Abstract

A sensor cable for surveying. The sensor cable may comprise at least one pair of current sensor electrodes and an amplifier. The current sensor electrodes may be disposed along opposite sides of the sensor cable. The current sensor electrodes may be configured to detect current in an electromagnetic field transverse to an inline direction of the sensor cable. The amplifier may be configured to amplify the current in the electromagnetic field for detection by the electrode pair.
