Best Self Leveling Lasers

Cross line lasers Self-levelling project horizontal and vertical lines onto walls, ceilings and floors. And it is only through the self-levelling function that the laser lines are projected perfectly straight onto the wall.

If this function were not available, you would have to adjust the laser laboriously by hand. In addition, you can rarely align it as well as a self-levelling function could.

However, such a function also has its limits. You can find out what they are in this text.

What does a self-levelling function do?

In simple terms, the self-levelling function automatically aligns the laser lines. With a cross-line laser, it does not matter whether the line is horizontal or vertical, both are always aligned exactly straight by this function.

However, the self-levelling function can only do this to a certain extent. For example, most devices can compensate for a slant of +- 5 degrees. In case of a higher inclination, a warning is given, which is realised either by a warning tone or a flashing laser line.

This function achieves a measuring accuracy of +/- 3mm per metre. However, this value always varies a little from unit to unit. Such a measuring accuracy cannot be achieved with manual measuring aids.

How does self-levelling work?

Self-levelling cross-line lasers bring the laser unit into alignment with the help of a pendulum system. To ensure that the levelling process does not take too long, the free-swinging pendulum is damped by a magnet.

The laser diodes responsible for projecting the laser lines are attached to this pendulum. Thus, the old technique of the pendulum is still used today in our laser measuring units.

However, if the levelling range of +-5 degrees is exceeded, the pendulum rests against the wall of the housing and can therefore always roll back and forth a little.

This makes it impossible to measure accurately because the laser lines shift a little with every vibration. The only remedy is a locking function or, as with some Bosch cross-line lasers, a clever design that holds the pendulum against the inner wall of the housing.

The locking function | The most important feature of a self-levelling cross-line laser

Without a locking function, it is very complicated or even impossible to measure slopes precisely. Simple devices with a self-levelling function are only designed to project laser crosses straight onto the opposite wall. Only with the locking function is it possible to measure slopes precisely. By the way, the same applies to models without a self-levelling function; these are virtually always “fixed”.

The locking function fixes the pendulum. This prevents the laser lines from arbitrarily moving back and forth in response to vibrations when measuring slopes. Because if the pendulum cannot swing out, it will never be able to lie still and will always slide back and forth a little. Another advantage arises during transport. By fixing the pendulum in place, damage caused by permanent movement of the pendulum is avoided.

Our expert tip: Avoid models that give warnings when the locking function is switched on to remind you that the locking function is activated. The manufacturer probably meant this function well and wanted to prevent accidental measuring errors. However, it is very irritating to have a permanently flashing line when measuring slopes.

The disadvantages of a self-levelling cross-line laser

Without the locking function, measuring slopes becomes more difficult.
Without the locking function, measuring slopes becomes more difficult.
  • Only +- 5 degrees can be compensated by most devices. Therefore, precise positioning is still necessary.
  • If the locking function is missing, it is often not possible to measure slopes precisely.
  • Some devices still give warnings even though the locking function is activated.
  • Often 20£ more expensive to purchase than “rigid” cross line lasers.

Is it absolutely necessary to have a self-levelling cross-line laser?

Whether a cross-line laser with or without self-levelling is better depends on the intended use. If you are a do-it-yourselfer and regularly carry out surveying work with high precision and a long range, you should opt for a device with this practical additional function, which saves you a lot of work and also saves time.

This is the case, for example, if you are moving into a new house where there is still a lot of renovation work to be done before you are ready to move in.

In the case of simple alignment work, for example when hanging pictures, you can do without a self-levelling function. Hobby jobs and small jobs done quickly also do not necessarily require precise alignment assistance through self-levelling.

In these cases, careful alignment of the tripod is sufficient to achieve good results. Cross-line lasers with this self-levelling function are about 20 pounds more expensive to purchase than models without self-levelling.
