Abstract
A coupling member for coupling forces generated by a seismic transducer into an elastic medium, such as the earth, wherein the coupling member includes a plurality of discrete cleat members that project downwardly from the lower surface of the coupling member and each of the cleat members has lateral sides, including arcuate portions arranged generally tangent to the sides and to the lower surface of the coupling member whereby the elastic medium is compressed, thereby preventing movement of the coupling member.
