The Leica DISTO(tm) D2 laser distance meter combines practical functions in a simple and compact design. Specifically designed for indoor applications, it has shortcut keys for addition, subtraction, area and volume calculation which make measuring fast and very reliable. The functionality can be extended with the Leica DISTO(tm) sketch app. With this app you can transfer measuring results to smart phones or tablets, process and forward them. Prepare layouts and drawings, and dimension them precisely. In addition the Leica Disto D2 features stake out, last 10 measurement recall and Pythagoras functions which allow indirect measurements of height or width.
