The Geohm System belongs to the geo-electrical family of prospecting devices, and is a system for substratum exploration by electrically scanning along lines of preplanted sensors. The system generates a horizontal section of the values of resistivity in archaeological sites. The Geohm is an uncomplicated system comprising of a portable computer, an analogical-digital conversion device, a multi relay switcher (software controlled), a solid state current converter (also software controlled), and a lot of moving sensors inserted in the ground. The measured groups of returned signals are processed by complex algorithms before the data is validated: this technique makes it possible to obtain more reliable measurements and allows the user to reprogram the device. The speed of the system allows the user to survey a large area using several electrical devices.
