1. An apparatus for detecting an electric field of a stray voltage anomaly in the presence of a plurality of electric fields, comprising:

  • at least one sensor probe adaptable for mobility about said electric fields, said sensor probe having at least one pair of electrically conductive electrodes for sensing said electric fields;

    an analog to digital converter coupled to said electrically conductive electrodes for digitizing electrical signals received from said sensor probe representative of said electric fields;

    at least one measuring device for determining a location and a speed of said sensor probe;

    a processor coupled to said analog to digital converter and to said measuring device for processing said digitized electrical signals, wherein said digitized electrical signals are averaged commensurate with said speed at which said sensor probe is moving; and

    an interface coupled to said processor having commands for monitoring and controlling said apparatus, said interface providing an audible and visual output for the presence of said stray voltage anomaly detected in said plurality of electric fields.
