Spectra Precision LR60W-2 Laser Receiver with Radio
Product overview
The Spectra Precision LR60 Laser Machine Display Receiver is designed to be used as a stand-alone display receiver on grading and excavating equipment including dozers, excavators, backhoes, scrapers, and box blades. For excavators and backhoes, the LR60 laser receiver features patented Angle Compensation which automatically calculates and corrects the grade display for the angle of the dipper arm. The LR60W is designed to be used with the RD20 Wireless Remote Display.
The easy-to-use LR60 features versatile 360-degree laser reception and works with all types of rotating lasers on all types of machinery for fast, no-hassle setup. Rugged and waterproof, the LR60 receiver withstands all weather environments.
