Dual frequency transducer for plastic through-hole mounting, 600w power compatible with the new Raymarine a/c/e series instruments.
Factors to consider when choosing a transducer
To determine the transducer best suited to your needs, consider the following factors:
Material The first point to determine is the material the transducer is made of. 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 can damage plastic transducers and cause a leak. Installing a stainless steel transducer in a metal hull requires the use of a fairing, available from your dealer.
DO NOT install a metal transducer on a positive ground vessel.
Mounting type
The type of assembly is also very important.
Thru-hull transducers with fairing blocks offer the best performance, especially at high speeds.
Thru-hull transducers are ideal for towing vessels where good performance is required and there are no protrusions from the hull. Internal transducers are fixed directly inside the hull but performance is slightly reduced. Transducer output power
Output power refers to the intensity at which the transducer sends signals expressed in watts RMS.
Higher power increases the chances of obtaining returns in deep water or poor visibility. It also allows you to see more detail, such as small fish and structure. Typically, the higher the power, the greater the depth you can reach, as well as achieving maximum target separation by eliminating surface clutter.
Frequency The accuracy with which the fishfinder locates the bottom and other objects is also determined by the frequency selected based on depth. Raymarine depth transducers have two frequencies: LOW or 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 greater detail. Typically, fewer unwanted echoes and less clutter are displayed, resulting in greater target definition.
LOW This frequency is used in deep waters. Water absorbs ultrasonic pulses at a slower rate, and larger areas can be covered before the signal becomes too weak. This results in a wider cone angle, allowing for a larger portion of the seabed to be scanned. However, this also means less definition and target separation, and more noise. While low frequencies allow for deeper exploration of the water column, they can also result in a less clear image of the seabed.
In general, you should use the high frequency for a detailed image in shallow water and then switch to the low frequency for greater depths. The ideal solution is to display both frequencies on a split screen.
Angles of the cone The transducer focuses the transmitted waves into a beam. In theory, the pulses are radiated in a cone that widens as the depth increases. In reality, the beam shape varies depending on the transducer, and the pulses are typically also radiated outward, thus producing sidelobes. 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 purposes, we'll consider the image of a cone. The signal is strongest along the centerline of the cone and gradually decreases as we move away from the center. Wider angles show a larger portion of the seabed, but at the expense of resolution because they disperse the transmitter's power. A smaller cone can concentrate the transmission power more in a smaller area. Cone angles are wider at low frequencies and narrower at high frequencies. In summary, a wider beam can detect not only fish directly under the boat but also surrounding fish, but with less target separation. A narrower beam focuses the transmitted energy to more precisely locate small details, such as fish or bottom structure, but scans a smaller portion of water.
DBuongiorno, vorrei acquistare questo prodotto consigliato da voi, ma ho visto che alcuni modelli hanno il connettore diverso da quello che serve a me . Io ho un raymarine es127 con ingresso trasduttore con 7 pin, trasduttore p319 plastico codice A 80171 vorrei essere sicuro che sia questo prima di ordinarlo, grazie e buon lavoro.
R 08/05/2026 Buonasera, esatto, questo articolo è stato creato da noi proprio perchè contiene i cavi corretti per essere compatibile ai display come il suo eS127. Cordiali saluti. Luigi Bianchi
DBuongiorno sig. Bianchi, inizio settimana dovrei acquistare 2 trasduttori
Nelle precedenti email lei mi ha consigliato per il mio strumento raymarine a97, il trasduttore airmar p319 da attaccare direttamente allo strumento tramite il cavo adattatore, inoltre possedendo un modulo raymarine cp 370, e uno switch hs5, quale altro trasduttore posso collegare a questo modulo?
Senza svenarmi......
Calcoli che la mia carena e all'incirca una 26 gradi più o meno
Pensavo ad un trasduttore B117 ma non so se e idoneo per la mia carena
Comunque resto in attesa di vostro cortese riscontro
Cordialmente saluto
Gianluca Daniele
R 13/04/2026 Buonasera, dato che ha una box CP370, allora meglio valutare l'acquisto di un B60 inclinato 20°, prezzo scontato 389,00 euro, sul sito non lo trova, devo inserire io l'ordine, grazie. Cordiali saluti. Luigi Bianchi
Dbuon giorno
doveri ordinarvi questo trasduttore volevo sapere se è disponibile
grazie
R 09-04-22 Buongiorno, sì certo, può procedere all'acquisto, grazie. Cordiali saluti. Luigi Bianchi
