The Spectra Precision GL1425C represents the newest generation of dual grade laser technology, combining speed, ruggedness, and precision in a platform engineered for demanding construction site conditions. With grade range capability of ±9% without adjustment and ±15% with tilt, the GL1425C accommodates slope work from gentle grades to challenging hillside applications. Triple-duty functionality—leveling, grade, and vertical alignment—means a single instrument handles diverse site tasks, reducing equipment logistics and setup time on complex projects.
Rotation speeds of 300, 600, and 900 RPM provide operators flexibility to match coverage area and application requirements. Higher speeds deliver faster area coverage for large site preparation and general grading work, while lower speeds ensure precision in finishing grades and critical elevation control points. The 800-meter range with HL760 receiver enables operation across large construction sites without frequent instrument repositioning, improving crew efficiency and maintaining consistent elevation control across extended work areas.
Accuracy of 1.5mm at 30 meters ensures the GL1425C meets or exceeds specifications for site grading, foundation preparation, and finish work where elevation tolerance is critical. This precision capability supports modern construction sequencing that demands repeatable, verifiable elevation control across multiple trades and project phases. The laser's consistency enables contractors to maintain specifications efficiently, reducing rework and material waste associated with grade variation.
Durability is built into the GL1425C's design. IP66 rating ensures water and dust protection through active job sites and variable weather conditions. The instrument survives 1-meter drop impact—typical of site environment reality—without recalibration, protecting contractor investment and minimizing downtime from equipment damage. The 45-hour NiMH battery provides extended operational range on multi-day project phases, while Bluetooth connectivity enables wireless remote operation, improving operator safety and line-of-sight flexibility on active sites.
Built-in Bluetooth and Laser Remote App compatibility modernize grade control workflow. Operators control laser functions wirelessly from grade rod position, improving visibility and safety by eliminating need to run back to instruments for adjustments. This connectivity accelerates site setup and reduces cycle time for grade verification and correction across large areas.
