military radio transmitters that use the VLF (Very Low Frequency) band, that is, 15 to 30 KHz commonly used for low distance communication. The WADI measures this field strength and phase displacement around a fracture zone or any conductive body in the rocks (Telford et al., 1990; ABEM 1990). It detects the ratio (in

The VLF receiver is specially designed for high productivity surveys, in ground water and mining exploration. No orientation of the operator with respect to the direction of the transmitter is required since three magnetic sensors measure the components of the VLF field. Tilt or horizontality of the sensor unit is neither required since two
