All over the world there is no such person who would not know the products of the BOSCH brand. The company is known not only as a manufacturer of electrical devices and equipment, but also as a supplier of industrial, commercial, domestic and building technologies.
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. This is a transnational corporation with a solid share of the sales market, offering high-quality products that meet modern standards. The article presents the best BOSCH levels and laser levels of 2022. Unlike conventional optical and bubble levels, the electronic system is a completely different solution in construction equipment.
Content
Laser units are classified as measuring equipment. They are distinguished by high accuracy and ease of control. Due 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 masters. Depending on the principle of operation and scope, 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 corners.
The schematic arrangement of such models is not innovative. Analogues exist from other manufacturers too. The principle of operation is to project two laser planes perpendicular to each other. At the zenith and nadir points, the level is set in space.

The kit is divided into basic and advanced versions. The base includes:
The extended version also includes all of the above, except for the case, which is made of plastic. Also included is a clothespin and ceiling bracket.
The functionality of the level of this model is expanded by the complete set, as 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 attached to metal or magnetized surfaces. Also, the equipment allows fixing the device to the ceiling for marking the upper part of the room perimeter. Ceiling mounts are equipped with an additional lifting device. Of course, you will have to buy such a bracket separately and at a not decent price, but for professional installers, investments pay off very soon. There is also a similar wall bracket with lifting device.
The body of the level is made using a large number of bolts.They are needed, first of all, to adjust the device after shaking or use in adverse weather conditions. The body is perfectly aligned from the factory. The battery compartment is sealed, and the cover is made of durable plastic. In the lower part of the device of some models there are two holes for mounting on tripods with different screw threads: a quarter and five-eighths of an inch.
The aperture of the vertical plane is correct and slightly inclined, which makes the instrument easy to use in confined spaces. Therefore, even with a dense installation next to the wall, the device projects a laser line onto the ceiling.
The device has an integrated automatic horizon leveling system. This technology in itself is no longer new, it can be found on many analogues of competitive brands. Positioning to the 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 notification. If the deviation from the vertical line is 4 degrees, the system starts signaling that the permissible tilt angle has been exceeded.
On the side of the case there is a toggle switch for turning on the device and adjusting the inclined 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 along 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 firing 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 the laser LED tower, equipped with a special servo. The receiver is placed on a special bar, which is placed in turn at those points that need to be shot. The maximum distance from the instrument depends on the model type.
Rotational levels cover the entire space around them. This measurement technique allows you to use several receivers at the same time, which greatly speeds up the work process. The scanning function is equipped with all devices of this type.However, it is possible to set the beam at a certain angle through the settings. That is, the device displays the laser beam only in the place indicated by the operator. This option is convenient for aligning window or door openings along one wall, or around the perimeter of a building.
The levels of this model are equipped with a vertical plumb projection system. The function is also needed for self-leveling on the surface. Obsolete and cheap devices do not have such functionality, so be sure to pay attention to this characteristic in the technical data sheet. The option is needed so that you do not have to further align the device itself manually using a liquid level. Modern devices automatically line up in horizontal and vertical planes. The compensator only works if the maximum tilt angle is not exceeded. Otherwise, the indicator light will come on, indicating that the device is not in a vertical position.
Automatic self-leveling is equipped with either a damper or electronic system. The most common 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 the level inadvertently loses its initial alignment during operation.
With the help of rotary levels, you can align not only in the horizontal plane, but also in any other. To do this, I first turn off automatic adjustment in the settings. After locking, the device can be installed 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 are enough for almost the whole day. This is convenient because you do not have to constantly charge them, which can significantly reduce productivity.
The equipment is accurate 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 affected by the illumination very strongly. In bright and sunny weather at a great distance, the laser beam is practically invisible, which again affects accuracy.
Levels are made compact and light, 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 reduce its mobility. It does not play an important role, so you can buy even the simplest and cheapest.
Advantages of this brand:
Disadvantages of the models:
Laser levels are much more convenient to use than bubble levels. They significantly increase productivity. Devices equipped with an automatic leveling system allow you not to waste time setting the level itself. New technologies are more expensive than traditional tools, but they are designed to simplify the work of craftsmen and make their work more efficient.
