Hydrophone Projector TD0280
The Colmar TD0280 is a mid-high frequency spherical hydrophone/projector, suitable for a wide range of applications. As a receiver the frequency usable limits are 5Hz—90kHz., a pre-amplifier is recommended in order to enhance the S/N ratio and make the cable attenuation negligible. As a transmitter TD0280 offers omnidirectional pattern over the transmission resonant frequency bandwidth.
