Product Description

The Spectra Precision GL1425C Dual Grade Laser is designed for high-accuracy grading, excavation, and alignment tasks. With an operating range of up to 2,600 ft (800 m) in diameter and accuracy of 1/16 in at 100 ft, it ensures precise results across large sites. The laser offers 15% dual grade capability, self-leveling, and rotation speeds up to 900 rpm, making it suitable for slopes, formwork, sports fields, and complex construction layouts.

The GL1425C is backed by an IP66 dust and water rating and survives drops up to 1 m onto concrete. Integrated Bluetooth allows operators to control all functions via the Spectra Laser Remote App, eliminating the need for a separate remote. Advanced features like Automatic Grade Match and PlaneLok minimize slope calculation errors and prevent alignment drift.
