Using the magnetic mount, this machine control receiver can be easily attached to a backhoe, small excavator, box blade, or skid steer loader.Īnother optional receiver is the Spectra HL760 which features a digital readout of elevation and unique fingerprint function, This laser receiver also provides automatic grade matching and PlaneLok to eliminate manual slope adjustments and errors due to improper calibration or weather. The optional Spectra CR700 is ideal for measuring cut and fill, leveling forms and footers, setting grade, and measuring elevation changes. 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, this laser level is dustproof and can be used in heavy rain. It also has a selection of sensitivity for accurate results even in high winds or on high vibration job sites. The Spectra GL422N has an out-of-level alert that shuts off the grade laser if it is knocked out of place to prevent inaccurate readings. For anchor bolt and form alignment, it self-plumbs in the vertical position and can be mounted on a 5/8-11 tripod thread vertically or horizontally. The GL422N is also self-leveling horizontally and vertically within ±5 degrees and has an accuracy of ☑/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 both axes. This ruggedized, automatic slope laser provides contractors with accurate leveling, grade, and vertical alignment. The Spectra Precision GL422N Dual Grade Laser was designed for a wide range of general construction, site preparation, and excavations. This Spectra grade laser package comes with a HL700 laser receiver, remote control, rod clamp, carrying case, NiMH rechargeable battery pack, charger, AA alkaline batteries and a 5-year manufacturer’s warranty.Overview for Spectra Precision GL422N-BCC GL422N Dual Grade Laser With Vertical Alignment With an IP66 rating, the GL412 laser level is protected against dust and water jets from any angle and can survive drops of up to three feet high on concrete! This grade slope laser uses four NiMH batteries and works up to 55 hours. It also includes a RC402 radio remote control that gives you full control of the laser from up to 330 feet away. Incorporating automatic temperature and grade compensation, this Spectra laser level delivers highly accurate results in any weather or geographical location. It also features an electronic leveling vibration filter that dampens vibrations typically experienced on tall tripods, in high winds or on high vibration worksites. The Spectra Precision GL412 has a mask mode that allows you to turn the laser beam off electronically on up to 3 sides of your choice to eliminate interference with other crews. It also has a capture function that remotely captures and retains a measurement when the display is difficult to see. Excavation mode puts more reception height and elevation information above grade for higher utilization in digging and staking applications. With a large five-inch reception height, the handheld or rod mounted Spectra HL700 laser detector acquires the beam quickly and makes it easy to stay in the beam. The readout is displayed on dual sided LCDs and selectable units of measure are displayed in millimeter, centimeter, feet, inches or fractional inches. Increasing Spectra GL412’s working diameter up to 2,000 feet, this laser receiver has highly visible LED display and features an anti-strobe sensor that stops construction lights from setting off the receiver and makes it easier to identify true laser beam signals. The included HL700 Laserometer provides digital readout of elevation that shows exactly how far you are from on-grade and allowing quick elevation checks without moving the rod clamp. You can also mount this rotary laser on a 5/8-11 tripod thread vertically or horizontally. Featuring a sunshade with built-in scope mounting, you can easily install Spectra’s optional sighting scope for quick and accurate axis alignments over longer distances. It is ideal for agricultural and construction applications with its self-leveling accuracy of 1/16th inch per 100 feet. With grade capability of –10 to +15% on a single axis, the GL412 grade laser self-plumbs in the vertical position to allow bolt installation, form, tilt up, and curtain wall plumbing. This construction rotary laser has a 2,000 foot range and includes an HL700 laser receiver that features a digital readout of elevation and increases the GL412’s operating range up to 2,000 feet. The Spectra GL412 Grade Laser is a rugged, automatic self-leveling laser that performs level, grade and vertical alignment. Overview for Spectra Precision GL412 Spectra GL412 Grade Laser
