Abstract: The invention provides in another aspect, an electric fence energiser for energising a first conductor which includes a purse generating circuit, at least one sensor means for detecting an electromagnetic field, which outputs a 5 signal based on the detected field, and a controller which analyses the signal to determine whether the field is caused by a pulse on a second conductor and, if so, to control the timing of pulses on the first conductor to be dependent on the timing of pulses on the second conductor.
