ABSTRACT:
In accordance with an illustrative embodiment of the present invention, a water-proof geophone housing assembly includes a lower body member housing a seismic transducer, a cap member closing the upper end of the lower body member, an upper body member molded over the cap member and an upper portion of the lower body member, there being a molecular bond between all confronting surfaces of the members to prevent entry of moisture. The electrical lead wires extending from the transducer through the cap member and upwardly out of the upper body member are water blocked to prevent migration of water therealong.
