1. A system for detecting a buried conductor, the system comprising:
- means for producing an alternating test current in said buried conductor;
means for detecting an electromagnetic field produced by the test current in said buried conductor; and
means for providing a communication link between the means for producing an alternating test current and the means for detecting an elecromagnetic field;
wherein the means for producing an alternating test current and the means for detecting an electromagnetic field are configured for the means for detecting an electromagnetic field to set, via the communication link, characteristics of the test current produced by the means for producing an alternating test current in response to the electromagnetic field detected at the means for detecting an electromagnetic field without intervention from an operator of the system.

Abstract
A system for detecting a buried conductor comprises a transmitter for producing an alternating test current in the buried conductor and a receiver for detecting an electromagnetic field produced by the test current in the buried conductor. A communication link is provided between the receiver and the transmitter. The receiver measures the signal to noise ratio, SNR, of the electromagnetic field produced by the test current and if the SNR is below a threshold then the receiver controls the transmitter to set frequency and/or power characteristics of the test current.
