1. A locator for locating a buried electromagnetic marker, the locator comprising:

  • a transmission antenna for generating a first oscillatory magnetic field to couple with an electromagnetic marker; and

    a first reception antenna for receiving an oscillatory magnetic field emitted by the electromagnetic marker,the transmission antenna being configured to generate a test oscillatory magnetic field,the first reception antenna being configured to receive the test oscillatory magnetic field and thereby generate a first detected test signal,the locator further comprising a first analogue to digital converter configured to generate a first digitised test signal from the first detected test signal, the first digitised test signal being indicative of the test oscillatory magnetic field received by the first reception antenna.
