Leica Geosystems’ Leica Sprinter 50 one-button electronic digital level is suitable for daily tasks on construction sites. Users aim, focus on the bar code staff, and measure by single button press. Data, accurate to 2 mm (0.08 in) deviation per 1 km (0.6 mi) double run, is displayed digitally on a large LCD, and built-in tilt sensor prevents the system from measuring outside the compensator range. For more complex leveling tasks, the Sprinter 150/150M and 250M family feature built-in data storage to store up to 1000 downloadable and transferable measurements. And according to the company, the Sprinter 150 automatically determines delta height and other functions.
