The accuracy of ± 1.5 mm on a base of 1 Km – double run – makes STONEX D1 the perfect equipment for the 3rd order leveling and for construction industry. Faster automatic measurements – difference in height and distance – are digitally determined: the fully electronic measurement results appear in the clearly visible display window after less than 2 seconds.
Stonex D2 digital level is the right solution to use when you need to measure gradients or height with better precision compared to GPS systems. GPS systems normally provide accurate measuring on plane (horizontal) but not in vertical direction, due to the position of satellites, all on the same side of sky compared to the GPS receiver
