The organization invests billions of euros in research and development and holds thousands of patents. In total, there are about five hundred subsidiaries in one hundred and fifty countries of the world. It is a transnational corporation with a solid market share, offering quality products that meet modern standards. The article presents the best BOSCH levels and laser levels of 2024. Unlike conventional optical and bubble levels, the electronic system is a completely different solution in construction equipment.
Content
Laser units are classified as measuring technology. They are distinguished by high accuracy and ease of control. Thanks to the reliability of the electronics, they give accurate results in all weather conditions. The use of new technologies allows us to consider them not only as measuring instruments, but also as full-fledged intelligent devices that simplify the work of craftsmen. Depending on the principle of operation and field of application, the levels are divided into several categories:
New technologies used in electronic leveling devices make it possible to simplify the process of setting horizontal and vertical planes, including angles.
The schematic arrangement of such models is not innovative. Other manufacturers also have analogs. The principle of operation is to project two laser planes perpendicular to each other. Along the zenith and nadir points, the level is set in space.

The kit is subdivided into basic and advanced versions. The basic one includes:
The extended version also includes all of the above, except for the case, which is made of plastic. It also includes a clothespin and ceiling bracket.
The functionality of the leveling device of this model is expanded by the complete set, since it allows you to measure the perimeter without moving the device itself. In addition, there are special four magnets for which the device can be fixed on metal or magnetized surfaces. Also, the equipment allows fixing the device to the ceiling to mark the upper part of the room perimeter. The ceiling mounts are equipped with an additional lifting device. Of course, such a bracket will have to be purchased separately and for a not decent price, but for professional installers the investment will pay off very soon. There is also a similar wall bracket with a lifter.
The body of the level is manufactured using a large number of bolts. They are needed, first of all, for adjusting the device after shaking or using in adverse weather conditions. The case is perfectly aligned at the factory. The battery compartment is sealed and the cover is made of durable plastic. On some models, there are two tripod mounting holes with different thread bolts on the bottom of the instrument: a quarter inch and a five-eighth inch.
The vertical aperture is correct and slightly tilted, which makes the instrument convenient to use in confined spaces. Therefore, even when densely installed next to a wall, the device projects a laser line onto the ceiling.
An automatic leveling system is integrated into the device. This technology in itself is not new, it can be found on many analogues of competitive brands. Positioning to operating mode takes no more than 4 seconds. Professional models have sound and indicator alarms about the loss of the horizon, household versions are equipped only with visual means of warning. When deviating from the vertical line by 4 degrees, the system begins to signal that the permissible tilt angle is exceeded.
On the side of the body there is a toggle switch for turning on the device and adjusting the slope mark. In the upper part there is a monochrome display and membrane keys for controlling laser beams. This is a very convenient option that allows you to turn on and off the LEDs individually, which saves battery power and does not blind other people.
Levels with a rotating tower project a plane around a circle. This allows several workers to work with receivers at once. The beam is visible at a distance of 200 to 500 meters, and some devices are capable of shooting a beam at a distance of up to 1 kilometer.Such devices are used mainly at large construction sites.

The kit includes:
Rotary levels are used at construction and assembly sites. They form a plane along their radius of 360 degrees due to the rotation of a laser LED tower equipped with a special servo drive. The receiver is placed on a special bar, which is set in turn at those points that need to be targeted. The maximum distance from the device depends on the model type.
Rotary levels cover all the space around them. This measurement technique allows you to use several receivers simultaneously, which greatly speeds up the work process. All devices of this type are equipped with the scanning function. However, it is possible to set the beam at a specific angle through the settings. That is, the device displays the laser beam only at the location indicated by the operator. This option is convenient for aligning window or door openings along one wall, or along the perimeter of a building.
Levels of this model are equipped with a vertical plumb line projection system. The function is also needed for self-leveling on the surface. Morally outdated and cheap devices do not have such functionality, so it is imperative to pay attention to such a characteristic in the technical passport. The option is needed so that you do not have to level the device itself manually using a liquid level in the future. Modern devices automatically line up in horizontal and vertical planes. The compensator works only if the maximum tilt angle is not exceeded.Otherwise, the indicator light comes on to indicate that the instrument is not in a vertical position.
Self-leveling automation is equipped with either a damper or an electronic system. The most widely used are magnetic alignment accelerators. It stabilizes laser beams faster than other systems. It is used on professional devices and is needed for such cases when during operation the level accidentally loses its initial alignment.
With the help of rotary levels, you can make alignment not only in the horizontal plane, but also in any other. To do this, first disable it in the automatic adjustment settings. Once locked, the device can be positioned at any angle. This option is convenient, for example, when decorating walls with decorative materials.
The devices are supplied with sufficiently capacious rechargeable batteries, which last almost the whole day. This is convenient because you do not have to constantly charge them, which can significantly reduce productivity.
The equipment has accuracy only at close range, but with increasing distance, the aiming error increases due to the scattering of laser light. The visibility of the laser beam is strongly influenced by illumination. In bright and sunny weather at a great distance, the laser beam is practically invisible, which again affects the accuracy.
Levels are made compact and lightweight, which makes them mobile. One person can move them from one place to another. It is much more convenient to use such devices than bubble ones. The tripod does not impair his mobility. It does not play an important role, so you can buy even the simplest and cheapest one.
The advantages of this brand:
Disadvantages of the models:
Laser levels are much more convenient to use than bubble levels. They significantly increase labor productivity. Devices equipped with an automatic leveling system allow you not to waste time on setting the level itself. New technologies are more expensive than traditional tools, but they are designed to make the work of craftsmen easier and more efficient.
