The automatic self-leveling Spectra Precision® GL1425C dual grade laser is the most rugged, cost-effective laser that does three jobs—level, grade, and vertical alignment. Even in harsh jobsite conditions, the GL1425C delivers consistently reliable and accurate performance, enabling you to work faster and smarter.
The GL1425C has Bluetooth built in so it can work with the Spectra Precision Laser Remote App and
eliminate the cost of the remote control. The laser can be controlled with your smartphone.
The rugged GL1425C laser can withstand drops of up to 1 meter (3 feet) onto concrete and tripod tip overs up to 1.5 meters (5 feet). This strength, combined with full weatherproofing and dustproofing, reduces downtime and lowers repair costs over the life of the product.
The GL1425C has options for receivers. The advanced HL760 Digital Readout receiver provides
automatic Grade Match which allows measurement of unknown grade values between two points over unknown ground and eliminates time consuming slope calculations. PlaneLok automatically locks on to an existing elevation or vertical alignment point which eliminates all drift or possibility of error due to improper calibration or weather. The CR700 receiver is also an option when a machine mounted display elevation is required.

The Spectra Precision® CR700 Combination Laser Receiver is a machine mounted display receiver used on small grading and excavating equipment as well as a traditional laser receiver mounted to a grade rod. The CR700 includes both a magnetic mount for quick machine mounting and a grade rod clamp.
 
With super bright directional LEDs, the CR700 is ideal for entry-level machine grade display, specifically on mini-excavators and backhoes. This provides instant grade information to the operator and eliminates the need for a rod man in the trench. 
 
The CR700 uses the patented “light bar” technology incorporated in the HL family of Spectra Precision laser receivers. This unique technology provides more accurate and more consistent readings than traditional methods and has fewer electronic components resulting in the most rugged and reliable laser receivers available.
 
It is also ideally suited to work in vertical application for alignments control. The LEDs are visible at long range and a vertical drift alarm warns if the laser is disturbed.
 
Features and Benefits
