The R20 range is composed of 3 versions, the R20 1000 m model with 2" angular accuracy, the R20 1000 m model with 1" angular accuracy and the R20 600 m model with 2" angular accuracy. The three models offer optimum performances up to 5000 m with prism and 1000 m or 600 m reflectorless The entire R20 range is equipped with a high performance, illuminated reticle telescope that provides the best quality of observation, whatever the environmental conditions. The programs on board of these models of total stations make them suitable for any work in construction, cadastral, mapping and staking, through a user friendly interface. Thanks to the presence of Bluetooth connection, it is possible to connect an external controller, giving the possibility to use a customized field software.
