The 9 Best Rotary Laser Level of 2022

Are you a professional looking for a laser level that can spin 360 degrees for your next indoor and outdoor project? Then, a rotary laser level is what you need! Rotary laser level produces high levels of precision measurements 1/8th of an inch at 100ft or 1/16th of an inch at 100 ft. 

Today, the rotary laser level is one of the most preferred choices among home builders and professional contractors. They make single dots instead of lines and spin at more than a thousand rotations per minute. 

Getting the best might be challenging. So, we’ve written this guide to present you with the best rotary laser level for your next project!

Rotary Laser Level Buying Guide 

Rotary laser levels are excellent for indoor projects. They shoot a 360 degrees beam either horizontally or vertically. A rotary laser level can also be used outdoors with a laser detector or a grde rod. The laser detector and grade rod make the rotary laser level great for excavation projects. Below is a complete guide on the rotary laser level:

1. Rotary Laser Level Rotation 

When using a rotary level, you can establish a horizontal or vertical plane because the beams shoot in a 360 degrees direction. The beam of light is a single dot that rotates between 100rpm to 1000rpm per minute. This gives the appearance of a 360 chalk line when the rotary laser level is done. The light beam is created from the diode. In the case of a rotary laser level, the diode is a semiconductor that gives light when current goes through it. 

2. Leveling Method of the Rotary Laser Level 

There are three unique ways the rotary laser levels. 

Manual Leveling 

The operator levels the laser by adjusting the laser to bubble vials with manual leveling. The bubble vials are built into the laser. The problem with manual leveling is that the accuracy will be dependent on the quality of the level and the eye of the operator. Nevertheless, this is the least expensive laser level available. 

Self Leveling 

The self-leveling laser level means that the laser levels itself. It balances itself through the use of a pendulum and magnets. The accuracy of a self-leveling rotary laser is about an inch per 100 feet which is far better than a manual. 

Electronic Self Leveling 

Electronic self-leveling is also known as automatic self-leveling. Automatic self-leveling works by using a series of servo-motors. It used the servo motors to lift itself to a high level of accuracy. The accuracy level when the rotary laser level is used in this method is about 1/16th inch per 100 feet. 

3. Rotary Laser Level Color Wavelength 

The wavelength determines the color of the rotary level laser. The wavelength is determined by the diode, which is measured in nanometers. The green rotary level laser is brighter than the red laser. The green beam laser system is called the GreenBrite technology, and is about four hundred times brighter than the red laser. However, whether you choose red or green, you won’t be able to see the color of a rotary laser level outdoors. If you use the rotary laser level outside, you will need to use a laser detector. 

4. The Intensity of the Rotary Laser Level 

The level of laser light power determines the intensity of the laser level. The laser light power is measured in milliwatts. Usually, class one and class two are classified as low power, and they are in the range of 0.4mw to 1mw. The average laser level should be a classIIIA. The ClassIIIA has power between 1mw to 5mw. At the levels of 1mw and 5mw, your eyes are safe if it hits a laser. If you are purchasing a laser closer to 5mw, it will be bright and expensive. Lasers from 5mw to 500mw require control. ClassIV lasers have a power higher than 500mw and are very hazardous. 

5. Working Range Of the Rotary Laser Level 

The distance a rotary laser can go is often within a specified diameter, measured in feet. The rotary laser level is usually the center of the range. It can also be the distance in any direction, the radius, and half of the specified diameter. The range of the rotary level laser can be up to 2000 ft in diameter. This is achieved when a detector is outdoor. However, when used indoors, you can see the laser, and the distance can be more significant. 

Guide on How to Calibrate a Rotary Laser Level 

Step 1 

Start by placing your manual rotary laser level on a flat surface. You can also use a tripod and put it in a room with two opposing walls. 

Step 2 

Put your rotary laser level about one inch from one of the walls and at least twenty inches from the other. 

Step 3 

Orient the laser along the axis of the vial. This should be the vial that you wish to level. The vial must be pointing to both walls. 

Step 4

Check your unit, and you’ll see two screws. The screws correspond to each vial. You should turn the screws until the beam is level along both the axes. You will know its level when the two vials show bubbles resting between two black lines. 

Step 5

The next step is to turn on the lasers. Then, mark where the lasers hit the closer and far wall. 

Step 6

Then, move the laser about one inch from the far wall. 

Step 7

Then, level the laser and proceed to adjust the height. Adjust the height till it hits the mark on the wall. 

Step 8

Go to the near wall and check the difference between the first mark and the laser line. If the difference is less than or equal to your level of accuracy, then the rotary laser is appropriately calibrated. However, if the difference is significant, your unit needs further calibration, which will lead you to step 9.

Step 9

Go back to your unit and adjust the laser. Adjust the laser till it hits halfway between the two marks you made. The mark made between the two marks is called the true level. 

Step 10

Remove the screw cap made for the vial. Then, adjust the vial to its level. 

Step 11

After you have leveled your unit using the vial, you can then conclude that your unit is appropriately calibrated. 

How to Utilize a Rotary Laser Level 

Step 1 

Now that you have calibrated your rotary laser level, the next step is to set it up for use. Set it up on an elevated flat surface. It is best to use a tripod for best results.

Step 2 

Place the level on your chosen surface and then turn it on. 

Step 3 

If you are using a self-leveling device, you should give it some time to find a level. The process of finding a level will take your unit about a minute. However, if your unit is the type that uses manual leveling, refer to the user guide for more information. 

Step 5

Keep a keen ear for the beep, which usually indicates a connection with the laser. The laser cannot be seen in broad daylight. 

Step 6

Proceed to aim the rotary laser level at the wall or any other surface you want to find a level. Then, make the marks that will guide your installation. 

Using a Receiver With the Rotary Laser Level 

If you are working outdoors, you may need to use a receiver. This is because the beam cannot be seen outdoors. However, if you are working indoors, you may not need to use a receiver. But two factors will determine if you’ll need a receiver or not. These are the size of the room and the brightness. 

If the distance is up to 20 meters, you should be able to see the laser lines. However, you will need a laser detector if the space is more than 20 meters. For the most part, rotary laser levels are used outdoors, so they’d usually come with laser receivers in their boxes. 

How Does a Rotary Laser Level Work With a Receiver? 

The workings of a rotary laser level along with a receiver are simple. The rotary level releases a beam that the receiver can detect. It is important to note that not all receivers are the same. So, before using a receiver, you should check if it’s compatible with your unit. The receivers are usually mounted on a stick and have indicators indicating the center of the laser line. So, there are visual indicators and sounds that a single operator will achieve. 

Rotary Laser With Vertical or Horizontal Leveling 

Most of the reputable rotary laser levels use horizontal leveling. When the laser starts up, it would by itself find a true level. It will also stop if it is disturbed or knocked during the process. This means that you won’t be getting any inaccurate readings. The expensive rotary laser levels use the vertical function for tasks such as frame leveling. It can also be used for plumb work and steel work. 

The Difference Between Red and Green Rotary Laser Levels 

The last few years have seen more people use the green beam lasers. Regarding accuracy, there isn’t much difference between the red and green beams. However, the green beam is preferred because of its high visibility. The human eye can see the green beam better and it is usually brighter. The downside to the green beam is that they cost more because the components of a green diode are traditionally more expensive. 

If the laser you choose is for internal projects, then you should select a green beam. However, if the leveling jobs are going to be done outside, you should save costs and go for the red beam. This is because neither red nor green will be visible to your eyes outside. 

Rotary Laser Levels and the Grading Function 

A high-end rotary laser level will most likely enable grading. Both single and dual will be available on high-end rotary levels. This makes them excellent for water drainage. Single grades allow for slopes on one side of the axis, and the dual allows for two slopes. If you are required to do compound grades, invest in a dual-grade rotary laser level. 

Rotary Laser Levels With Scan Modes

The scan mode is one of the best features found on a premium rotary laser level. This allows for the beam to rotate in the selected working area. When you narrow the angle of the laser, the beam will become more visible because it is more concentrated. It is also great for busy work sites. This would limit laser exposure to the area you are working on. 

What to Consider When Choosing the Best Rotary Laser Level 

1. Leveling 

Before you choose a rotary laser level, you should first determine if you want a self-leveling or manual leveling rotary laser level. However, you should select a self-leveling rotary laser. Self-leveling units use the pendulum and magnets to determine the level. When the laser level is placed on a flat surface, the pendulum helps find the leveling level. 

2. Mounting 

When choosing a rotary laser level, it is best to choose the one that lets you work hands-free. Many of the best rotary laser levels use different amounts to achieve a hands-free position. If your budget can’t afford one with a tripod, you can poke holes into the drywall to stabilize your unit. 

3. Accuracy 

An excellent rotary laser level should have a high accuracy level. Accuracy is essential for you to carry out your work in an effective manner. A good model should have ½ deviation at thirty feet. The right deviation will give you outstanding results. A suitable self-leveling laser will provide the best laser line.
