Spectra Precision GL1425C-16 Dual Grade Laser Package, Bluetooth w/ Deluxe CR700 Multi-Use Receiver, Tripod and Rod TENTHS

The Spectra Precision GL1425C-16 is a professional dual grade laser system engineered for contractors who need precise simultaneous slope control in two axes. Whether you're grading a parking lot with cross-fall requirements, designing drainage channels with compound slopes, or managing complex site development, the GL1425C-16 delivers the accuracy and connectivity to get the job done right. This complete kit includes the GL1425C laser, CR700 multi-use receiver, grade rod, and tripod — everything your crew needs to hit the ground running.

System Overview & Jobsite Applications

The GL1425C-16 is built around a self-leveling dual grade platform that sets independent slopes on both the X and Y axes simultaneously, eliminating the limitations of single-grade lasers on complex terrain. With a working range of up to 2,000 feet in diameter and a grade range of ±10% on both axes, this laser covers the full spectrum of commercial and civil grading demands. The integrated Bluetooth module allows wireless grade adjustments directly from the CR700 receiver, reducing trips back to the instrument and keeping your crew productive. The rugged housing is dust- and water-resistant, built to survive real-world jobsite conditions across extended shifts.

Job Applications

Parking Lot Grading: Set precise cross-fall and longitudinal slopes simultaneously to meet ADA and stormwater drainage requirements without resetting the instrument between passes.

Drainage Channel Construction: Dial in compound slopes for swales, retention basins, and detention ponds where water must flow accurately in two directions at specified grades.

Site Development & Rough Grading: Control cut-and-fill operations across large commercial sites with consistent dual-axis elevation references that keep machine operators on grade all day.

Asphalt & Concrete Paving: Provide screed and paver operators with a reliable dual-slope reference plane for superelevation, crowned roadways, and sloped flatwork pours.

Frequently Asked Questions

What is the difference between the GL1425C and a single-grade laser?

A single-grade laser sets slope in only one direction at a time. The GL1425C sets independent grade values on both the X and Y axes simultaneously, making it essential for parking lots, drainage systems, and any application requiring compound or dual-directional slopes.

Can I control the GL1425C remotely from the receiver?

Yes. The GL1425C uses Bluetooth connectivity that pairs with the included CR700 receiver, allowing the rod person to adjust grade settings wirelessly from up to 300 feet away without walking back to the laser head.

Is the CR700 receiver compatible with other Spectra lasers?

The CR700 is a multi-use receiver compatible with a range of Spectra Precision rotating lasers. Check the compatibility list or contact Express Tools to confirm fitment with your existing equipment.

How long does the rechargeable battery last in the field?

Under typical operating conditions, the GL1425C battery pack provides up to 55 hours of runtime on a full charge, easily covering multi-day use between charges on most jobsites.
