Spectra Precision LRWs and RD20 - "Extend the Beam"

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.

Tough, accurate and reliable sums up the Spectra Precision Laser receiver range. Spectra Precision has reputation for building high quality, robust receivers that incorporate patented technology to help you keep on working in the toughest job site conditions.
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.
