Using FFR technology to produce a standard range of communications transducers with a hemispherical beam pattern, the transducers are ideal for use in a range of underwater communications and acoustic modem applications. As well as producing models tuned to suit popular modem systems, we are able to offer drop-in replacement for transducer models of other companies that may no longer be available on the market.
