Rating of the TOP 20 best laser levels of 2020-2021

Description of the device

The Ak435 360 degree device easily rotates around its axis. The bright red body is mounted on a hard plastic base on 3 legs, one of which is fixed, and the position of the other 2 can be adjusted.

At the bottom of the device is equipped with a coupling with a 5/8-inch thread for a tripod, allowing it to be placed vertically at the desired height, and on the back there is a vertical plate with holes designed to mount it on the wall.

On the front side there is a laser emitter window, and on the opposite side there is a compartment for 2 AA batteries. The mode switch is installed on the side. At the top of the body there is a round bubble level eye.

The self-leveling level is equipped with a simple but reliable compensator on magnetic dampers, which starts within 5 seconds after turning on the device and produces a sharp loud sound if the device goes beyond the permissible tilt.

The limit is 3° in any direction. This feature of the level design is a great advantage, since the presence of an alarm allows the master to avoid mistakes when marking the surface.

The only disadvantage of the design is that when you turn on the device, both planes are projected at once, i.e. you cannot switch only to horizontal or only to vertical. But the device turns on very simply, by simply turning the toggle switch.

How to choose a laser level for your home?

To choose a reliable device that will last a long time, take into account the following points::

1. Error . No more than 0.5 mm, and preferably within 0.2-0.3 mm.
2. Radius of action . 15-20 meters is enough for a room; if necessary, you can use a receiver.
3. Management . It should be simple and understandable. It is very convenient to use devices controlled via a smartphone.
4. Tool protection . The level should have rubber inserts that will protect the device from falls.
5. Equipment . Determines how convenient it will be to use the device. The case is needed for storage and transportation. Various mounts and brackets allow you to save both money and time, since you do not have to deal with the separate selection of accessories. Glasses improve the visibility of the rays.

Control MX2

The Condtrol laser level is quite interesting. It has Russian roots, but is produced in China. When using this device, only two lines can be drawn. The device operates for about 30 hours on two batteries. Fastening can be done in various ways:

• on a tripod;
• using a magnet;
• using self-tapping screws;
• on a strap or clip.

Despite the rather small alignment angle, it is enough to carry out simple repairs in an apartment. The device is semi-professional. This is because it can be used with a special receiver, which allows you to increase the projection range.

Condtrol x360 laser level lines can be built both together and separately. This makes work much easier and saves battery power. The case is reinforced, which protects the device from mechanical damage. It can be mounted on various tripods. The standard “Control” laser level kit includes a carrying bag and an adapter for attaching a battery.

Customer Reviews

I bought the DEKOLL 12-HR level for the construction of a bathhouse and renovation of the bathroom. I haven’t tested it at long distances, but I can say that the device 100% fulfills its purpose. With his help, he completed all the work with maximum precision. It is worth noting that the beam is clearly visible even in strong lighting.

I spent a long time choosing a level in the middle price segment and bought Condtrol NEO X2-360. The accuracy is high. It is a pleasure to work with due to its ergonomics and light weight. Works at a distance of up to 5 m, while the beam does not spread. I think it’s worth its price of 8 thousand.

Additional options and features

In addition to the main parameters, there are also some additional ones. They make things easier, so it's more about usability. After all, additional functions affect the final result only indirectly or partially.

Self-leveling

In order for the measurements to be correct, the level must be installed vertically upward. In simple models, their position is checked with simpler devices, usually a bubble level. In some models it is built into the body, in others it is not. Then you have to resort to ordinary construction, which is not entirely convenient. In addition, incorrect readings are possible - if during operation it changes position and you do not see it, the work will be performed incorrectly. To avoid such a situation, you have to double-check the position of the device several times.

Self-leveling (self-compensation of a small angle of inclination)

Some laser levels have a self-leveling or self-leveling feature. When deviating from the vertical by a small angle (usually up to 4°), they adjust the position of the mirrors and prisms so that all readings are correct. If the tilt exceeds the maximum permissible, they either make a sound/give a light signal, or turn off the beams. Operation is restored when returning to normal.

Having a laser level with this function makes it easy to set up the device at the very beginning of work. Also, during its use, you don’t have to worry that it has changed position - it will give a signal.

However, sometimes the level needs to be set at a certain angle. The presence of a self-leveling function will not allow this to be done. Therefore, it is advisable to purchase a model in which this function can be blocked.

Self-shutdown

This function allows you to save battery power. If the device does not move for 10-15 minutes, it turns off. On the one hand, this is useful, on the other hand, some jobs require more than 15 minutes and shutting down can be annoying. Whether you need this feature or not is up to you.

Automatic shutdown is not always good

Operating temperature

If you plan to work in the warm season or only indoors, the temperature does not matter. Basically, a laser level can be operated at temperatures from +5°C to +40°C, that is, they are only suitable for heated rooms or work in the warm season.

Most laser levels are designed to work in a heated room

If you need to choose a laser level for working outdoors with the possibility of operation in the cold season, there are “frost-resistant” models that can withstand temperatures down to -10°C. Even more frost-resistant ones must be looked for specifically; there are very few of them.

Mounting type

In addition to the standard installation of the laser level on a horizontal plane, there may be several additional options for mounting it:

On a special tripod. Most often needed for outdoor work, but some work (drawing horizontal lines on walls when hanging furniture, for example) is also easier to do with a tripod. A tripod is sometimes included, sometimes purchased separately

When purchasing, pay attention to the diameter of the thread on the body of the level - the tripod must have the same one. On magnets. Magnets are soldered into the body of some models

This makes it possible to attach it to any metal surface/part. The type of fastening affects the ease of use. On a special magnetic stand. Some models of laser levels come with a small plastic pad into which magnets are soldered. A platform is installed on a metal surface, and a level is placed on it. Self-tapping screw/nail. A special hole is made in the body of the level into which the head of a nail or self-tapping screw is threaded. Not the most convenient way of fastening, but still.

Everything is clear with these options. You can, of course, do without them, come up with your own way. These are simply opportunities for more comfortable operation.

Operating principle

The operation of the device is based on the formation of projections of laser beams. The latter are focused using an optical system, which allows you to project lines and points on the desired object. Similar landmarks are used for marking when performing various works.

At its core, any laser level is an optical electromechanical device that visually displays planes, lines and individual points on different surfaces. They are located strictly vertically or horizontally, as well as at a specific angle.

The functions of radiation sources in levels are performed by powerful LEDs. These semiconductors create a monochromatic flux with increased density and a specific wavelength.

Which company should you choose?

Below is a list of the most popular and reliable brands that produce laser levels for both beginners and professionals:

• ADA instruments . A fairly young company that began its production in 2008. This brand specializes in measuring, diagnostic, and other instruments used in construction, geodesy, repair and installation work.
• Bosch . A German company that needs no further introduction. If you are looking for a quality model and have a suitable budget, choose Bosch. Such a tool will serve faithfully for many years.
• RGK . It has been producing tools since 2006 and is considered one of the leaders among manufacturers of construction tools. The line includes budget models for household needs and for professionals.

Let's return to the question of choice. Why and who needs it?

The average person, before opting for a laser device that can perform independent leveling, should think about whether he can realize the full potential of this level in simple home conditions.

Yes, this device will help when gluing wallpaper, will provide a service when laying tiles, and will be convenient when installing an interior partition. But on the other hand, any of these “home” type jobs can be easily handled by other, cheaper measuring instruments, such as a plumb line and a simple bubble building level.

And the tiny error with which modern self-leveling models operate is unlikely to be noticeable to a layman. The above example shows that if it is necessary for a private user to carry out marking, cheaper devices with a similar purpose will be sufficient. Considering the difference in cost, the savings are obvious.

It’s a completely different matter for professionals. For such people, a self-leveling laser product can save a lot of time, effort, and nerves. Nowadays, when there is a constant shortage of either one, or the other, or the third, this property is very important.
