The TL-80 emits a laser beam as reference axis. It is equipped with a horizontal and vertical rotation axis system with clamp and fine adjustment knob for quick and exact fine adjustment. The tunnelling laser can be used on its own or in combination with a traversing system. In this case it is advantegeous to adjust the trunnion axis height to the surveying instrument that is used.
