Innovative Laser Grade Technology
Four Robust Models Built for Accuracy, Simplicity and Productivity
Trimble’s innovative technology ensures higher accuracy than ever before over a variety of machine control and general construction applications. Plus, unique features help reduce beam drift errors and speed up setup and grade changing to optimise worker and machine productivity.
The Spectra Precision Laser GL700 Series from Trimble has four robust models, so you can select the right laser transmitter for the right application. Each model in the GL700 Series is designed to be simple to set up and use.
Ideal for site preparation, trenching and pipe laying, fine grading and road construction, the GL700 lasers can help you get to grade faster with more accuracy.
Models for Every Application
Select the Right GL700 Series Laser for Your Project
The GL700 Series offers four purpose-built grade laser models, each designed to meet the specific demands of different construction environments. From straightforward single-grade applications to steep slope work requiring extended grade ranges, there is a model suited to your operational requirements. All four models share the same commitment to ease of use, reliable accuracy and efficient setup, ensuring your team can get to grade quickly and confidently on any site.
GL710 Single Grade
An easy-to-learn, easy-to-use one-person grade laser, economical and accurate up to a 900 m diameter.
Ideal for general construction, site preparation, trenching and pipe laying applications.
GL720 Dual Grade
This economical choice has +/-10% in the X-axis grade range and -0.5 to +25% Y-axis grade range with high accuracy up to 900 m diameter. Ideal for general construction and machine control grade applications.
GL722 Dual Grade
With Long-range Radio Remote and with the same range and base capabilities as the GL720, the GL722 includes the benefits of the full Radio Remote functions… plus Automatic Axis Alignment capability. Ideal for general construction, site preparation and road construction.
GL742 Steep Grade
The GL742 includes all the features of the GL722 – including full Radio Remote – with the increased capability of achieving a steep grade range of 110%. Ideal for all general construction and machine control applications, as well as steep slope applications such as highway embankments, seawalls and landfills.
