S-field is sophisticated technology in resistivity meter. It is state-of-the-art multi-channel portable memory earth resistsivity meter with memory storage of readings and user defined measure cycles. It provides the highest accuracy and lowest noise levels in the industry. This new instrument revolutionizes the field of resistivity imaging surveys by its capability to simultaneously measure upgradeable 16, 32, 64 max 1000 channels using a high power transmitter so that field data production can reach previously unheard of speeds. With this instrument it is now possible to efficiently record 2D and 3D resistivity data
