This is probably the most common question, but it is rhetorical. There are a lot of good, high-quality laser levels, it is simply impossible to single out the best one of them!
If it is difficult to make a choice, then proceed as follows:
1. Choose 2-3 models you like
2. Write down all the pros and cons for each model in the table. (price, functionality, build quality, ease of adjustment, scope of delivery, and so on, up to the design)
3. Based on this data, make a choice.
I also recommend looking at the article “How to choose a laser level?“
With any laser level, for comfortable work on the street, you need to use a laser receiver.
With such a receiver, the working area at the laser level increases from 80-200m in diameter, depending on the model. Or from 300 to 1500 meters for rotary laser levels, also depending on the model.
Another advantage, in contrast to the optical level, is the fact that you can work alone without a partner.
It is impossible to say unequivocally. It all depends on the degree of illumination.
If the sun shines directly on the work surface, then at 3 meters it is unlikely that something can be seen.
If the line is in the shadow, then 7 meters maximum.
If it is deep twilight outside, then at 20-25 meters the line can be seen with the naked eye.
If it is night outside, then the line can be seen from 50 meters and above.
For comfortable work on the street, you need to use a special laser receiver, which is sold separately. If we talk about rotary laser levelers (for example, Firecore FRE207R), then such a receiver is usually included in the delivery package.
The pendulum is locked mechanically, it is simply clamped, resulting in a slight displacement.
In this mode, the level is not marked, this mode is designed specifically for marking lines under any arbitrary slope.
To mark the level directly, you need to unlock the pendulum and install the device on a fairly flat surface.
There is no question of “fix” here at all, since this is the absolute norm for such a mechanical fixation of the compensator.
A small backlash is allowed, there is nothing critical about it. In other cases, the locking mechanism is broken, if it is provided. There are laser levels that do not have a pendulum lock. They are few, but they are there.
All laser levels with a pendulum-type compensator on MAGNETIC dampers have this effect, expressed to varying degrees.
This unstable magnetic field affects the pendulum, hence such micro-pumping of the lines.
This effect is completely absent in laser levels with an electronic compensator on servos, for example, as in the FIRECORE FIR-GL8-EA or Huepar DT03CG.
Depends on how many planes are enabled at the same time. Also, the duration depends on the color of the laser. A red laser requires less energy than a green laser.
Another frequent question: – ” Which batteries to buy, expensive or cheap?”. To answer this question, it’s best to watch this video.
Due to the high brightness of the lines, the camera matrix cannot convey the true thickness, so the lines appear thicker in the photo.
Both are great. 4D just might be more convenient in some situations and that’s it.
For a better understanding, watch this video.
The video is old, but there will be understanding. The receiver is needed to work on the street at a longer distance, when the line is not visible. Not all laser levels can work with the receiver. For more information, see the laser level reviews in the technical specifications.
All other things being equal, the green laser is seen better, it is brighter. For a better understanding, watch this video.
With a guarantee, as everywhere else – you will have to prove that the failure was not your fault. That you used it correctly: at an acceptable environment, temperature, that you did not wet it, that you did not drop it, did not hit it, and so on…
So, in principle, everywhere with all the equipment. So it’s complicated.
For example, you can register with Huepar (information in the instructions) and get a 2-year warranty, but how it all works in practice is difficult to say.
If the device is in active use, then after a month it looks as if they played football with it.
The camera is definitely better. This is a kind of digital sight.
On the screen there is a sight, this sight is most convenient to make a measurement to the desired point during the day on the street.
In the sun, the laser point will not be visible at 10-15 meters. Here only a digital (camera) or optical sight saves, the latter is now practically not found.
There may be several options:
1. A hair has come off or not one (very thin wire)
2. The contact inside the module is broken
3. The radiator burned out
4. The battery runs out
You need to disassemble and look at the contacts associated with the speaker.
As a rule, the angle of 90 degrees between the verticals is not a declared characteristic, and if the error is up to 5 mm when checking at 5 meters, then consider yourself lucky.
You can try to adjust it more precisely. This is done with the same bolts that adjust the position of the laser modules individually (for more information, see the laser level reviews).
But here you need to understand that by adjusting the angle of 90 degrees, you will simultaneously affect the accuracy of the vertical. Therefore, you need to look for a “golden mean”.
To solve this issue, the usual nail polish is perfect.
It is almost impossible to find out which laser modules are installed. Just look at the quality of the performance and the laser line.
Theoretically, you can replace it, but this process is definitely not easy. You can try to find the glass here.
You need to search on Aliexpress. They differ from each other, so you need to look at which laser diode is suitable for your laser level. For example, you can send a photo of your module and ask this seller.
These stray lines occur with all green laser levels regardless of brand.
Because of the very high luminous intensity of the green laser, reflections from any small reflective surfaces occur.
Also oblique short lines appear when laser light passes through the glass junction of the protective tower, where a small portion of the laser line is refracted and a visible parasitic short line appears.
This is not a defect, it is a normal phenomenon for laser levels with cone prisms and protective towers. Instruments with red laser also have such beams, but they are just faintly visible.
