Spectra Precision RD20 Wireless Remote Display for LR30W LR50W LR60W Machine Control Receivers – in-Cab Grade Indicator with IP67 Rugged Housing

The Spectra Precision RD20 Wireless Remote Display is engineered for professional machine control and surveying applications offering in-cab visibility of grade data from compatible display-receiver systems such as LR30W, LR50W and LR60W. It delivers wireless communication capabilities that extend up to approximately 100 feet under ideal conditions, enabling operators to monitor grading, slope or elevation indicators from inside the cab without leaving the machine. The unit features ultra-bright tri-color LED indicators. With red for high, green for on-grade, and blue for low, which remain clearly visible even in bright sunlight or peripheral vision. An integrated speaker provides audible tones up to 105 dBA (adjustable levels) for operators who prefer or require non-visual alerts in noisy or dusty job-site environments. The housing meets an IP67 rating for dust and water ingress protection, and the module is ruggedized for vibration-intensive environments. Power options include internal AA batteries for mobile usage and external machine power input (10-30 V) with automatic switchover, ensuring uptime regardless of whether the display is used on a skid steer, excavator, dozer, or other heavy-duty equipment. The mount system is versatile: a quick-disconnect plate, suction cup, or magnetic base plus double-sided adhesive provides flexible installation across vehicle types. Whether you are performing trenching, site prep, fine grading, or mining work, the RD20 Remote Display supports improved productivity by reducing operator movement and enhancing situational awareness with real-time grade feedback. For any fleet using compatible Spectra Precision wireless receiver systems, this display is a high-value extension that will help streamline your workflow.
