technology. This typically includes the Axiom, Axiom+, Axiom Pro, and Element series, as well as the eS and gS series when paired with the appropriate CHIRP sounder module (such as the CP470 or CP570).

Whether an external fishfinder module is needed depends on the model of your Raymarine multifunction display. Some modern MFDs, such as the Axiom series, already include an integrated CHIRP fishfinder module. Older MFDs or other systems will require a dedicated external CHIRP fishfinder module, such as the Raymarine CP470 or CP570, to work with the B75H transducer.

No, the Raymarine B75H BB TH transducer is a high-frequency CHIRP Broadband (BB) transducer. It is specifically designed to work with CHIRP-compatible fishfinder systems to fully leverage its wide-band frequency sweep capabilities. It will not function correctly—or at all—with traditional fixed-frequency fishfinder systems.

The B75H profiled 12° transducer is specifically designed for sailboat hulls with a deadrise angle between 8° and 15°. The 12° internal tilt of the transducer element compensates for this angle, ensuring the sonar beam is directed vertically toward the seabed for optimal performance.

The B75H BB TH transducer is made of bronze. Bronze transducers are generally not recommended for direct installation on aluminum or steel hulls due to the risk of galvanic corrosion. For these hull types, it is preferable to use transducers made of plastic or stainless steel specifically designed for this purpose, or to provide adequate isolation if the installation of a bronze transducer is mandatory.
