FURUNO TRANSDUCER B45 with Fairing Block
600w bronze thru-hull transducer


Frequencies: 50-200khz

Bi-frequency bronze transducer for through-hull mounting, 600w power, echo and temperature, original Airmar compatible with Furuno FCV series fishfinders with 10 pin coonnector.


Product Number: B45

The factors to consider when choosing the transducer
To determine the transducer that best suits your needs, consider the following factors:

Material
The first point to determine is the material of which the transducer is made.
The plastic transducer is recommended for fiberglass or metal hulls.
The stainless steel transducer is recommended for aluminum or steel hulls.
The bronze transducer is recommended for fiberglass or wooden hulls.

Expanding wood could damage plastic transducers and cause a leak. Installing a stainless steel transducer in a metal hull requires the use of a fairing, available from retailers.


DO NOT install a metal transducer on a positively grounded boat.

Mounting type
The type of mounting is also very important.
Thru-hull transducers with fairing blocks offer the best performance, especially at high speeds.
Thru-hull transducers are ideal for tow boats where good performance is required and there are no hull protrusions.
Internal transducers are fixed directly inside the hull but the performance is slightly reduced.
Transducer output power

The output power refers to the intensity at which the transducer sends the signals expressed in watts RMS.

More power increases the chances of returning echoes in deep water or in poor visibility conditions. It also allows you to view more details such as small fish and structures.
Generally, the higher the power, the deeper you can reach, as well as achieving maximum target separation by eliminating surface noise.

Frequency
The accuracy with which the fish finder locates the bottom and other objects is also determined by the frequency selected based on the depth. Raymarine Depth transducers have two frequencies: LOW (low) or HIGH (high).

HIGH
The high frequency is used for shallow water and is used to obtain more accurate readings at high speeds. When using this frequency, the transducer scans a smaller area but displays more detail. Fewer unwanted echoes and less noise are usually displayed with higher target definition.

LOW
This frequency is used in deep water. Water absorbs ultrasonic pulses at a slower rate, and larger areas can be covered before the signal becomes too weak. The result is a wider cone angle that allows you to analyze a larger portion of the seabed. However, this also means less target definition and separation and more noise. Although low frequencies allow you to explore the water column more deeply, they may also result in an unclear bottom image.

In general, you should use the high frequency for a detailed image in shallow water and then switch to the low frequency for greater depth. The ideal solution is to display both frequencies on a double screen.

Corners of the cone
The transducer concentrates the transmitted waves in a beam. In theory, the impulses are radiated into a cone that widens with increasing depth. In reality, the shape of the beam varies according to the transducer and generally the pulses are also radiated outwards thus producing the side lobes. The following figures show a representation of the actual path taken by the pulses.

Low frequencies have a wider beam angle than high frequencies
However, for our purpose, we will consider the image of a cone. The signal is strongest along the center line of the cone and gradually decreases as it moves away from the center. Wider angles show a larger portion of the bottom at the expense of resolution, because they disperse the power of the transmitter. A smaller cone can concentrate the transmit power more in a smaller area. The cone angles are wider at low frequencies and narrower at high frequencies.
To summarize, a larger cone can detect not only fish directly under the boat but also surrounding fish with less target separation. A narrower cone concentrates the transmitted energy to more accurately locate small details, such as fish or bottom structure, but examines a smaller portion of water.


Compact and Budget-Minded! The B45 is Airmar's smallest, bronze, thru-hull stem, offering quality design at an economical price. The classic housing is streamlined to deflect aerated water from the transducer's face, providing solid echo returns. Quality Performance Results Get the most out of a transducer installation. See defined return echoes and clean crisp images. Utilizing Airmar's High-Performance Fairing will boost echosounder performance and provide optimal results for all installations.
D. Il trasduttore furuno b45 in bronzo da 600w con fairing bloc e' compatibile com il furuno fcv627 e con le funzioni discriminazione del fondo e accufish e reezbost? Grazie, saluti.
R. 26-05-23 Buonasera, ho indagato meglio con Airmar, in realtà dalle serie 627 e 628, il B45 è compatibile con entrambi. Ho aggiunto nella sezione Documenti, un file che ne indica appunto le compatibilità: https://www.painestore.it/furuno_trasduttore_b45_bronzo_fairing Cordiali saluti. Luigi Bianchi
R. 25-05-23 Buonasera, compatibile con FCV627, ma non con le funzioni accufish e reezbost, dovrebbe acquistare il 520-5MSD: https://www.painestore.it/furuno_trasduttore_520_5msd Però non ha il sensore della temperatura. Cordiali saluti. Luigi Bianchi
D. Vorrei acquistare un furuno 628 mi servirebbe una sonda in bronzo o plastica con un cono ampio per fare la pesca al tonno io raggiungo fondali max 400 mt cosa mi consigliate grazie in anticipo
R. Buongiorno, Il b45 con fairing block puo' raggiungere con buona definizione 250 300 mt non oltre per pescare alla profondita' che lei ha indicato con definizione buona occorre il b260 https://www.painestore.it/furuno_trasduttore_passante_bronzo_b260
D. Buonasera volevo sapere se posso collegare la mia b45 che era collegata al furuno 585 sul lowrance hds7 b45
R. Buongiorno, può farlo tramite il seguente cavetto Lowrance / fili liberi, dovrà quindi tagliare il connettore del Furuno e collegare i cavetti del cavo proposto: https://www.painestore.it/lowrance_cavo_adattatore_7_pin_blu Cordiali saluti. Luigi Bianchi
D. Buongiorno, volevo sostituire la sonda del mio eco, ho un modulo Eco gsd24 di garmin, mi hanno consigliato questa sonda con fairing. É compatibile? Posso installare questo modello al mio gsd24?
R. Buonasera, preciso che il trasduttore in oggetto non è compatibile con Garmin GSD24, pertanto dovrà valutare la versione per Garmin al prezzo di 449,00 euro Fairing Block incluso. Cordiali saluti. Luigi Bianchi
D. Buongiorno, vorrei acquistare il trasduttore in bronzo B45 + fairing block da abbinare con eco Furuno 627 che ho già. C'è una cosa che non mi è chiara: leggendo le istruzioni di montaggio Airmar del B45 si evidenzia che sarebbe opportuno montare il trasduttore con la "Carenatura ad alto rendimento" (identificata col n. 33-509-01) invece di quella "Standard" (n.33-351-01). Mi sembra di aver capito che questa "Carenatura" sarebbe il "Fairing block". Inserendo questi n. di modello su dei siti americani si vedono due diversi tipi di fairing mentre qui in Italia sembra esistere un unico mod, di Fairing. Quindi, il Fairing block con il trasd B45 che voi vendete insieme a € 254,00 è o ha questa "Carenatura ad alto rendimento"? Grazie
R. Buongiorno, noi trattiamo solo la versione del Fairing block ad alte prestazioni. La versione standard non ha senso valutarla. Cordiali saluti. Luigi Bianchi
D. Buonasera, volevo un trasduttore per il mio ecoscandaglio FCV 620. Pensavo a uno passante in bronzo. Volevo sapere qualche vs alternativa Grazie anticipatamente saluti Picchi
R. Buongiorno, confermo la compatibilità del B45 con FCV620, decisamente il miglior abbinamento. Cordiali saluti. Luigi Bianchi
