This past winter vacation, my family and I decided to take up skiing. None of us had ever gone before and we were all very excited for the experience. When my family arrived at the Ski Resort we dumped our luggage in our rooms and grabbed the new gear we just bought. We ran outside and looked out at the huge mountain with people skiing downhill. There was some shared disappointment when we realized that we had to start at the beginners slope before we could try anything else.
My family rushed to the beginners slope to receive instruction on how to ski properly and to start practicing. The beginners “slope” look more like flat land then a hill. I wondered briefly whether we would actually be able to ski down it or whether it was only to practice standing. However, when I tried to ski I found that the beginner’s hill was indeed sloped. I recognized that it must be sloped at a very slight angle or at a 5-10% slope. The only way the Ski resort could have achieved a perfect slope like that was by using a Spectra Precision GL512 or GL522 Grade Laser.
The Spectra Precision GL512 or GL522 Lasers are rugged, cost-effective, automatic self leveling lasers that do three jobs—level, grade and vertical alignment. The difference between the GL512 and the GL522 grade laser is that the GL512 is a single slope and the GL522 is a dual slope laser. This means that the GL512 can only slope in one axis while the GL522 can slope in both. Both lasers have a large grade range from -10% to +15%.
Both the GL512 and the GL522 include a two-way remote control with a built in back-lit display. You can do everything with the remote control that you can do with the laser keypad for up to 330 feet away from the laser! The ability to make grade changes from anywhere on the job greatly reduces setup time and speeds up the operation.
Additionally, the Spectra Precision GL512 and GL522 Grade Laser self-plumb in the vertical position to allow an even wider range of applications such as tilt up and curtain wall plumbing, anchor bolt installations and plus form. Both units also incorporate automatic temperature and grade compensation for high accuracy in any weather or geographical locations. The Electronic Leveling Vibration Filter on the Spectra Lasers dampen vibrations typically experienced on tall tripods, in high winds, or on high vibration jobsites. On both models, the laser beam can be turned off electronically on up to three sides of your choice. This capability eliminates interference with other crews on the job site by keeping the beam from straying into other work areas.
New wireless communication between the HL750 Receiver and the Spectra Precision GL512/GL522 laser provides automatic Grade Match. Grade Matching allows the measurement of unknown grade values between two points. Grade Match displays the existing grade over unknown ground and eliminates time consuming, error prone calculations, time spent searching for grade plans, and over excavating. PlaneLok is also available in both the horizontal and vertical planes. PlaneLok automatically locks the beam on the receiver and keeps it on grade. This eliminates all environmental factors that may induce an error. Furthermore, the HL750 Receiver works with a second HL750 for long range wireless remote display and monitoring.
The Spectra GL512 and GL522 Grade Lasers are great for general construction leveling such as forms, footers and pads. They also provide precision placement of concrete for critical specification surfaces over long distance. The GL512 and GL522 can also be used for sports fields, driveways, ramps and drainage, steep slopes, road embankments, ditch banks, parking garage, mini-mart, tennis courts, golf course and of course ski slopes!
