Spherical Transducers
GeoSpectrum’s high-frequency spherical transducers can be used as both transmitters and receivers, offering omnidirectional response and available with resonant frequencies from 12 to 68 kHz and in sizes from 0.5 to 6″ in diameter.
These transducers are ideal for a variety of applications including active and passive sonar, marine mammal detection, and subsea data transmission and communications.
