Depending on the operators ability, grading by sight, strings, or hubs cannot match the continuous sweeping accuracy of the fully automatic LASER-TECH- Machine Control System. Skilled operators are in short supply. LASER-TECH Machine Control Systems help fill that void, providing novice operators the ability to control grade within a few hundredths of a foot and making the skilled operators job easier and faster. Surveying and materials costs are lowered; no stakes or hubs to pound; no waiting for grades to be checked. Costly errors are reduced - Job quality is increased and when the job is finished, it's correct!
