The Magnetic Extensometer Anchor monitors changing subterranean displacements at various horizons within a borehole. There is no limit on the number of points that can be installed in one borehole. It can be extended and only one probe is required for many installations. The anchor measures soil and rock movements as well as subsidence, movement of natural and cut slopes, displacement of retaining walls, relaxation of rock around tunnels, etc.
