The Spectra Precision LR50 Laser Machine Display Receiver is built for accurate grading and excavating on dozers, excavators, backhoes, scrapers, and box blades. Its large detection window and bright LED indicators make grade information easy to read, even in tough jobsite conditions. The built-in blade tilt indicator helps operators maintain a level blade for increased accuracy and efficiency, while the center on-grade mode delivers equal grade information above and below on-grade for balanced operation. For excavation work, the built-in plumb indicator enables fast, precise grade checking, and the offset on-grade mode maximizes the use of the receiver for productive digging.

Also available in a wireless configuration as the LR50W for cable-free operation.
