A device for oscillating and recording seismic waves and prospecting of seismic data was manufd. seismic waves oscillated by a seismic energy force running paralled to the surveying ship and seismic reflection oscillated by parallel setting along the earth surface and compound geophone group were received at uniform intervals an element of two seismic prospecting devices placed compoundly became as the Δe of the parallel interval filtering out only the unnecessary frequency of the special space more effectively.
