PRODUCT FEATURES

Using the WBT wideband transceiver unit it simultaneously operates with several different transducers ranging from 12 kHz for the deepest waters up to 500 kHz for very shallow depths. For low frequency transducers below 50 kHz the WBT is available as a high-power system, ensuring enough transmitted power to reach the deepest spots of the ocean.
