The main goal of this paper is to introduce the methodology of preparing the area for investigations that will be carried out at the sea. As the first step there is recognition of the basic method both in the theory as well as experimental investigation. There were taken into account the nonlinear methods. These ones are very promising methods that have very interesting features, very convenient for examinations of the seabed structure. The acoustic beam that is created by nonlinear interaction of two intense beams has very useful phenomenon that allows to use it in such kind of investigation. The main features are as follow - very narrow beam without of sidelobes and relatively low frequency of the radiated pulse. Also it is worth to mention the relatively small dimensions of the transiver set up. Of course we also should remember about the low efficiency of this kind of conversy of elastic energy that equals a few percents.
