1. A magnetic locator device, comprising:

  • a housing element;

    a first three-axis magnetic sensor device disposed in the housing element;

    a second three-axis magnetic sensor device disposed in the housing element, wherein the second three-axis magnetic sensor device is positioned above the first three-axis magnetic sensor device in the housing element when the housing element is in a vertical orientation; and

    a circuit board module coupled to the first three-axis magnetic sensor device and the second three-axis magnetic sensor device, wherein the circuit board module is configured to compare output signals from the first three-axis magnetic sensor device and the second three-axis magnetic sensor device so as to determine a magnetic field distortion caused by a ferromagnetic object.
