Here are 5 best rotary laser levels you can buy in 2020:

Best Overall: Topcon RL-H5A Self Leveling Horizontal Rotary Laser Level

Topcon Corporation is a Japanese conglomerate (with its US headquarters in California) and one of the largest manufacturers of optical surveying equipment. Which is another reason why one of its bestsellers is taking up #1 position in our list of the best rotary laser levels.

Best Overall
Topcon RL-H5A Self Leveling Horizontal Rotary Laser
Topcon RL-H5A Self Leveling Horizontal Rotary Laser Best Rotary Laser Level For Construction
9.6Outstanding

Best For

Advanced users. General outdoor and indoor construction, surveying, excavation, and grading. Suitable for day-night applications in all types of weathers. Best in class product.

Top Feature

IP66 grade weatherproof built provides proofing from dust, rainfall, and shock.

Pros
  • High accuracy
  • Weatherproof, strong built
  • Laser range of up to 2500+ feet
  • Impressive battery life up to 100 hours
  • Significant long-term warranty up to 5 years

Cons
  • Heavy at 13 pounds (including the hard carry case)

Overview

A deserving successor to the legendary Topcon rotary laser level – the RL-H4C – this self-leveling beast is capable of shooting laser up to 2600 feet (800 meters) with an industry best 0.005-degree accuracy i.e. about 1/16 of an inch at 100 feet.

Its weatherproof, sturdy built will ensure that it plays anywhere you put it regardless of the climate.

Especially intended for outdoor construction applications, the Topcon RL-H5A has an extraordinary 100 hours of battery life, which further makes it one of the best tools in the market.

There is nothing else that you need to depend on when you have this Topcon model plus some additional accessories like a tripod. According to our experts, it is even qualified for measurements at night provided you make apt use of the complementary receivers/reflectors.

Verdict

If you want a companion for general construction and grading applications, this Topcon model will be fully worth its steal price.

Most Durable: Trimble Spectra Precision LL300 Self-leveling Rotary Laser Level

Another export from the East in this list is Spectra Precision, a subsidiary of the Japan-based Nikon-Trimble Company Limited, known for its high-quality surveying and construction tools.

Spectra LL300: Most Durable Rotary Laser Level
Spectra LL300: Most Durable Rotary Laser Level

Best For

Beginners; general construction with low range and rugged requirements.

Top Feature

The optional remote control (sold separately) can be used to control the unit from the rod position when doing slope matching.

Pros
  • Full weather and dusty proofing; shockproof for up to 3 feet
  • Fast setup and easy to use
  • Comes with optional remote control and complementary Spectra Precision HR320 detector with bracket

Cons
  • Bulky

Overview

What sets Spectra Precision apart from other brands is not its 5-year full on-site warranty but its claim of full weather and dust proofing. We actually tested this out in harsh conditions of snow and rainfall, and were surprised to find that the accuracy matched with the claim.

The optional RC601 remote control will come in handy if you deal with slopes while excavation or grading.

The Spectra Precision Laser LL300 also offers single cross-axis manual slope mode with cross-axis self-leveling, providing more accurate grade measurements. Which is a boon to civil engineers who usually struggle and end up spending more time in measuring areas with slopes.

Compared to the Topcon model, this one has just one drawback of having a low range (up to 1650 feet compared to 2500 feet). It’s slightly heavier at 20 pounds, which limits its portability unless you own a vehicle.

Verdict

If you have been toiling with your manual rotary laser level for years and want to shift to modern technology, this is the best rotary laser level you can start with.

Best Value: CST/berger RL25HV Horizontal/Vertical Rotary Laser Level Kit

CST/Berger is a partnership company with a history dating back to the nineteenth century and is now owned by the popular German conglomerate Bosch, which in itself is a testament to this tool’s high quality and precision.

CST/berger RL25HV: Best Value Rotary Laser Level Kit
CST/berger RL25HV: Best Value Rotary Laser Level Kit

Best For

DIYers and house owners with large projects. Best value for money.

Top Feature

Variable speed and angle setups.

Pros
  • Variable speed/angle scan
  • Durable housing design for better outdoor construction use
  • Hibernate mode for saving battery
  • High range of up to 2000 feet
  • Complementary remote control, wall mount, and tripod

Cons
  • Short term warranty of 2 years

Overview

If you are looking for a complete package and a mix of the above Topcon and Spectra Precision models, look no further.

The CST/Berger RL25HV comes with a remote control, RD1 detector with bracket, laser glasses, and aluminum tripod (39 inches), and 8-feet leveling rod.

This rotary laser tool is perfect for large projects, is an all-in-one tool, and gives you total value for money.

This modern self-leveling rotary laser level has features where you can vary the speed (150, 300, 600 RPM) as well as the scan angles (10, 25, 50 degrees), which is a boon to engineers who struggle with a fixed angle.

The 85 hours of runtime is less compared to Topcon, but it does come with an indicator (battery level gauge) to notify you that it’s running low on juice.

The class enclosing top further gives it a better tactile proofing from dust, debris, and heavy rainfall.

We also particularly love the hibernate mode which saves a lot of battery power when you are out taking a break with your colleagues at the site.

Verdict

This CST/Berger self-leveling rotary laser level is a power-packed product that will take care of all your requirements. It does not get any better than this.

Multiple Uses: Johnson Level & Tool 99-027K Self-Leveling Rotary Laser Level System

Johnson is an American company and believes in the marketing itself as “Made in the USA”.

Johnson 99-027K: Versatile Self-Leveling Rotary Laser System
Johnson 99-027K: Versatile Self-Leveling Rotary Laser System

Best For

Advanced users. Large job site excavations, as well as indoor projects like drop ceilings.

Top Feature

Heavy-duty build.

Pros
  • Range of 2000 feet
  • Pendulum locking mechanism
  • Dustproof
  • Visual and audible alarms about range and battery level

Cons
  • Detector does not have a built-in level

Overview

Johnson’s “Made in the USA” products are known for their versatility and tough build (IP66 rating). This self-leveling rotary laser level is no different. With a locking mechanism that protects the pendulum, you can transport it between sites without the tension of breaking the plumb.

The visual and audible alarms provide you notification about the range as well as battery levels, which again makes it a direct competitor of the CST/Berger model reviewed above.

It is dustproof and can withstand light shower on all weathers, making it suitable for external uses as well.

The range is around 2000 feet that can cover large construction sites without the need of any external support. However, this Johnson 99-027K kit still comes with a 13-foot grading rod, clamp detector, tinted glasses, and a magnetic target.

Verdict

The Johnson 99-027K is targeted at users who have a diverse set of projects. Like the CST/Berger and Spectra Precision models above, this is also a great tool for advanced users who work with both small and large projects. It does what it promises and a neat job at that.

Best Budget: Johnson Level & Tool 99-006K Self Leveling Rotary Laser Level Kit

Another Johnson model on this list, it is a combination of economic and powerful.

Johnson 99-006K: Best Budget Rotary Laser Level
Johnson 99-006K: Best Budget Rotary Laser Level

Best For

Beginners handling low-cost projects.

Top Feature

Low price.

Pros
  • Work both horizontally and vertically, making it versatile
  • Self-leveling with pendulum protection guard
  • Comes with complementary tools
  • Inexpensive

Cons
  • Range of up to 800 feet only
  • It does not have a sturdy construction as compared to other tools above

Overview

This is the lowest priced rotary laser level on this list. A dumbed-down version of the 99-027K, this economic model is known for its self-leveling capabilities and a range of up to 800 feet.

External usage is limited but it still boasts of a high accuracy ratio compared to other models in this price range.

We also found that the red beam is clearly visible up to 100 feet in broad daylight, which should take care of most applications for beginners.

The Johnson 99-006K kit comes with complimentary soft carrying case, a 13-foot grading rod, LED one-sided detector, a contractor grade tripod, freestanding target, a drop-ceiling bracket, and laser glasses. All of this in a single package at a steal price makes it the #1 choice for beginner engineers and homeowners.

Verdict

If you are on a budget and still require the functionalities of a rotary laser level, this is the model to go for. Its features give other top models a run for their money.

Go through this help guide below to get a grasp of the factors that you need to count in while choosing the right rotary laser level.

If you have already selected your pick, use this guide to ensure that it will live up to your project expectations. If you are a beginner user, don’t forget to check out the tips and FAQs at the latter part of this article.

Which Is The Best Rotary Laser Level To Buy?

Every user is different. And every user has their own set of requirements. A house owner may need an inexpensive rotary laser level for indoor works and small outdoor projects like fence construction.

On the other hand, an advanced user – a civil engineer – will need a robust rotary laser level for excavation, grading, landscaping and similar heavy-duty construction/surveying projects.

And not all rotary laser levels are capable of everything. As noted in the reviews above, some models provide a long range (the Topcon RL-H5A provides the longest range at 2600 feet) whereas some provide resistance from weather conditions like dust and water.

Therefore, it is important to identify the type of needs you want to be accomplished with your rotary laser level.

Top 4 Rotary Laser Level Parameters

The best way to choose the right product is to go through these top laser level parameters and then select your pick.

Range

If you deal with sites that are long and wide in terms of area, then a rotary laser level that can cover a few hundred meters will fall short. You will struggle with your laser level and might need to borrow a long-range one. To avoid such issues, it is always a good idea to base your selection on your required range.

If you are a DIYer and only work with small projects, a rotary laser level with small range will be enough. The Johnson 99-006K offers a range of up to 800 feet, which will be sufficient for your basic needs.

If your requirements are large, then consider the Topcon RL-H5A model we have reviewed above.

Accuracy

Almost all the models reviewed here offer very good accuracy with low error quotients. Typically, errors enter your calculations when long ranges are involved. For shorter projects, all the six rotary laser levels we reviewed above will provide highly accurate results and plumbs.

According to our experts, the Topcon RL-H5A is the best rotary laser level for accuracy.

Durability

In an ideal scenario, you want to take your rotary laser level in any type of environment. Especially if you work outdoors, having a tool that can withstand debris, continuous dust, and occasional rainfall is necessary. Otherwise, a big investment like this will go down the drain.

Although most of these brands offer years-long warranty, damage from external elements is usually not covered. Therefore, it is wise to select a level that is fully waterproof and weatherproof.

Both the Topcon RL-H5A and Spectra Precision LL300 are the best tools for external, all-weather use.

Battery Life

Most of these precision instruments work on alkaline batteries. The concept of Lithium-ion has not yet been introduced here, even though we have used customized tools that work on 5V charging.

More than the total running time that you get from a single charge, you must look at supporting features such as hibernation mode and automatic shutdown. These will ensure that your rotary laser level does not waste precious power and the whole unit last longer.

Now that you know the four main factors to judge your potential buy, here are expert recommendations for the two most common types of users.

Best Rotary Laser Level For Professionals

Here are our top picks of best rotary laser level for builders and professional contractors:

Professional contractors will need a device that can deliver a lot of features for both interior and exterior applications. You will need to look for high performance, long working range, durability, warranty, battery life and many other superior features.

For people who are willing to make an extra investment to get the best laser leveling tools, here are top choices for you.

Best Overall

9.6Outstanding

The Topcon RL-H5A has an impressive range (with detector) of 2500+ feet (800 meters). You can use it for larger projects (both indoor and outdoor) than other common laser levels on the market.

The second option is the Spectra Precision L300 which has the optional remote control for large site surveying and excavations. From a durability point of view, it even fares better than Topcon.

The CST/Berger RL25HCK laser level does not fail to impress either in terms of range it can offer or the durability. With an extended range of 2000 feet (600 meters), it is among the best rotary laser level kits you need today for a large project.

Best Rotary Laser Level For Home Use

Top choices of the best rotary laser level for homeowners:

As an avid DIYer, sometimes you will need to use the rotary laser levels to handle a number of home improvement projects like hanging cabinets or building a backyard deck. In this case, we recommend you to invest in an affordable rotary laser level for home use.

If you are looking for an inexpensive rotary laser level, then either of the Johnson models above is great. They have good ranges at a very good price and are built like a stone that will take some hard hitting to break.

These models are also great as budget-friendly options.

Tips To Choose The Ideal Rotary Laser Level

These are some additional tips to help you buy better:

  • Go for complete packages than laser level-only ones to save money on accessories like glasses and tripods
  • Always check out the company website before making the final purchase. Critical information about warranty and product registration will help you maintain your product in the long run
  • Invest on a tripod if you choose to get a standalone rotary laser level. It will make outdoor projections easier
  • Check out additional features like hibernate mode and battery indicator if you are torn between two models
  • Trust a brand that you have previous experience with (e.g. Bosch and Spectra Precision are widely known international brands)

Frequently Asked Questions About Rotary Laser Levels

Some of the most frequently asked questions and their answers about rotary laser levels:

Is red laser beam better or green?

It depends on the application. Both beams are effective, and can be improved through the use of laser glasses.

Should I get a tripod when using a rotary laser level?

Yes, it is recommended. A tripod will make your task of plumbing and surveying easier.

Are all rotary laser levels waterproof?

No. Only a few models provide full proofing from water (rainfall and snow). The Topcon and Spectra Precision models are the only ones that provide complete weatherproofing.

What is motorized self-leveling?

It is a type of self-leveling where the plumb is set by a motor than a pendulum. Most of the models today use a rotating pendulum for this purpose.

Safety Tips While Using A Rotary Laser Level

These are some critical tips to follow while using your rotary laser level to avoid accidents:

  • Always switch off or pause the laser level when not in use, especially during outdoor usage
  • If your laser level does not have pendulum lock-in, take extra care during transportation. If the pendulum breaks, the self-leveling functionality will be lost
  • Always carry an extra set of batteries
  • If your laser level is not being used for a long period, remove the batteries and keep them separately to avoid leakage
  • Always keep the laser level in the hard/soft casing it came with

Conclusion

According to our experts, the best rotary laser level in the market today is the one by Topcon. The versatility and scope of applications that the RL-H5A boasts of make it a true companion of civil engineers and household DIYers alike.

The models by Spectra Precision, and Johnson are equally good with their own set of pros and cons. When you make your choice, base your decision on their individual characteristics and cross-check them with our buying guide.
