A rotary laser level can be a really useful tool to have, then you are working on uneven surfaces, acting as a 360-degree marker for leveling out holes or making sure that individual objects are all set up at the same height. While they aren’t the simplest piece of equipment on the market, they are definitely great for their intended purpose and have hundreds of applications across a huge range of different tasks and situations.
If you feel like you will need one for an upcoming project or want a replacement for a less effective leveling system you are already using, then they can be a great option. The biggest problem will be how complex they can be, though: you can’t just choose a random design and size and assume it will work perfectly.
Here are ten different rotary laser level models, along with their specific details and the jobs or working conditions they are best suited for.

The Pendulum system is able to automatically balance out your current level measurements, and there is a lock mode to keep it set to a certain angle. On top of that, the laser beams can be customized with three different rotation speeds and six length settings.
The body of the kit, as well as its tripod, are made with durable materials, and the glass that protects the laser is able to withstand a lot of punishment before breaking, keeping the key components safe.
This leveling laser offers a lot of features that can help with very niche measuring projects, letting it fill roles and assist with tasks that a larger or more general rotary laser level would struggle to deal with properly.Check Price on Amazon ➞
6. Johnson Level & Tool 99-005K Rotary Laser System
The 99-005K set contains a small rotary laser level tool and various extra pieces of gear. The laser itself can be split at 90-degree angles for vertical and horizontal measurements, making it easier to use for walls and other raised surfaces, and you can adjust the rotation speed to get different laser intensities and measurement results. The ability to reverse the scan line can also help you get more accurate measurements during important jobs, especially if the tool is placed near a wall or other object.
The system offers two different scan modes (Large and Small) to get different beam intensities and measurement types and is contained in a durable body that won't break or malfunction easily.
This rotary laser system is simple and doesn’t have any overly-complex features, but still provides everything you might need for a range of job types, making it ideal for small-scale use.Check Price on Amazon ➞
7. CST/berger RL25HVCK Rotary Laser Kit

Rotary Laser Level Buyer’s Guide
Buying a new rotary laser level isn’t quite the same as purchasing a lower-tech measuring tool, like a spirit level: there is a lot more to consider, and a lot of features that may or may not actually be useful to you in practice. This is especially true if you are buying one for the first time since it is very easy to assume that more features are always better. Just like any other complex tool, you will want to focus on your needs and requirements over your wants, especially if you are wanting the best results possible.
There is no point measuring something if it is going to be extremely inaccurate, so finding a decent level of accuracy should always be your first priority. Everything else is usually secondary – you can work around physical issues or range problems, but not severe accuracy issues that ruin your measurements completely. However, the “perfect” amount of accuracy will vary based on each project.
There is not really a laser system that’s 100% accurate all of the time, so it’d make sense to go for the highest accuracy, but that is not always the best idea. In many cases, you can get away with slightly lower accuracy, especially if you are measuring objects that are going to be very close to the laser. Accuracy gets worse with distance, so smaller areas rely on it less. On the other hand, if an area is really wide open and your rotary laser level has a long-range, accuracy will become very important as you get further away from it.
Keep in mind that not all accuracy scores and levels are checked in the same way, too. One laser level might say that it has a certain accuracy at a range of 30 meters, while others might count theirs at 15 meters instead. If you are not careful, this can throw you off, especially if you are only comparing the accuracy deviations themselves and not the ranges they are associated with.
Another vital part of any laser level system is the laser itself. If you can’t see the beam or can’t adjust it to the right position, then it is not going to help you properly, and might even lead to more inaccuracy than usual. To avoid this, a lot of rotary laser level units offer adjustable settings, including rotation speed and vertical/horizontal angles.
Being able to switch between vertical and horizontal measurements makes it far easier to level out walls, tall objects and other items that need to be positioned in a certain way where height doesn’t matter. This could be furniture, temporary walls, decorations, reinforcements, or even just markers for future stages of a project. If this doesn’t work, you can sometimes attach a smaller laser system to a wall and use it that way, but this isn’t always an option.
Speed also matters. Adjusting the speed can change how visible a beam will become, but it can also result in increased power usage. The larger and brighter the beams are, the more energy they will use, this can cut down battery life significantly. The brighter the surrounding environment is, the brighter you will need to make the lasers to compensate, so having to work with a single pre-set beam intensity can be a problem sometimes.
Very few lasers are designed to work exclusively indoors or outdoors, and most of them are able to deal with both environments fairly well. However, this doesn’t mean that they are perfect for those situations. For example, when you are using a laser outdoors, you will ideally want weatherproofing, waterproofing, reinforced glass and extra stability. On the other hand, if you are primarily using it indoors, dust proofing, a durable exterior, and a magnetic base can be more important.
Raw durability is also really important, as with most construction tools. You never know when something can get bashed or bumped, especially if you are on a larger construction site, and even the smallest fall can cause damage to an unprotected laser level. The glass might shatter, or the lasers themselves might get knocked out of alignment – if you are really unlucky, the electrical components inside might even permanently break.
Self-leveling is an excellent feature that can speed up measurements significantly and has the added benefit of reducing inaccurate measurements caused by human errors or accidental nudges. While they can still have limits, it is often worth getting rotary laser levels with this feature over those that don’t have it. Some will have it as a toggleable option, whereas others will have it as the default setting: it depends on the model and manufacturer.
Technically, they are not actually more accurate, and can sometimes even be worse in terms of accuracy than a purely manual laser level. However, the fact that they can automatically compensate for bumps, uneven surfaces, and different weather conditions (and, in some cases, even the temperature of the current area) makes them much more likely to get correct measurements within their own margins of accuracy.
Laser line detectors are a must-have if you are trying to keep track of measurements. Without them, a beam might seem almost invisible in most conditions – in some cases, you might even have to kick up dust or smoke just to see where the laser is shining.
Did you know?
Many rotary laser levels rely on rechargeable batteries, which often have a charger that is compatible with standard outlets. Make sure you always have a spare battery ready if you want to reduce downtime.
