In addition to this, the cavitation will generate very strong reverberation, commonly seen as a red stripe of echoes behind the vessel. If you have big problems with cavitation, try to adjust the propeller pitch and/or the number of revolutions. Reverberation Reverberation is generated when the echoes from your sonar transmission are reflected not only by fish and objects in the water, but also from the bottom and the sea surface. Figure 16 Reverberation B A (CD015005E) The echoes from the bottom will vary with how uneven the bottom is, what kind of bottom you have under your vessel, (rock, mud, sand etc. ) as well as your current tilt setting.
