Abstract: This invention relates to a system for generating seismic waves. It includes a vehicle for carrying an extensible mast. One end of each of two long stems is pivotally connected to opposite sides of the mast. When the mast is contracted, the stems are in a horizontal travelling position. After the mast is extended, the stems are rotated to a vertical operating position. While the stems are in the vertical position, the mast is retracted which forces the stem several feet into the earth. An air gun, attached to the outer end of the stem, is then actuated to generate a seismic signal. Then the mast is raised, raising the stems and air guns so that it can be readily moved to another location.
