Extend the BeamLRWs and RD20

The Spectra Precision® RD20 Wireless Remote Display is designed to be used with the LR30W, LR50W and LR60W display receivers. The RD20 mounts in the cab and gives the operator grade information in a convenient location. The operator is free to focus on the work at hand.

The portfolio starts with a simple receiver that can be used for small jobs over shorter distances and then moves into Laserometer technology that allows the user to get to the on-grade position faster and with less effort by displaying how far the receiver is from on-grade position in a graphical display.



Within the Laserometer range, Spectra Precision provides features that are tailored to use on any job site:

Anti-Strobe Filter – this patented design allows the receiver to be used on the busiest job site without interference from orange hazard warning lights on machinery.
Waterproof, dust proof and shockproof – can withstand a drop from 3m (10ft) onto concrete and can be immersed in water – allowing the receiver to be hosed down after a busy, dirty day on site.
Digital Read-Out – features a digital readout of elevation that provides a numeric display of +/- 5 cm (+/- 2 inches). The readout is displayed on the large front and rear LCD's and shows exactly how far the elevation is from on-grade. Accurate measurements can be made without moving the rod clamp, saving time and increasing productivity. Selectable units of measure can be displayed meeting your application - mm, cm, ft, in or fractional inches.


The Spectra Precision® DR400 DigiRod™ Digital Rod is a versatile, revolutionary tool that eliminates the need for grade rods when checking grades with a rotating laser. The combination of a laser receiver with digital readout, laser distance meter, and built-in tilt sensor provide the information required to take rod-less, accurate grade readings, even at tilt angles up to 30 degrees.
