Bi Reflex Targets

Also known as "GEODETIC TARGET/ SURVEY MARKERS". These targets are extensively used for the measurement of deformation during (a) Tunneling (2) During sub way construction, and also for monitoring displacement/deformation in 3-directions of a Bridge/ Dam/Slope, and a building structure on the top of the "Tunnel alignment", and for the building/structures in Zone-of-Influence.  Bi-rfelex targets consists of reflectors on both sides is mounted on a universal joint. The target has a small hole at the center to allow precise targeting. It works very well in a Measuring range from: 12 m to 140 meters. Measurements are made by a Total station/Theodolite.
