The method relates to a synchronization of a magnetic locating system including a first device and a second device each including an oscillator, a time counter clocked by the oscillator, and a radiocommunication module. The locating system also includes a device for emitting and receiving alternating magnetic fields, the device being configured to allow a propagation of alternating magnetic fields between the first and second devices, the device for emitting and receiving alternating magnetic fields being connected to the oscillators of the first and second devices. The synchronizing method includes a synchronizing step that is configured to synchronize the oscillators of the first and second devices by adjusting, by servo-controlling the oscillator of the second device, the operation of the time counter of the second device to the operation of the time counter of the first device.
