The Spectra Precision GL1425C-2 is a professional dual-axis grade laser engineered for contractors who demand precise compound slope control on complex earthwork, grading, and drainage projects. Whether you're setting fall lines on a parking lot, establishing dual-pitch drainage, or aligning multi-axis site grades, the GL1425C-2 delivers the independent X and Y axis grade adjustment that demanding job sites require. This complete GL1425C-2 kit ships free and includes everything you need to work the day it arrives.
Product Overview & Jobsite Applications
The GL1425C transmitter projects a highly visible red laser reference plane across both horizontal and vertical axes, with independent dual-axis slope capability ranging from -10% to +10% on each axis simultaneously. The CR700 machine-mount receiver extends working range and integrates with machine control systems, while the RC1402N wireless remote lets one operator run the instrument from the cab or across the site. Built for outdoor use with IP66-rated weather resistance, the GL1425C-2 handles rain, dust, and rough handling common on active construction sites.

Job Applications
Parking Lot & Pavement Grading: Set compound cross-slopes and longitudinal grades simultaneously to meet ADA drainage and stormwater requirements without repositioning.
Agricultural & Land Drainage: Establish precision fall lines and cut grades across large open fields where dual-axis slope control eliminates multiple instrument setups.
Site Earthwork & Rough Grading: Mount the CR700 receiver on your blade or scraper for real-time grade feedback during cut-and-fill operations across the entire site.
Foundation & Slab Layout: Use the vertical beam plane for wall layout and column alignment while maintaining reference elevations for slab-on-grade pours.

Frequently Asked Questions
- Can the GL1425C-2 set two different grade percentages at the same time?
- Yes. The GL1425C features fully independent X-axis and Y-axis grade adjustment, each ranging from -10% to +10%. You can dial in a different slope on each axis simultaneously, making it ideal for compound drainage slopes, crowned surfaces, and multi-directional grade control without repositioning the instrument.
- What is the working range of the GL1425C-2 with the CR700 receiver?
- With the included CR700 receiver, the GL1425C-2 delivers a working diameter of up to 2,000 feet, making it well suited for large open sites. Indoor or obstructed environments will reduce effective range.
- Does the RC1402N remote control all instrument functions?
- The RC1402N wireless remote provides full control of grade settings, rotation speed, and power functions from up to approximately 1,000 feet away. This allows a single operator to adjust grades from a machine cab or across the site without returning to the instrument.
- Is the GL1425C-2 compatible with machine control systems?
- The CR700 receiver included in this kit is designed for machine mounting and integrates with grade control systems commonly used on motor graders, dozers, and scrapers. Check with your machine control manufacturer for specific compatibility with your existing system.
