and trenchers. Five channels of grade information plus directional out-ofbeam indicators. Three
selectable accuracies meets job tolerances from rough grading to final finishing.

Grading and excavating display receiver.
 5 channel display - easier to find on-grade
 3 deadband setting to optimize accuracy v speed requirements
 2 Brightness settings to optimize visibility and reduced eye strain
 7" photocell height for large laser reception

LR50 GRADE DISPLAY RECEIVER
Built-in blade tilt indication helps the operator keep the blade level for increased production and accuracy. Can be programmed
to match an existing or known grade for slope matching operations. Center On-grade provides an equal amount of grade information
above and below on-grade. Use on dozers, graders, scrapers, and box blades. Built-in plumb indication for quick and accurate
grade checking for backhoes and excavators. Offset On-grade provides more information above grade using the entire receiver for
productive excavation. Up to six channels of grade information plus directional out-of-beam indicators. Three selectable accuracies
for each ongrade location. Use as a stand-alone display receiver or combine with the CB25 control box to create affordable
automatic blade control for dozers.

The robust Trimble LR400 receiver combined with the GL700 transmitter is designed specifically for earthmoving applications performed with larger machines like dozers, scrapers and excavators. The receiver features center on-grade for use with dozers and scrapers and an "excavator mode" for use with excavators and backhoes. Using the excavator mode, more above-grade information is displayed making it easier for the operator to lower the bucket and cut to the correct grade.

Features & Benefits

• Large LED display arrows indicate "high" or "low" with amber lights and "on-grade" with green lights so the operator can quickly and easily move the cutting edge to a desired elevation, especially on larger machines such as excavators, dozers and scrapers, for improved productivity.
• Adjustable accuracy bandwidths and distinct modes for specific applications and equipment provide flexibility to meet the machine needs and the accuracy requirements of the job.
• Selectable "on-grade" location and accuracy indicators provide improved efficiency and allow customization of the receiver to each unique application.
• Rugged, waterproof magnesium housing withstands tough jobsite conditions.
• Powered using its own battery or using the machine's battery.

Spectra Prince Albert 360° Receiver detects and provides 5 or 7 channels of grade information, with vertical sensing range of 7.3", mounts on tubing from 1 1/2" to 2" dia.
