Spectra Precision GL622N-14 Dual Grade Laser with CR700 Receiver

Versatile Automatic Single Grade Laser for Level, Grade, and Vertical Alignment

The GL622N is a dual slope grade laser. This rugged, automatic self-leveling laser has a grade capability of ± 25% and can be used in a wide variety of grading, excavating and alignment applications by general and specialty contractors. An intuitive keypad and graphic display mae all grade and alignment functions easy to use and greatly reduces setup time and increases productivity.

The GL622N includes the RC602N  full-function radio remote control. Both the remote and lasers  have  a large,  intuitive graphic displays and  keypads  that make  setups easier  and faster than ever. The displays are also backlit for ease of viewing. With the remote, contractors can do everything that they can do at the laser keypad, up to 500 feet away. The ability to make grade changes and start automatic alignments remotely can significantly reduce setup time and speed operations. 

Each laser system includes the advanced CR700 Digital Receiver that provides a digital readout of elevation and can be used at an operating diameter of up to 2,600 feet.  With the CR700, several advanced features of the GL622N can be utilized:

Grade Match:  Wireless communication between the CR700 Digital Receiver  and the transmitter provide automatic Grade Matching which allows measurement of unknown grade values between two points.

Plane-Lok: For applications that require maximum stability and accuracy, PlaneLok is available in both the horizontal and vertical planes. PlaneLok automatically locks the beam on the receiver and keeps it on grade, reducing typical environmental factors that may induce an error.

Automatic Axis Alignment (GL622N  only): Automatic axes alignments can be accomplished by positioning the receiver at the direction hub in a range of +/-40° at the desired laser axis. This allows contractors to easily perform dual axis alignments for grade work applications such as sports fields,  parking lots, tennis courts, driveways or any irregular field with non-perpendicular grade profiles
