The leveling is not exactly a pendulum but a gimble, basically a compound pendulum. One reviewer checked it with a water level which is far more accurate than anything I had at my disposal so I will tend to believe his assesment. Did OK on vertical lines but the horizontal line depended on the wall being plumb. Not necessarilly true in an older house. Obviously, I am impressed. which is what the book says it will.
Wow, where to begin. I fought through one project with that thing and then I found this one.I took this one into my basement where I had some room and checked it against the specs in the owners pamphlet (never get a real manual anymore) and it exceeded everything published. Accuracy was right on as far as I could check with my yardstick using the mm. The major drawback is that the leveling device doesn't seem to be damped in any way so you have to wait for the thing to settle down after making the adjustment to figure out just where you are. The adjustment rack is very smooth allowing pretty precise adjustment. In normal lighting it will give you a visible beam for about 20 ft. Got this thing in yesterday. Being the type of guy that gets-a-new-hammer-and-everything-looks-like-a-nail, I couldn't wait to try it out.
Hanging it may be a bit dicey because I can envision it starting to swing in a cross breeze unless it is damped by weights or something. The mount is a real jewel. scale. You can also park it about any way you want to; hang it from something, sit it on something, stick it in the wall (two pins), hang it from a nail or put it on a tripod. probably substantially further if I darkend the room a bit.
I haven't tried mine but with so many other options I doubt I ever will. For around 50 bucks, If you want something better, go for it, your money. Some reviewers noted that the tripod mounting feature is recessed to far for a average camera tripod to work without some finagling. Let me preface this with the fact that I had a single beam type that used the pin-in-the-wall deal to accomplish horizontal lines. It allows a vertical adjustment of 4 1/8" with 1 1/4" per turn on the adjustment.
The book does not recommend its use outside and it would be pretty worthless in bright sunlight but around twilight it should work just fine. That and the whole shebang liked to rotate out of true on the pin itself (only had one pin holding it). If you use a target (used a gray steel yardstick) I could get out to at least 25 ft.
would highly recommend it to anyone. This laser level works very well, definently would purchase it again if need be.
I checked the level lines projected against my fluid level, and as expected they lined up perfectly.The carrying case has room for storing a spare battery, a very nice touch.The wall mount is slightly confusing to use at first, but you'll get used to it quickly. The surface mount works exactly as expected, the lines projected are clear and bright, and it adhered nicely to a fluid tripod. Just got this. So far I've used it to hang a series of pictures on a wall at the same height.
This would only work if the wall was perfectly flat and also accurately perpendicular to the laser source. Sorry but that is a physical impossibility. There is no way for a leveling device to project a level laser line on an arbitrary wall from above or below the line. A great little tool for indoor leveling. There are plenty of mounting options - you can pop it on a shelf, use the magnetic base, hang it from a cord or use the little spikes to fix it directly to a wall. It seems to be pretty accurate and definitely bright enough in any room I have used it in. I haven't tried the tripod mount, but it seems like there are solutions to the longer required screw thread.I noticed a number of people lamenting the lack of an elevation function on the laser.
It can be hung on drywall with its unique pin device making it easy to layout the established height. It is being used to install suspended ceiling. I am very pleased with the product and its price. Shipped on time as promised. Took it to work (volunteer church construction) the next day.
