about us

TBM Guidance Systems – Made in Bavaria

Since 1993 we have developed and supplied laser-based guidance systems for tunnel boring machines. From our company’s location in Munich (Capital of the Free State of Bavaria) we have successfully completed well over one hundred projects worldwide. All our products are developed and manufactured in Munich, Germany.


Our solutions are suitable for all tunnel diameters and ground conditions. Our target units (Video Target) are sized to suit the TBM diameter. (see products). They are used on any TBM machine type including EPB, double shield or main beam machines.
