Trimble® offers a laser receiver, grade lasers, a sonic tracer and laser receiver mast to help enhance and extend the abilities of your 2D grade control system.

LR410 Laser Receiver

Mounted to an electric mast on the blade, the LR410 laser receiver is connected to your machine’s hydraulics to control lift to an accuracy of 3 to 6 millimeters.

GL700 Series Grade Lasers

Get years of durable, precise machine guidance with your GCS900 2D or GCSFlex™ grade control  system as well as laser-based compact machine installations with the Spectra Precision® Laser GL722 or GL762 grade laser. The GL700 series of lasers are ideal for site preparation, trenching and pipe laying as well as fine grading and road construction. Whatever the application, the GL700 series of lasers will help you get to grade faster and with more accuracy.

 ST400 Sonic Tracer

Mounted to the blade, the ST400 sonic tracer uses a physical reference such as a curb or gutter, stringline, or an existing or previous pass as an elevation reference.

SR300 Laser Receiver Mast

Mounted to the blade, the SR300 laser receiver mast is used with a GL series grade laser or can be upgraded with a Trimble GNSS Smart Antenna for blade control to 3 to 6 millimeters.
