With the magnetic mount, it can be easily attached to a backhoe, small excavator, box blade, or skid steer loader. The optional Spectra CR700 laser receiver can be rod or machine mounted, making it ideal for measuring cut and fill, leveling forms and footers, setting grade, and measuring elevation changes. ![]() Please select from the drop-down menu above. ![]() The Options with Receivers also come with a standard C70 Adapter Clamp. The Spectra GL412 Single Grade Laser w/ Vertical Alignment comes in variations that differ in the configuration of the package. This slope laser uses NiMH batteries and works up to 35 hours of continuous use. It can also withstand drops of up to three feet onto concrete and tripod tip-overs up to five feet. With an IP66 rating, the GL412N laser level is protected against dust and water jets from any angle. It also has a selection of sensitivity for accurate results even in high winds or on high vibration job sites. The Spectra GL412N has an out-of-level alert that shuts off the grade laser if it is knocked out of place to avoid erroneous readings. For anchor bolt and form alignment, itself-plumbs in the vertical position and can be mounted on a 5/8-11 tripod thread vertically or horizontally. The GL412N is also self-leveling horizontally and vertically within 5 degrees and has an accuracy of 1/16 inch per 100 feet. With a working range of up to 2,600 feet, it has a grade capability of 10 to +15 percent on a single axis. Rugged, accurate and easy to use, the CR600 provides high, low or on-grade information for all your grading and excavation applications.Simplifies level, grade, and vertical alignment setups, the Spectra Precision GL412N Single Grade Laser delivers reliable and accurate performance in various general construction applications. In addition to use as a handheld and rod-mounted receiver, the CR600 can be used as a machine control mounted receiver with 270-degree reception and a highly visible display for use on a backhoe, small excavator or skid steer. ![]() The highly visible LED display and dual sided LCD’s allow you to work anywhere.Īnother receiver option is the Spectra Precision Laser CR600 Receiver. The protective over molded housing withstands a drop of 3 m (10 ft) onto concrete. An anti-strobe sensor stops construction lights from setting off the receiver, and makes it easier to identify true laser beam signals. The large 127 mm (5 inch) reception height speeds up beam pickup in grade match and alignment applications. The HL700 features a digital readout of elevation that shows exactly how far you are from on-grade allowing quick elevation checks without moving the rod clamp. The Spectra Precision Laser HL700 Laserometer uses new technology to measure and display beam location and is ideal for use with the GL family of transmitters. Spectra Precision Laser HL700 Laserometer Use this versatile laser with a Spectra Precision Laser HL700 Laserometer at an operating diameter up to 800 m (2,600 ft), or use it with the CR600 machine-mounted laser receiver for fast and easy machine control display. The GL422 offers two additional advanced features: pointing mode for “Over the Top” pipe laying applications and grade match where the laser can be used to measure the existing grade value between two known elevation points. This capability eliminates interference with other crews on the job site by keeping the beam from straying into other work areas. On both models, the laser beam can be turned off electronically on up to 3 sides of your choice. Both units also incorporate automatic temperature and grade compensation for high accuracy in any weather or geographical location. Additionally, the GL412 and GL422 Grade Lasers self-plumb in the vertical position, to allow an even wider range of applications such as anchor bolt installation, plus form, tilt up and curtain wall plumbing. You can do everything with the remote control that you can do at the laser keypad, including grade reverse on both axes, up to 100 m (330 ft) away from the laser-even from the cab of the machine! The ability to make grade changes from anywhere on the job greatly reduces setup time and speeds operation, especially when multiple job grade breaks are needed. ![]() Both the GL412 and GL422 feature a 2-way, full- function remote control with a built-in back-lit grade display. And GL422 (dual grade) transmitters are cost- effective, automatic self-leveling lasers that do three jobs-level, grade and vertical alignment with plumb.
