FIELD: agriculture.
SUBSTANCE: underwater generator of deterrent sounds comprises a source of compressed air, an air duct, a throttle valve, a storage chamber, and a modulator of airflow covered with an elastic cuff. The storage chamber is provided with input and output channels. The modulator is made in the form of a rod. The rod is provided with a blind axial hole. The axial hole is opened into the storage chamber and is communicated with the radial through hole. The cuff consists of two sections of different thickness. The output of the radial hole is located under the cuff part of greater thickness. The part of greater thickness is located from the side of the storage chamber and is provided with the locking means. The free end of the modulator is threaded. The nut and the cap with a hole in the bottom are put on the thread. The nut and the cap have an ability of movement.
EFFECT: increased efficiency of deterring, expanding the scope of application.
