Why should someone consider chucking their tried and true water bubble leveling tool in favor of a rotary laser level? It’s a good question. If the answer is simply that the laser level is new, well, that’s not good enough.  

A rotary laser level is an essential tool for construction professionals and DIYers looking to achieve precise horizontal and vertical alignments. This handy device projects a laser beam that rotates 360 degrees to create an accurate reference point or laser plane.

It has to have some real, quantifiable advantages before getting rid of something that’s worked for centuries makes any sense. Fortunately for proponents of best laser levels there are a number of solid reasons to make them part of your toolkit including:

• Simplicity and significant time savings.
• Eliminating the need for marking guidelines everywhere.
• Easily adaptable to indoor or outdoor applications, large and small.
• Eliminating the need to reset should something or someone knock the level out of whack.

With the right rotary laser, you can work faster, smarter and achieve perfectly straight and level alignments every time.  Below we’re going delve into what a rotary laser level is, review what we consider to be the 10 best laser levels of 2023 available on the market today and then go into some of the things you’ll want to consider before buying one of these technical marvels.

The rotary laser level was invented in the 1960s by a company called Spectra Physics. 

What is a Rotary Laser Level?

The Rotary Laser Level uses a beam of light to create the equivalent of a chalk line that can be referenced to ensure things are properly oriented. The width of the beam is dependent on the size of the diode emitting it with narrower being better because it allows for greater precision.

Early laser levels were limited in their power and so were limited in their usefulness; typically confined to indoor projects where the light they produced was easier to see.

Today’s more powerful lasers mean that newer laser levels are equally effective both indoors and outdoors, where they are used on most of the world’s large scale construction projects including dams, skyscrapers and superhighways.

The rotary laser level rotates 360 degrees up to 1000 times per minute with some being effective out to 2000+ feet. In essence, they create a plane of light that is extremely accurate and negates the need for multiple readings and elaborately drawn reference lines.
