Frequently Asked Questions — Trimble SL700
What is the Trimble SL700 used for?
The SL700 is used for construction grade work with rotating lasers. It serves dual roles: as a field receiver on a grade rod for manual layout and as a machine control receiver mounted on dozer or grader blade masts. Its digital display shows exact elevation offset in millimeters or decimal feet, eliminating guesswork on cut/fill values.
How does the SL700 digital display work?
When paired with a compatible Trimble or Spectra Precision digital rotating laser, the SL700 shows the numeric cut/fill value directly on its LCD screen. Without a digital laser, it operates in passive mode showing only on-grade, high, and low indications via LED lights and audible tones.
What is the range of the Trimble SL700?
The SL700 detects laser signals up to 450m radius from the laser instrument. This is one of the longest detection ranges for a contractor field receiver, making it suitable for large earthmoving and site grading projects.
Is the SL700 compatible with non-Trimble lasers?
Yes. The SL700 detects any 635nm red-beam rotating laser in passive mode. Only Trimble and Spectra Precision digital lasers activate the full digital readout and machine control output features.
Can I use the SL700 on a machine dozer mast?
Yes. The SL700 includes both AA battery and 9–32VDC external power inputs. When mounted on a machine blade mast with external machine power, it provides continuous operation and sends digital control signals to compatible blade control boxes.
