SIMRAD EK60 SCIENTIFIC ECHO SOUNDER In this echograms example, a school of mackerel is observed by simultaneous transmission using 18, 38, 70, 120 and 200 kHz. The frequency response of the mackerel is clearly different documenting the potential of multifrequency acoustics in species classification. Portable scientific system The portable Simrad EY60 is specifically suited for use in a shallow waters, lakes and rivers. The EY60 is the most modern, accurate and easy-to-use fish abundance measurement and fish tracking tool today. It is the same instrument as the Simrad EK60, but set up for outdoor...

HIGH SENSITIVE, HIGH QUALITY TRANSDUCERS In addition to Simrad’s well known 18 and 38 kHz transducers, a range of new transducers with frequencies 70, 120, 200 and 333 kHz have been designed for fishery research applications. These new transducers are all designed using the latest composite ceramics technology. This new design has a much wider bandwidth, and lower sidelobes, than the old traditional transducer design. In addition, smaller physical size and lower weight allow for easier installation and portable use. Except for the 18 kHz transducers, all split beam transducers have 7 degrees...
