FIELD: seismo prospecting. SUBSTANCE: sledge-emitter of non-explosive seismo-source contains two slides interconnected through rigid cross beams mounted for their relative motion. The slides and cross beams are provided with stopping devices of mutual movement to keep the form of the sledges to be constant in the projection of the horizontal plane in a given limits. EFFECT: enhanced efficiency. 2 cl
