High Accuracy
±0.1mm/m grade accuracy — holds tolerance through a full working day.
Continuous grade control. No continuous labor.
Grade stakers cost $50–80/hr and disappear between passes. A dual-slope grade laser installs once and controls your blade automatically — through every cut, every fill, every pass. That's the math that makes grade lasers one of the fastest ROI investments in earthwork.
Professional contractors specify dual-grade systems for a reason: single-grade units work for straight drainage. The moment a job has a crown, a swale, or a complex parking lot slope — you need dual-grade.
Buying from Express Tools means authorized, factory-fresh inventory, legitimate firmware, and technical knowledge when you need it.
