dc.description.abstract | Nominal values for the equivalent beam angle are given for several transducers. These are the standard split-beam transducers designed for the SIMRAD EK500 scientific echo sounder, with operating frequencies of 38 and 120 kHz, and the new two-beamwidth SIMRAD ES5 transducer, with operating frequency of 38 kHz. | en |
