The Spectra Precision GL720 Dual Grade Laser with HL700 and CR600 Receivers provides long-range accuracy, dual-slope performance, and machine control capability. With an operating diameter of 3,000 ft (900 m) and grade range of -10% to +10% on the X-axis and -0.5% to +25% on the Y-axis, the GL720 is designed for applications requiring tight tolerances, including highways, landfill grading, airports, and large excavation sites. Automatic self-leveling and active temperature compensation ensure stable, repeatable results.
This bundle includes the HL700 Digital Receiver for grade checking with numeric readout, 15 accuracy levels, and rugged IP67 construction. It also adds the CR600 Combination Receiver, which works on both a rod and compact machinery like dozers, skid steers, and excavators. With bright LED indicators, 270° reception, and 3 m drop resistance, the CR600 enhances productivity and safety by allowing operators to check grade directly from the cab.
