If you work in construction or take on building projects frequently, and you are still using that old bubble level, it is time to upgrade to a laser level. However, while many line levels are great for indoor use, many models are not the greatest when it comes to outdoor projects. On the other hand, rotary laser levels are great outside, but you can totally take them indoors for all your projects as well.
The major selling point of rotary laser level is that they have better visibility and dramatically longer range compared to your stands line laser level. It is those aspects and the fact that you can rotate the beam, often through a remote control without having to move it, that are a major boon for outdoor work. However while you could spend endless hours reading reviews and trying to find the best rotary laser level for your needs, we have gathered up our top picks.
Although a rather obscure brand, the Topcon RL-H4C does lack some of the nice added features of other models, but excels in what you need it to do. Compared to other models in terms of accuracy, range, battery life, and even IP rating, it trumps them all. However, the major downside is that unlike other models, it doesn’t come with all the add-ons like a tripod. However, it does have a slope-matching and anti-drift tool that makes it good for use on uneven surfaces.
Without a tripod or any or attachments included, the price is kind of ridiculous. However, what you are paying is for that 100 hours of battery and the 2,600-foot range, both of which utterly lap other competitors. Although it only has one speed of rotation, it does have an IP rating of 66 that means it can take quite a bit of exposure to the elements.
No matter what project you try to tackle, the Dewalt DW079KDT kit can help save you time and stress. This kit not only features a great rotary laser level, but it comes with a number of accessories all packed into a tight storage kit that allow for better ease of use.
With the standard +1/8 in. at 100 feet accuracy, and a higher-than-normal range of 1,500 feet, you get a professional grade laser level that comes with its own tripod. However, one of the nicest features is that it also comes with multi-volt batteries that you can swap out so if one dies, your day isn’t completely over. You also have the option to rotate at either 60, 250, or 600 RPMs so you can adjust the speed.
However, for as many accessories as the kit does come with, there is no grade rod which can be problematic on certain surfaces. Another issue is that, while the display is easy to use, it doesn’t feature an LED screen. This means that if the sun is shining, you have to cup your hands over the display in order to see it.
The Johnson 99-006K rotary laser isn’t for professional construction uses unlike many other of our top rotary laser level picks. It has the standard +1/8 in. accuracy, but that only extends to up to 50 feet. It has self leveling, but you can only move it three degrees instead of the standard five before you need to reset it. Finally, you only have a relatively minor battery life of 20 hours. However, while it comes in a little short, it does have features that not every rotary laser has.
It excels in its ability to adjust the speed at 200, 400, and 600 RPMs, but the best feature is probably its visual and audible alarms that let your know when you are going beyond its leveling rage. This is something that is a must when you only have a maximum range of 800 feet. While it does come with a number of crucial accessories for outdoor use as well, it could be a little sturdier built.
The Bosch GRL300HVCK is another rotary laser kit that is all about the accessories, from the tripod and laser detector all the way to protective eyewear. However, perhaps the best accessory it could come with is a remote control that allows you to adjust the settings and turn the laser on and off from a distance.
While it comes with a lot of nice accessories and it is easy to carry with its two-handled system, it might not be quite as powerful as some may need. It has a pretty standard accuracy of +1/8 in. at 100 feet, but it only has a range of around 1,000 feet. It also falls a little short with a battery life of only 40 hours and no backups to change into. If you do construction for a living, you should aim higher with other options, but this Bosch model is great for more casual use.
THE CST/Berger RL25HCK is built for durability, making it the top rotary laser level for those that demand a certain amount of toughness from their tools while not sacrificing functionality. What sets it apart from its competitors is its durable housing that makes it so you don’t need to worry about it being damaged by your heavier equipment in transit while also keeping everything water and dust-proof. It is this toughness that makes the RL25HCK one of the best professional use rotary lasers.
As for the specifics, it features a good +3/32 in. at 100 feet accuracy while having a range of 2,000 feet, something that is only beat by the aforementioned TopCon models. It also comes with a nice 85-hour battery life and multiple batteries, to give you even longer use in between charges. However, while it comes up short to TopCon in both battery and range, it does allow you to adjust the rotation speed between 150, 300, and 600 RPMs. It also has the added benefit of coming with a tripod, 8-foot leveling rod, and a strong storage case.
