The sensors are equipped with one or more transducers, depending on its function. The acoustic signals are decoded and converted into digital data that is transmitted to a bridge computer for graphical display. Our sounders provides an overall picture of the net, water depth from the surface to the sounder, distance from sounder to seabed, water temperature and a true echogram of fish inside the net.
