I bought this laser to do a project on my property. I am 71 years old and decided to make a circular driveway and a patio and a barn on my property. After 50 years of being self employed I retired from trucking and towing and called some people out to build this project. Was quoted over$150,000.00. I decided to buy the tools and do it myself. So I bought a new tractor and the tools to start the process and now 6 months later I am almost finished with the driveway and the patio. I had to use the laser to level and pull everything to grade. The driveway is 280’by 28’ the new front walkway and the new front entrance also required the laser as it took over 18 yards of concrete. The driveway has 60 yards. And I had to move and replace over 800 yards of dirt and replace a lot of that with road base. Not to mention the 700’of retaining wall that had to be built. Put in the pipe for drainage. Now in the back of the house I had to cut the area to put in the retaining walls. All the footings had to be level and with out the laser I could have never done it. The patio is 43’ by 61’and it looks gorgeous. Drainage is perfect. All done with the laser. Now I have to do the pad and rear driveway. It will have to wait until spring. So far it has cost me about 48,000.00 that includes the guys that I had to hire for the flat work, and the crew that did the brick work on the retaining walls. These guys are great. But I did all the rest with my wife of 53 years. This laser is just wonderful to use and very accurate and affordable. The John Deere is wonderful also. I don’t think I’ll ever forget the fact I was able to do all of this at my age and never worked as an engineer or in construction before. So far I have saved 100 thousand dollars on the concrete part. You don’t need a laser any better than this one. Even the flat work guy was impressed with this one. He had a laser that cost him $3200.00. And he chose to to use mine.
