Spectra Precision GL612N Single Grade Laser Level

The Spectra Precision GL612N is a high-performance single-grade laser built for demanding construction tasks such as site prep, trenching, pipe installation, slope work, and general alignment. With a grade range of ±25% (manual, single axis) and accuracy of ±0.5 mm at 10 meters (1/16 inch at 100 feet), the GL612N offers precise control over elevation and slope. Its long-range capabilities extend up to 400 meters (1,300 feet) radius with a detector, and it supports rotation speeds of 300, 600, and 750 RPM.

The GL612N is engineered to withstand tough environments, with an IP67 rating for water and dust protection. It can operate in extreme temperatures from -20°C to +50°C (-4°F to 122°F). Powered by rechargeable 10Ah NiMH batteries or optional alkaline D-cells, it provides up to 35 hours of runtime, keeping your crew productive all day.

With built-in leveling indicators, LED feedback, and an LCD battery monitor, the GL612N helps reduce errors and streamline setup. It also includes the RC602N full-function remote control and HL760 digital readout receiver for enhanced grade matching and slope lock functionality.
