Spectra GL1425C Dual Grade Laser Level

Spectra Precision GL1425C Dual Grade Laser & HL760 Digital Receiver

Fully Automatic Self‑Levelling

The GL1425C handles automatic self‑levelling in both horizontal and vertical modes. Once powered on, it quickly finds level, and if the instrument is disturbed, the beam shuts off and the HI (Height of Instrument) alert activates. This prevents grade errors and ensures consistent accuracy throughout the job.

Long‑Range, High‑Accuracy Grade Control

Designed for demanding civil and construction applications, the GL1425C delivers a working diameter of up to 800 meters with the appropriate receiver. Its precision makes it ideal for roadwork, drainage, foundations, and large‑scale site preparation.

Dual‑Axis Grade Capability

Unlike basic rotary lasers, the GL1425C provides fully automatic grade control on both axes. This allows operators to input precise slopes for driveways, car parks, sports fields, access roads, and engineered drainage systems. Grades can be set digitally for repeatable, reliable results.

Digital Receiver Compatibility

The GL1425C is typically paired with the HL760 digital receiver. This provides a clear numeric readout of elevation, eliminating the need to manually “find on‑grade.” The receiver displays exactly how far you are from level in millimetres or inches, dramatically speeding up grade checks and reducing rework. With built‑in Bluetooth and the dedicated Laser Remote App, operators can control key functions from their phone for easier, smarter setup.  making it ideal for drainage, roadwork, foundations, and large‑scale construction.

Built for the Jobsite

IP66 Environmental Protection

The GL1425C is fully dustproof and protected against powerful water jets, ensuring dependable performance in heavy rain, mud, and harsh outdoor environments.

Drop and Tip‑Over Protection

Engineered for real‑world durability, the GL1425C is rated to survive a 1‑meter drop onto concrete and a 1.5‑meter tripod tip‑over. It’s built to keep working even when the site gets rough.

Reinforced Optics and Housing

The rotating head is protected by a metal sunshade and thick glass lens, shielding the optics from wind‑blown debris, accidental knocks, and jobsite dust. This ensures a clean, consistent beam even in challenging conditions.
