Abstract

A lateral distance hand-held measuring device having a computer unit (2), an input/output unit (3) and a first laser distance measuring module (4a, 4b) transmitting a visible measurement laser beam (I, II). A second laser distance measuring module (4a, 4b) is provided, which transmits a second visible measurement laser beam (I, II) and is mechanically and data-technically coupled with the first laser distance measuring module (4a, 4b). The two measurement laser beams (I, II) have a defined pivot angle (α) relative to each other and known to the computer unit (2).
