A bi-directional shock and vibration dampener, which affords isolation from undesirable motion in one axis while maintaining positional rigidity on another axis. The invention consists of an attachment with bearings conformed along a shaft to allow axial movement between them. The shaft may be attached with a close tolerance piston centered in a cylinder dividing the cylinder into two chambers. Internal springs and transfer of gas or fluid between chambers achieve bi-directional dampening. Alternately, the dampning effect may be achieved externally to the assembly. In another mount configuration, a gimbal mount with angular deflection sensors and servo drive may be used to maintain desired position relative to horison for motion picture cameras or other equipment. Angular position is held constant while the atachment changes angle on a single plane. Motion picture cameras or other equipment may thus control motion on one axis while maintaining positional stability on another axis
