Best Self Leveling Laser Levels

Indispensable for construction and renovation work, the laser level is a tool that is no longer reserved for professionals. Everyone can now get it and benefit from its ease of use and precision.

But how do you find the right laser level among the many models available on the market? For this, you must take into account the important characteristics and choose the one best suited to your type of work.

What is a laser level?

A laser level is a tool commonly used in construction and work of all kinds but not only, but many DIY enthusiasts also equip themselves to perform simple jobs while having the assurance of working just right.

The most common laser is a rotating device, which, once placed on its tripod will automatically level itself and then begin a permanent 360 ° rotation to project a horizontal reference line. This line will then allow plumb work.

Before the invention of the laser level, two people were necessary to obtain levels: one behind the dumpy level and another at the front equipped with the staff. Today, a single worker is able to get precise levels and very quickly.

The laser levels generally work with batteries and offer a long enough autonomy to carry out hours of plots. So no need to work in the sector since it must be able to be done on-site totally without electricity.

How to choose the best laser level?

Measuring Accuracy

This is the first criterion to favour when buying a laser level because it is especially for this parameter if we choose this tool. Expressed in nanometers per meter (nm / m) and determined by the wavelength, the precision is relative to the thickness of the laser beam per linear meter of the beam.

It is generally between 0.20 and 0.50 nm / m. Simply put, the lower the measurement, the greater the visibility distance of the beam and the more precise the laser. But be aware that your choice will depend on the type of work you want to do. To give you a reference, a model with an accuracy of around 4.5nm / 15m is particularly suitable for laying tiles and other squaring work.

Working Range

It is also an important parameter for a standing laser level. It is thanks to the light beam if the vertical, horizontal or angled marks are more easily materialized. Its projection distance generally varies from 5 and 50 meters but can go up to 100 m.

Here again, you must choose according to the type of work to be carried out. For indoor use, a range of 15 m may do the trick depending on the size of the room. On the other hand, it is imperative that the line is visible up to 25 m at least if you are looking for an outdoor laser level for your large-scale construction sites.

Type

The Point laser level is the simplest model on the market right now. Ideal for small interior works like the installation of partition rails, the point level makes it possible to precisely mark angles at 90 ° by making points appear. It offers a good projection distance ranging from 5 to 20 m, with an accuracy of 0.5 to 0.8 nm / m.

Point laser level

The line-level works the same as the point model. That is, with the same projection distance and the same precision except that it projects a single visible line. It is especially suitable for horizontal and vertical alignment indoors on spans of around 10 meters, especially for the installation of mouldings or plinths.

line laser level

Cross-line laser level allows you to make squares by projecting two lines reproducing a 90 ° angle. Offering the same projection distance, and the same precision as the previous models, the cross laser level is intended for indoor use, particularly in laying tiles or fixing furniture.

cross-line laser level

Rotating laser level is the most complex model, and yet the most efficient. Dedicated for professional use, the rotary laser level is essential for very large indoor spaces, but especially for outdoor work, such as levelling or earthmoving. It projects a line using a diode, up to 360 ° and offers a range of up to 50 m with an accuracy of 0.25 nm / m.

Red or green laser level?

In the building industry, the red ray represents 90% of sales. The green laser takes its place slowly but the diodes remain more and the laser technology more pointed due to the stronger heating of the laser diodes.

The green laser is a more visible laser

The visibility of a green beam is higher than that of red beams and its localization quality is much higher than that of any instrument with a red beam laser diode, which increases the laser range.

Concretely, the more visible the laser beam, the greater the working comfort, the greater the range and therefore the greater the productivity gain. An additional cost to be favoured for use in bright conditions or on working amplitudes of 20 to 40 m of distances indoors beyond the use of a reception cell becomes essential because the laser beam is no longer visible.

Why the green laser is more visible?

The human eye only distinguishes light having a wavelength (measured in “nm”) visible in the spectrum. The human eye sees light falling between approximately 385 nm and 725 nm, the maximum at 555 nm. The green colour located in the middle of this range and reaching 550 nm is, therefore, the most visible light for the human eye.
If you look at the specifications of most indoor red beam laser levels, you will see that the wavelength of the red beam is on average 635-670 nm.

The green laser level has a laser beam with a wavelength of 532 nm. The green colour occupies the segment of the spectrum which is 4.3 times more visible!

Laser receivers

laser receiver

Some call it a receiver, others of a detector, others of a detection cell. It’s the same thing: an electronic device that receives signals from the rotating laser (or pulsed laser). Do not confuse with the target (rule where a laser cell can be fixed).

To work with a laser receiver, you must always set the rotating laser level to maximum speed so that the detector can easily receive the maximum number of signals. For a standard rotary laser level, set it to 600 rpm. Some large site laser levels intended for machine guidance, have rotation speeds greater than 1000 rpm. This speed is used for so-called digger guide receivers which are supposed to work over even greater distances.

Battery

If you choose a laser level for outdoor projects, you will have no choice but to buy one with good battery life. Rotating laser levels offer 30 hours of use per charge in this regard and are therefore very effective. In addition, you will no longer have to worry about finding a charging point on your site for your laser level.

Accessories

When we talk about accessories for the laser level, we think first of all of the tripod, which allows working at height. In this case, we recommend that you turn to a model coming with this support, so as not to have to buy it separately. Another element that we find very useful is wall mounting. It makes it easier for you to take height measurements.

The integration of other accessories such as protective glasses, flexible target or the 360 ​​° swivel plate can make the difference, depending on the use you plan.

how to use laser level

How to use a laser level?

Although the laser level is a fairly simple tool to use, it is important to know how to position it in relation to your needs. For the installation of a shelf, for example, start by drawing a mark on the ground with a pencil to indicate the position of one of the brackets.

Place the level opposite and perpendicular to the wall, making sure that the beam passes through the mark that you have previously drawn. With a measuring tape, measure the desired height and put it on the wall where the beam passes, then draw a cross to indicate the crossing. Once this first point has been drawn, you can then place a second level point for the second square.

To do this, simply place the laser level in front of the first point using a pole or a stepladder as support. The horizontal beam should go through the mark you have already made. You will then only have to transfer the desired distance between the two brackets, along the beam with the meter and draw across.

Which brand to choose?

Among the brands of references, we can quote you Bosch, DeWalt, Stanley, Einhell, Makita. All these brands make excellent products and we cannot recommend one more than another. It is above all about affinity with the brand! Even if Bosch often pulls out of the game with its German quality and innovations that are always well thought out, especially in terms of ergonomics and transport.

How much do laser levels cost?

There are at all prices! We can find cheap laser levels around 40 pounds at entry-level which will largely suit DIY enthusiasts who want to simplify their lives up to a few hundred pounds for construction equipment dedicated to building professionals for example. Namely that the investment quickly pays for itself when it is used on-site since, for certain operations, the laser level allows you to work alone where two people would have been necessary. In addition, it offers a level of precision much higher than that of human tracing.
