The Root Detector is designed for determining the location of the roots of a selected tree. It works based on sound velocity measurements between a sensor attached to the trunk and a soil sensor placed close to the root. Adjusting the position of the soil sensor while keeping a fix distance from the tree enables us to map the entire root structure. The benefit of this method is that the measurement is not disturbed by other trees' roots, pipes or other buried materials.
