The OMNI Series geophone provides an unique in-axis sensitivity regardless of tilt angle in space. Each OMNI ele-ment have the same specifications of sensitivity, impedance, phase, frequency response, and harmonic distortion pro-viding an ideal vector fidelity response. The mathematical precision of the resulting measurements significantly im-proves the discrimination of plane wave measurements at the detector.
