Michael Willhite owner of Willhite Grading & Excavation demonstrates a quick way to set grade using the Trimble LR50W receiver and magnetic mount. This mount can entirely cut out a need for ground man grade checking during bulk out finish grading or even footing excavations leaving your ground man to attend to other work and cutting labor out of your budget.
The Trimble LR50W can also be used as a blade receiver mounted single mast center blade or duel mast running two receivers. This system is a great affordable entry tool into the high tech world of laser and 3D systems.
