Buyers’ Guide

Now that we have given you a brief intro on some of the top rotary laser levels, it’s time to learn how to differentiate the features that you might need and those that you might not require. So, let us dive into some of the buyers considerations that might help you in your decision.


For us, the ruggedness of a laser level might be one of the most vital factors to keep in mind. It is important to consider a laser level that comes sealed in order to be protected against dust. Laser levels that come with a moisture and shock resistant exterior are also better off. Even though, you will have to pay a little bit more money for these features, the cash will definitely be worthwhile.

Beam Quality

Why is the beam quality so important you ask? Because without a decent beam, the product won’t do you much good. Now you could easily be fooled into thinking that all of the laser beams are the same, but you need to carefully analyze which beam will suit you best. For example, if you plan on working both indoors and outdoors, then you will need to look into a really high-end unit. You will find them to come with a heftier price tag though. However, if you are planning on using a laser level for casual purposes, then you can also look into an indoor unit only. That way you can also save a bit of cash.


No matter what you buy, price is always an important factor. It can be a real struggle to find the perfect product especially when a tool comes in a wide range of prices. But because a laser level is a precision-oriented tool, it is better if you do not forget the features to save money.


We would definitely suggest you to go for a laser level that has a self-leveling feature. That is because this feature will make your life a lot easier. How is that you ask? Well, you will not need to spend lots of time trying to calibrate the tool once you get it set up.


Agree with us or not, but you will have to consider the potential range of a laser level. What you need the product for is going to define the optimal length for you. But the greater the range, the better.

Battery Life

The battery life will be important to some, but not to all. Nonetheless, we would recommend you to look for the longest possible battery life if you tend to work in more remote areas. Not only that, your batteries should also be capable of being rechargeable. As buying a new battery can cost you a fortune.

Frequently Asked Questions

How does a Rotary Laser Level work?

Rotary laser levels project a beam of light at 360 degrees. This allows the user to establish a vertical or horizontal plane. The laser beam that is produced is actually a single dot of light that can rotate between 100 RPM and 1,100 RPM.
