Two new grade laser transmitters from Trimble have extended the capabilities of the GL700 series Spectra Precision Lasers. The Spectra Precision Laser GL742 offers a two-way remote plus a Y-axis grade range of 0 to 110 percent for accurate grading of steep slope projects such as retaining walls, dam embankments, environmental or waste dumpsite, and parking garages. The Spectra Precision laser GL642 puts a high accuracy model in the lineup for sites that need precision over longer distance ranges such as airport paving, longer-range roads, and large concrete construction sites.
