The Leica CS20 controller offers a robust design and improved ergonomics as well as a 5″ WVGA touch screen ensuring maximum visibility even in the sun. The Captivate software provides an intuitive interface for the first time merging the overlay of measured points, 3D models and point clouds into a single view. The basic Leica Viva CS20 controller is the most economical option whereas the 4G et 4G DISTO^TM models are more versatile and let you control a robotic total station. Moreover, the Leica Viva CS20 4G DISTO^TM is designed to evolve and meet the latest technological advances (compass, gyroscope, accelerometer, telemeter, etc.).
