Detailed description

Gáin Raymarine B75H BB TH lögun 0° (A80018) er hönnuð fyrir neðansjávarmælingakerfi sem krefjast lágmarks viðnáms við skrokkinn. Þessi umbreytingarhlutur notar CHIRP-tækni á háum tíðni, með tíðnisviði 130 til 210 kHz, sem veitir nákvæma skráningu botns og skýra aðgreiningu marka í grunnum til miðlungs djúpum vatni.

Hönnun og uppsetning

Með lágmarks viðnáms við skrokkinn (TH) og lágum lögun, minnkar B75H lögun 0° viðnám og tryggir góða vatnsrennsli á mismunandi skrokkum. Innri leirhluturinn er hallandi 0°, sérstaklega hannaður til að jafna út 0° til 7° horn grindar, sem tryggir að sonargeisli stefni lóðrétt niður á botn fyrir bestu árangur. Bronsteinn í líkamanum tryggir endingargetu í kröftugum sjávarumhverfum.

Staðsetning í Raymarine-flokki

Gáin B75H er hluti af B75-flokki CHIRP-umbreytingarhuta frá Airmar, dreift af Raymarine. Hún greinir sig frá B75M (miðtíðni) og B75L (lágtíðni) með því að veita betri upplausn og skýrari aðgreiningu marka í grunnum vatni, vegna há tíðni. Fyrir notendur sem leita að mjög nákvæmri skráningu fiska og bygginga nálægt yfirborði eða botni á miðlungsdjúpi, er B75H rétt val, og fyllir í tækifæri fyrir dýpri vatn eða dreifðari marka sem hinar tíðnir CHIRP veita.

« B75H 0° depth sounder: high-frequency CHIRP precision for low deadrise hulls »

The Raymarine B75H BB TH 0-degree fairing sonar (A80018) is a technical solution for vessels requiring high-precision sonar data acquisition in coastal navigation or sport fishing in shallow to medium-depth waters. Its design as a through-hull transducer with a 0-degree tilted element makes it a relevant choice for hulls with a deadrise between 0 and 7 degrees. The main advantage of this configuration is to ensure a sonar beam perpendicular to the seabed, maximizing echo return quality without losses due to incorrect incidence angle.

In terms of integration, installing this transducer requires precise hull drilling. It is essential to ensure the chosen location has no hydrodynamic turbulence and that interior hull access allows adequate tightening. The bronze body is compatible with most fiberglass or wooden hulls. For metal hulls, galvanic isolation is mandatory. The high-frequency choice (B75H) is strategic for fine detection of underwater structures and individual fish discrimination, offering superior resolution compared to mid- or low-frequency CHIRP transducers (such as the B75M or B75L), which prioritize depth range. However, for very deep fishing applications (>300m), a low-frequency transducer would generally be more suitable.

Frequently asked questions

Need help? Contact us

What is the Raymarine B75H BB TH profiled 0° transducer?

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

Which sonar technology does this transducer use?

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.

What is the frequency range of the B75H transducer?

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 medium waters.

What is the maximum depth at which this transducer can detect?

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

What is the beam angle of the B75H transducer?

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.

What is the material of the transducer housing?

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.

What are the advantages of a high-frequency CHIRP transducer?

The advantages of a high-frequency CHIRP transducer include:

Superior resolution: Enables the distinction of 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 enhances image clarity.

How does the B75H compare to the B75M and B75L models?

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) provide 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).

Is this transducer suitable for sport fishing?

Yes, the Raymarine B75H transducer is particularly well suited to 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.

What type of installation is required for the B75H transducer?

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

For which deadrise angle is this depth sounder designed?

This depth sounder 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.

Does the B75H transducer protrude significantly below the hull once installed?

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.

On which hull types can the B75H bronze transducer be installed?

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.

Is special hull preparation required before installation?

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.

Which Raymarine multifunction displays (MFD) is this transducer compatible with?

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

Is an external fishfinder module required to use this transducer?

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.

Can this transducer be used for navigation or only for fish detection?

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

Is the B75H transducer suitable for powerboats or sailboats?

The B75H transducer is suitable for both types of boats. 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 navigating in various conditions.
