Habitual for many repairmen and builders, the water level in some situations does not provide the required convenience and accuracy of work. A significant limitation of such an instrument is that it is capable of measuring only the horizon. For minor repairs at home, such opportunities are usually sufficient, but when it comes to larger-scale work, you have to choose more functional tools. And one of these tools is the laser level.
The advantages of the laser level over the water are undeniable - it is multifunctional and is ideal for large-scale work.
This unit has a lot of advantages. And its value is also rather big. Therefore, it is imperative to understand how to choose a laser level in order to spend money wisely and profitably.
Difference between electronic and pendulum laser levels
Understanding how to choose a laser level, it is necessary, first of all, to understand the difference between the pendulum and electronic varieties of this tool. Pendulum laser level for the home is equipped with a special pendulum with light-emitting diodes. Allows you to accurately set the vertical with horizontal.
The principle of operation of a self-leveling pendulum rotational laser level.
It will be useful when performing both repair work in the house, and operations on a building site. This laser level allows you to simultaneously perform up to 5 measurements in different planes, which completely eliminates inaccuracies.
The electronic laser level has a more complex structure and is most often used by professional builders. In the purchase of such a tool for home there is almost no sense. The design of the electronic laser level includes a number of slope sensors operating using complex calculations. Errors are absent even when measuring at long distances.
Also available on sale levels of mixed type with different alignment mechanisms. They can be used both at home and in professional conditions.Back to table of contents
Laser level selection by beam designation
When choosing a laser level, you need to be able to understand the different designations of the beam. It happens:

From each other, these types differ in the LEDs used, their power and location features. Point used on the surface. They are able to give only a point. Line laser level can project lines vertically and horizontally. Used to build all sorts of planes.
The most complex design have rotational laser levels. The LEDs in their design rotate at a fairly high speed. Due to the built-in glass prism, the light beam is divided into vertical and horizontal. The beam allows to measure, scan and reproduce any slope on the surface. As a result, on the measured surfaces, segments with variable thickness can be seen. This is ensured by the difference of the sweep of the beam, due to which the highest accuracy is achieved.Back to table of contents
Difference between household and professional laser levels
Laser levels can be divided into household and professional. Household models are used in the alignment of corners, repair and installation of windows, repair of ceilings, sticking wallpaper, fixing a variety of household trifles such as kitchen drawers, bookshelves, etc.
Household levels allow you to measure the surface no further than 10 m. The error is usually 0.5 mm / m. Both household and professional models are equipped with high-quality diodes. The only difference is that in the household beam has a smaller thickness.
Marking ceilings, curbs and baseboards using a laser level for interior work.
Any laser level can project vertical and horizontal lines. It will take about 5 seconds to measure and align with the household level. Some models are equipped with a special button holding the emitted rays at their intersection at a right angle. That is, the user can tilt the tool in any direction, and the projection of the light will still remain at a right angle. This feature is useful when performing a variety of repair and construction works. For household needs, pendulum or manual leveling are usually applied. On the projection - linear and point.
A professional-level tool for the home is usually not bought, because it costs too much for the average person, and it does not pay off if it is used exclusively for small household work. The error of such tools is reduced to 0.3 mm / m, in some models the distance of the beam is increased to 100 m, on average - to 30-50 m.
Most often, the levels are sold complete with the necessary and useful accessories, which include:
- additional batteries;
Additionally, you can separately buy clamps, detectors, targets, etc.Back to table of contents
Level selection by type of design and principle of operation
On the modern market of building tools there is a very large assortment of laser level models. There are both complex in their design units, and fairly simple devices. Decide exactly which one to give preference to yourself, taking into account the peculiarities of the upcoming tasks and financial opportunities.
The simplest option is the usual rack level with a special laser device. The work is inconvenient and very limited. For large-scale repair and construction will not work. It has a minimal cost compared to more functional counterparts, and is used primarily for small household tasks.
The professional level can build a projection of any plane, any lines, crosses and points.
More "advanced" laser levels are equipped with a special mechanism that provides self-leveling. Rack level in this case is not needed. The tool is able to independently take positions in relation to the vertical and horizontal. Made in the shape of a cross. The beam is projected on 2 sides from the center and in one direction vertically. Most often the tool is placed on the wall. Features of the design and principle of operation somewhat limit the use of such a laser level when working with the floor.
Professional laser levels belong to a separate category. Such a tool has almost unlimited possibilities in the field of construction of planes and measurements. Excellently applied both in everyday life and in professional construction. For home use, you can choose a relatively inexpensive model. A professional tool can be very expensive. Usually for successful use of this level you need a tripod. Professional laser levels are able to project horizontal and vertical beams, crosses, dots, oblique and straight lines at different angles.
The most functional of all existing options are rotational levels.
Such a tool at the same time can project several parallel-directed beams at almost any height.
This feature allows you to carry out installation work without pre-marking, immediately on the projection of the emitted rays. Are more expensive than all the previously considered options.
Thus, the range of laser levels is quite wide and varied. Guided by the above information, you will be able to choose a tool without any problems in accordance with your needs, peculiarities of the upcoming work and the available budget. Have a good choice!
