A hydrophone free from internal leads and further including a stabilizing jacket is described. The hydrophone uses the metallic end caps of the stabilizing jacket to complete the circuit thereby eliminating the need for internal leads. Further, the stabilizing jacket results in a hydrophone configuration that can withstand harsher conditions while nonetheless providing excellent detection capabilities.

A dual core geophone includes a dual magnetic core packaged in a housing providing higher sensitivity and a reduction of electric wires in the device. The geophone includes a locking mechanism for the dual magnetic core to protect the device from strong vibrations when the device is not in use. A method for measuring acoustic vibrations in a downhole with a dual core geophone as above includes locking the dual magnetic core when the geophone is not detecting acoustic vibrations.
