Increase your profits with the Spectra LR20 Laser Receiver
The LR20 Laser Receiver is Spectra Precision’s basic machine-based laser receiver. When used with your grade laser, this device allows machine operators to quickly determine whether a grade needs to be raised or lowered without having to rely on a rodman. This saves equipment hours as well as man-hours. It also speeds up all parts of a grading or leveling operation, keeping projects on schedule and under budget.

- Grading and excavation
- Site preparation
- Road, runway, and landfill construction
- Agricultural land levelling and drainage
- Laser based machine control
