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 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. It also has highly visible LED display and features an anti-strobe sensor that stops construction lights from setting off the receiver and enables it to identify true laser beam signals. This laser receiver 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. The included HL700 Laserometer increases the GL422’s working diameter up to 2,600 feet. Featuring a sunshade with built-in scope mounting, this laser level allows you to easily install Spectra’s optional sighting scope for quick and accurate axis alignments over longer distances. You can also mount this device on a 5/8-11 tripod thread. Offering two additional advanced features, this Spectra rotary laser has a pointing mode that allows “over the top” pipe laying for house connections and grade match to measure existing grade value between two known elevation points. With a self-leveling accuracy of 1/16th inch per 100 feet, it is ideal for agricultural and construction applications. The GL422 grade laser has a dual grade capability of –10 to +15% on both axes and self-plumbs in the vertical position to allow bolt installation, form, tilt up, and curtain wall plumbing. This handheld construction laser also includes a HL700 laser receiver that features a digital readout of elevation and increases the GL422’s operating range up to 2,600 feet. 001% to 9.Overview for Spectra Precision GL422 Spectra GL422 Dual Grade LaserĬapable of self-leveling and plumb setup, the Spectra GL422 Dual Grade Laser offers additional features, such as pointing mode and grade match for pipe laying and highly accurate slope measurements. 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. The CR700 uses the patented “light bar” technology incorporated in the HL family of Spectra Precision laser receivers. Using the magnetic mount, the CR700 receiver is easily moved between backhoes, small excavators, box blades or skid steer loaders. The CR700 can be either rod or machine mounted, making it ideal for a wide range of applications. This strength, combined with full weatherproofing and dustproofing, reduces downtime and lowers repair costs over the life of the product.Įach GL412N and GL422N laser system now includes the advanced HL760 Digital Readout (DRO) receiver that provides automatic Grade Match - measures and displays the existing grade over unknown ground and eliminates time consuming and error prone calculations, and 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, and the unique "Fingerprint" function - receiver only accepts the beam from the laser it is paired with.Ģ-Way full fuction remote control allows grade changes to be made from anywhere on the job-site and has mask mode to eliminate interference from other crews running lasers on the job-site. The rugged GL412N/GL422N lasers can withstand drops of up to 1 meter (3 feet) onto concrete and tripod tipovers up to 1.5 meters (5 feet). Even in harsh jobsite conditions, the GL412N/GL422N delivers consistently reliable and accurate performance, enabling you to work faster and smarter. The automatic, self-leveling Spectra Precision® GL422-14N dual grade lasers are the most rugged, cost-effective lasers that do three jobs-level, grade, and vertical alignment. Versatile Automatic Grade Lasers for Level, Grade and Vertical Alignment
