Rugged – the GL622N and GL622IR can withstand a 1m (3 feet) drop directly onto concrete or 1.5m (5 feet) pushover on tripod, eliminating costly repairs. Grade Range – Large, fully compensated grade range from -25% to 25% – keeping the laser levelled no matter what grade you need reducing errors and improving productivity.Īnti-Vibration Filter – A laser can be affected high vibration or strong wind, especially when the laser is mounted on a tall tripod –both the GL612N, GL622IR,Īnd G622N have an anti-vibration filter that can be set according to the conditions allowing work to continue regardless of wind conditions or excessive vibrations. Long Range – one person elevation and grade control with 800 m (2,600 ft) diameter range increases productivityĪutomatic self-levelling – provides fast, easy set-up for horizontal level, grade or vertical alignment (vertical on GL622N only)Īutomatic Grade Matching – meaning the laser moves to the on-grade position on the receiver automatically by communicating wirelessly with the receiver and the grade is then calculated – this is generally used when a constant fall is desired but the grade may not be known (renewing existing driveways or matching existing surfaces) The GL622IR is not used for vertical alignment or 90 degree layout. Been way more handy than I ever would have imagined.Multiple Applications – the Spectra Precision GL622N provides the ability to control level, alignment, dual grade and set 90 degrees. Oh, and I would never buy a laser without a remote again. Like Shimmy1, I am a fan of the CR600 receiver, and keep one of these in the laser case for everyday use. ![]() Haven't done it yet, but many times I have had grade checkers that have trouble communicating what is going on and seem to always have the receiver turned away where I cannot see it. I always thought the dual linked receiver thing would be cool to have one receiver in the cab, displaying what the grade checker was seeing with his receiver. I have used the 522 as my daily laser ever since with no complaints. I don't think these are as stable as their more expensive cousins, like the 722. ![]() Every morning I would set up the laser and the alignment receiver on their fixed mounts, set the other receiver that I held in my hand to display the fixed one (since I could hardly see it at this distance), then rotated the laser as necessary to get and on grade reading Worked slick, the only thing I noticed was at a few hundred feet, the laser would sometimes drift up and down maybe as much as a half an inch during the day. ![]() I set up a fixed mount for the laser and a fixed mount for one receiver (for aligning the laser), both on the structural steel of the building and a couple of hundred feet apart. These receivers can talk to each other so one can display the reading of the other. I purchased a Gl522 kit with a remote and two HL750 receivers. A few years ago I had a job where I needed to set up a 80,000 square foot pad with dual slope and repeat it every day for a couple of months for all the other subcontractors.
