The Spectra Precision GL1425C Dual Grade Laser is a rugged, high-accuracy grade laser designed for earthmoving, excavation, drainage, site preparation and general construction applications.

Providing dual-axis grade control of up to ±15% with tilt adjustment, the GL1425C allows operators to establish accurate slopes across both axes, making it particularly useful for grading, ramps, drainage works, road construction and other applications where precise elevation and slope control are required.

This package includes the GL1425C laser and RC1402 remote control but does not include a laser receiver, making it ideal for contractors who already own a compatible receiver or want to select a receiver separately.

Accurate Dual Grade Control

The GL1425C combines automatic self-levelling with precise dual-grade capability for faster and more reliable site setup.

Key features include:

• Dual-axis grade capability up to ±15% with tilt adjustment
• Typical ±9% grade range without tilt adjustment
• Horizontal and vertical levelling accuracy of ±1.5 mm at 30 m
• Automatic self-levelling
• Rotation speeds of 300, 600 and 900 RPM
• Height of Instrument alert to help prevent incorrect readings if the laser is disturbed
• Bluetooth connectivity for control through compatible Spectra Precision remote-control functionality

Built for Large Construction Sites

When paired with a compatible laser receiver such as the Spectra HL760, the GL1425C provides a working diameter of up to 800 metres, giving contractors the range needed for larger civil, earthmoving and construction projects.

The included RC1402 remote control provides radio operation from up to 100 metres under suitable conditions, allowing adjustments to be made without repeatedly returning to the laser.

Rugged Jobsite Performance

Designed for demanding construction environments, the GL1425C features an IP66-rated enclosure for protection against dust and water.

The laser is engineered to withstand a drop of up to 1 metre onto concrete and uses a rechargeable 10,000 mAh NiMH battery pack, providing approximately 45 hours of operating time under typical conditions.
