Induced polarization is an effective method in exploration of nonferrous metals. Its efficiency is low while the working area including many IP profiles, which is a result of setting up a few of points in one section. In order to improve the efficiency of IP, a new remote electrode gradient device was created by using self-making multi-spacing central gradient device, which is based on Ge Weizhong’s gradient IP and remote electrode. This device can be used as Schlumberger electrode array in small polar distance and central gradient device in large polar distance. The efficiency of IP was improved by using remote electrode from traditional progressive arrangement to array arrangement. It shows the validity of using this IP device in survey of gold ore in complex tectonic and layers area.
