Abstract
This invention provides a dual gimbal geophone assembly. The geophone is placed in the cavity of a mass member. The mass member is rotatably attached to a frame so that the mass member rotates about a first plane. The frame is rotatably attached to support members so that the frame rotates about a second plane which is orthogonal to the first plane. This geophone provides two degrees of rotation, one along the first plane and the second along the second orthogonal plane. The geophone remains vertical within the tilt tolerance of the geophone regardless of the orientation of the assembly.
