The new, redesigned optic, is so bright that let you use the new STAL autolevels even in low-light conditions, thanks to the wide objective aperture (40 mm).
STAL 1100 are available with 28X and 32X telescope, and give accuracy from 2mm/Km to 1.5 mm/Km. STAL 1000, with the same telescope magnifications, thanks to the high accuracy automatic air damping compensator, features higher accuracy, up to 1.0 mm/Km on a double run leveling (STAL 1032). STAL 1100 offer minimum focusing down to 0.4 m for better performance in tight spots or on steep slopes.
