How to Choose the Best Rotary Laser Level – Buyer’s Guide

Choosing the best rotary laser level could be a pretty difficult task due to the technical aspects that you have to consider as well as some basic features that you need to look for. However, as a matter of fact, selecting the best rotary laser level on the market shouldn’t pose any challenge to you at all.

In order to get to this stage where you can select the best without breaking into a sweat, you would need to understand some basic principles and other information that are essential to achieving this milestone.

This could be pretty difficult to wrap your head around but this article aims to clear up that difficulty, and make purchasing the best rotary laser levels a process that you would breeze through.

When selecting the best rotary laser levels, here are some features to look out for:

1. Type of Rotary Laser Level

Basically, there are two types of rotary laser levels and this is based off on their mode of operation. There are the automatic lasers which are also referred to as self-leveling lasers due to the fact that you require little or no effort to operate it and perform all the functions that you need for you.

Upon powering it up, you would eventually get your actual and accurate level line and provided it is on a surface where it isn’t disturbed, you can be assured of a perfect or completely accurate value. Second is the manual rotary laser type which is also great because you could get an accurate value as well.

However, it is highly essential that it is properly set up, otherwise, you might end up with a highly inaccurate value. Manual rotary lasers can be used in place of its automatic counterpart. The deal breaker is that if it is even marginally disturbed, establishing your accurate level line afterward would be extremely difficult.

This is why it is advised that they should be used for smaller projects.

2. Laser Range

The range of a  rotary laser is one of the main features that you need to look out for when you intend to select the best on the market. The type of rotary laser that you need depends on the specific nature or purpose it would be used for. This is because not all rotary lasers are suitable for different terrains and for taking different levels in different locations.

The range determines where you can and where you cannot make use of your rotary level. For instance, most cross-line lasers could have a range of between 25 feet and 100 feet. Meanwhile, single-line lasers typically come with a range of 10 to 25 feet.

The laser range that you make use of depends on the area of land that you are working on. Rotary lasers used by professionals or professional-grade rotary lasers more often than not come with a range of over 100 feet.

3. Accuracy

The accuracy of a rotary laser is a great determinant of how to correct, precise or defined that your level values would be. There are certain installations or constructions that require that you get the exact value in order to get a perfect job done. For instance, laying down tiles or installing custom cabinets require very definite measurements to be followed.

This clearly indicated that the accuracy of your laser level is essential. Usually, in order to determine just how accurate a laser level that you are about to purchase is, you need to take a look at two measures which are the distance of the laser source to the surface and the accuracy level which is measured in fractions of an inch.

A smaller fraction and a greater distance imply a more accurate laser level. For instance, a device that has a rating of 1/8-inch at 35 feet is a lot more accurate than a ¼-inch at 30 feet-rated device.

4. Purpose of Purchase

The purpose of your purchase or the reason for which you need a rotary laser is supposed to guide you as to which type to select. This involves thinking of other projects that you might need to use it for in the future. When on track to making your purchase, there are certain questions that you should ask yourself which precludes how exactly you want to use the rotary laser level.

For instance, would the rotary laser be used for getting the perfect level for hanging a painting or a work of art? In this case, you would only need to create a single line on a section of your wall. Or would you be installing suspended ceilings and tiles whereby you would be needing a cross-line?

Or in case you are establishing a construction and building company whereby you would be needing rotary lasers in normal construction line. All these are factors that should determine the type of rotary laser that you end up with. Also, you would need to think about whether you would need it for other purposes in the future and exactly what these purposes could be.

5. Laser Color and Brightness

Although this factor might sound pretty unimportant, it remains one of the most important factors to consider when it comes to selecting a laser level. Outdoor construction usually requires the use of very bright lights in order to see level lines very clearly. This implies that the laser beams would have to possess very high levels of strength and high visibility so that they can be easily seen during construction.

Rotary laser levels usually come with either a red beam or a green beam. Green beams are usually a lot brighter than red beams and may be up to four times as bright as the red beam.

However, since rotary lasers are suited to different uses and green beams are brighter than red beams. This implies that it is more advisable to make use of rotary laser levels with green beams for outdoor construction while laser levels with beams are great for indoor work.

Frequently Asked Questions

Q: Can Laser Levels Cause Damage to the Eyes?

Yes, laser levels can damage the eyes. This is why you need to ensure that you do not overexpose yourself to the laser lights. Basically, any exposure that lasts more than a quarter of a second can cause eye injuries.

Q: What is the Difference Between a Red Laser and a Green Laser?

The major difference between red lasers and green lasers is the brightness. Green lasers are a lot brighter than red lasers making them more suited to outdoor work.

Q: How Often Should I Calibrate My Laser Level?

Laser levels that are used regularly should be recalibrated at least once in every six months. If you do not use your laser level regularly, you could recalibrate every 12 months or every 24 months.

Criteria Used for Review

This section typically consists of the factors that we used in selecting our top 5 rotary laser levels.

1. Price Range

Typically, the various prices of the rotary lasers were one of the factors that we took very seriously since buyers have different budgets. We thought to include laser levels that would fit into a range of budgets ranging from very large budgets to the pretty conservative ones. Meanwhile, we looked out to ensure that the value you get for your money would be maximized.

During this selection process, we compared the price of laser levels to the value that they had to offer. Similarly, we kept in mind that an extremely high price or a moderate one does not imply high-quality products or inferior products as well. This is why we decided to go with rotary lasers from different classes that actually work.

Basically, rotary laser prices are determined by the number of features or how advanced certain features are over similar products. For instance, features such as a green laser or additional mounting features make the price of laser levels increase drastically. These were all factored into the price.

2. Specifications

Rotary laser levels are construction equipment that requires the presence of certain features in order to be used to carry out certain tasks. This implies that there are certain laser levels which are not suitable for certain tasks. In a case such as this, you would have to get another laser level that has the right features for the job at hand.

For instance, in outdoor leveling, there is a need for a laser level with a substantial range and very high accuracy and this could be used for indoor leveling as well. However, if you purchase a laser level that is only suited to be used indoors, you might experience problems will make use of it for outdoor tasks.

In actual fact, you might be completely unable to make use of such laser levels due to the fact that it would be lacking the necessary features or specifications. This is one of the factors we included in our criteria for review. We tried to ensure that the laser levels we selected could be used for multiple purposes.

3. Reviews and Ratings

This is one of the factors that we took extremely serious during the selection process. We were really interested in knowing what people had to say about the rotary laser levels. If they liked it, why did they like it and if they didn’t, why not? All these were considered and we compared the review to review since if you have about 20 people talking about the same thing, there is a very high probability that there is an element of truth to it.

Since reviews are oftentimes the opinions of people who have actually used the product is, it is essential that they are treated important. However, we also kept the fact that some reviews can be purchased at the back of our mind which is why we cross-reference what buyers were saying about these laser levels with our own findings as well. By doing this, we could be certain that we were getting accurate information.

4. Durability

Often times, laser levels are used in construction cases whereby there is a probability that equipment might drop. This is why it is essential that laser levels be of the highest quality, are made from suitable materials and are highly durable. This remains one of the main factors that guided the eventual selection of our top 5 rotary laser levels on the market. Similarly, the manner in which the laser level was considered since this is one of the main determinants of how strong the laser level would be.

Drop test ratings which provide an idea of how strong a laser level is was taken into consideration as well. While considering the durability, we also took note of the warranty period of the laser levels since a product with long warranty periods is a clear indication of great quality. Manufacturers who know that their products are not of very high quality rarely ever put significant warranty periods since there is a certain guarantee that the product might get faulty very early in the usage time.

5. Ease of Use

Irrespective of how any features a machine might possess, if it isn’t easy to use or operate, buyers would have a very hard time getting value for their money. While selecting rotary laser levels based on the factors mentioned above, we also ensured that the rotary lasers, despite the many amazing features that they might possibly be very easy to use.

This was done by looking out for features such as off-level indicators, self-leveling mechanisms, power level indicators, pendulum locking as well as manual overrides. These features make laser levels very easy to operate and guarantee great user experience.


Rotary Laser levels are a very sensitive piece of equipment, therefore a lot of work goes into selecting the best in order to get the best value out of it. Knowing just how much of a headache this might cause, this is why we decided to help get rid of the stress you might have to go through and make your purchase one to breeze through.
