The Methodology: What I Considered When Picking the Rotary Laser Levels Featured Above
So, how did I pick the rotary laser levels mentioned above? To help you out, here are some criteria that I depended on:
There are two ranges to consider: one is the indoor range and the other is when you include a detector. Typically with a detector, you’ll get about 1,500 to 2,500 feet of range depending on the unit. Indoor ranges, on the other hand, vary from 65 to 200 feet.
A higher price tag comes with a rotary laser level that has a significantly larger range. This means that it’s suitable for outdoor use and not just for indoor DIY projects. Therefore, you’ll have to think ahead: will you use the rotary laser level for home remodeling or a construction site outside?
Aside from that, when it comes to farther ranges, you might also want to think about the accuracy. Sometimes, it pays to invest in a model with both a higher accuracy (discussed below) and a bigger range so that you’ll keep your measurements as precise as possible.
A rotary laser level’s accuracy is typically expressed in inches per 100 feet. For example, DEWALT 20V DW074LR MAX Laser Level has an accuracy of 1/8 inch per 100 feet. On the other hand, the LL500 Exterior Self-Leveling Laser Level is a unit that has an accuracy of ± 1/16-inch at 100 feet.
As mentioned above, accuracy goes hand in hand with the range of your rotary laser level. Also, when choosing between brands, take a look at the base measurement. Some models use 30 feet for measurement while others typically use 100 feet, which is usually more accurate.
Similar to the operating range or distance, higher accuracy results in a pricier unit, so think about where you will use your tool. If you are simply looking for an entry-level unit, it’s best to go for 1/8-inch at 100 feet, otherwise, you might want to go with specifications higher than that, such as 1/10 to 1/16-inch.
Usually, rotary laser levels are either red or green. The most common laser level is red and it is okay for indoor use. However, if you intend to have a brighter sightline for outdoor use, I advise going for green lasers. That’s because they tend to have better brightness compared to red lasers.
When you compare green and red lasers side by side, you’ll see the difference. Green is typically easier to see for the human eye compared to a red color. That’s also why green is often used for night reflectors, along with yellow and orange.
However, with that said, green lasers aren’t ideal for snow due to their specific technology, so I advise not to use them for a winter project. Aside from that, green lasers are also slightly more expensive when compared to red-colored units. Not only that, but green lasers also consume more power.
Therefore, if you’re looking for a laser that will last for a long period when it comes to battery life, a red laser will do the trick. However, if you need extra precision and don’t mind the higher price tag, green lasers are worth investing in.
4. Rotation speeds and angle
The rotation speed is variable in most indoor-specific laser levels. If you are considering getting a rotary laser level for home DIY projects and remodeling, I advise getting a variable speed level since it improves the visibility of the laser indoors when you set it to a slower speed.
Indoor laser level usage doesn’t require a receiver, which is where the variable speed will come in handy in improving the visibility of the projection line.
Aside from the speed, the rotation angle is also present in most higher-end laser levels. For instance, allowing your laser to be turned from 15 to 90 degrees means that it’s usable for stairway projects.
A jobsite-ready rotary laser level should have some manner of protection. For instance, an IP54 or IP66 rating is often seen in such tools. This ensures that no matter the weather conditions and unforeseen accidents, your laser level is safe.
Durability is highly important for jobsite use, so it pays to consider a rotary laser level with a high level of protection. Aside from being IP rated, do consider a unit with rubber bumpers for shock absorption, as well as protective over-mold construction.
Fortunately, most of the units that I mentioned above do have great levels of protection, such as 3 to 5 feet of drop protection. This will help a lot in case you have a lot of work on the jobsite with poor visibility and someone accidentally bumped your rotary laser level off the course.
With that said, you still need to take your rotary laser level for a yearly recalibration to avoid losing accuracy. This is especially true for those who use the laser level frequently, such as with jobsite use.
Included Features and Accessories
A rotary laser level usually comes with various accessories to get started, such as adapters, detectors, holders, hard cases, and the like. Some units even include a tripod so you don’t have to buy it separately.
If you want to get a rotary laser level that has a slope mode, you should find one that has a remote control. Some units cannot be tweaked in terms of the slope so they’re not advisable for stairways, but if you have a remote, it is possible.
Do consider a unit that has a long battery life so you don’t have to frequently charge it. It also pays to have rechargeable batteries and other options of powering it up, such as AC, so you’re not limited to alkaline batteries when on the jobsite.
Battery life and power options also add price to the rotary laser level. However, if having additional power options is important for you, it’s best to invest in a tool that has a rechargeable battery or even AC power.
Moreover, some tools, such as the DEWALT DW074LR use the 20V MAX battery that’s shared across most DeWalt tools, so you simply have to swap batteries when needed. This makes it convenient when it comes to battery replacements.
The laser level should have straightforward controls, such as navigating through the settings. In most cases, a laser level has an LED light that blinks when the unit is self-leveling to let you know when it’s working.
A plus point would be a battery gauge because it helps you determine your usage. A rotary laser level that has this kind of feature is the KAIWEETS 3 X 360 Self-Leveling Construction Laser, which is helpful if you’re having a busy schedule and are away from a power source.
A basic rotary laser will only project horizontally, but most of the picks I mentioned above have vertical projection as well. Therefore, pay attention if you need a plumb mode for your rotary laser level or if you need a simple horizontal guide.
With that said, some units do have a diagonal lining mechanism. This would be useful for certain projects that require diagonal aligning, such as a staircase. If most of your work involves diagonal angles, go for a laser level with this kind of feature, which is usually triggered using a remote for manual adjustments.
A gracious warranty period of about one to three years is sufficient for any tool – and a rotary laser level is no exception. This is especially the case if you intend to use it for jobsite projects. After all, accidents will happen from time to time, so it brings peace of mind if you know that your tool is backed up by a warranty policy.
Overall, my top pick is the DEWALT 20V DW074LR MAX Laser Level, which is a jobsite-ready tool with a high self-leveling range and already comes with a tripod adapter. My runner-up pick is the Topcon RL-H5A Self Leveling Horizontal Rotary Laser, which has a high self-leveling accuracy of 1/10 inch at 100 feet.
For those who are on a budget, the SKIL 65ft. 360° Red Self-Leveling Cross Line Laser Level is a great choice due to its diagonal option for crafting stairs and other diagonal projects. However, if you’re looking for a professional tool, the Bosch GRL300HVG Self-Leveling is a green laser level with high visibility and variable speed adjustment.
A laser level that’s ideal for large jobsites is the LL500 Exterior Self-Leveling Laser Level due to its long-range of 1,650 feet and the Johnson Level & Tool 40-6535 Electronic Self-Leveling at up to 2,000 feet.
If you are looking for laser levels with manual modes, you will like the DEWALT DW074KD Laser Level Kit, Rotary with Laser Detector, Johnson Level & Tool 40-6606 Self-Leveling 360 Degree Line Laser Level, Spectra Precision LL100N Laser Level (requires a separately-purchased remote), and the Johnson Level & Tool 40-6507 Manual-Leveling Rotary Laser Level Kit.
A laser level variable speed options include the Johnson Level & Tool 40-6543 Self-Leveling Rotary Laser Level. Meanwhile, the Huepar Three-Plane Leveling, Alignment, and Horizontal Line’s laser has a green projection that is ideal for outdoor use.
Last but not the least; the KAIWEETS 3 X 360 Self-Leveling Construction Laser is a great choice for traveling due to its rechargeable battery and gauge to let you know when it’s time to charge.
