A Mini-Guide to Choosing Rotary Laser Level
A rotary laser level 
should be carefully chosen just as you pick any other type of tool. There are certain factors you have to prioritize to get the right laser level for your needs. For rotating laser levels, speed, battery power, and visibility are the most critical factors you must consider. Fortunately, you can use a rotating laser level for both indoor and outdoor projects, just know that an outdoor laser level must provide more power and accuracy than the indoor option.
Speed of Rotary Laser Level
Speed is one of the factors you must not ignore when choosing a rotating laser level. The speed is measured in RPM. The laser levels with the lower Rotations per minute (RPM) are brighter and more visible. Thus, they can be more desirable for outdoor purposes where visibility in certain conditions is significant. Rotating laser levels with higher RPMs will travel farther, but their light intensity will be relatively lower. Hence, they can be more desirable for indoor measurements where visibility is not an issue.
Battery Power Of Rotating Laser Level
Since rotating laser levels tend to be brighter and project laser beams at longer ranges, they consume more power than regular laser levels. For this reason, you need to opt for a rotating laser measure which has a higher battery rating and can support your work for hours or days, even at one single recharge. You will surely need a laser level with higher battery power for outdoor activities, but average battery power will do just fine for indoor tasks.
Visibility Of Rotary Laser Level
The best rotating laser level 
is the one with the high visibility whether you use it outdoors or indoors. The outdoor rotary laser level is expected to maintain a high-intensity visible light. It would be best to go for a green laser level over the red laser option because the green color is more visible under any given condition. Keep in mind that a green laser level of the same caliber as a red one is costlier. Please make sure you are clear about the device's visibility before you settle for it.
Other Factors to Consider When Choosing a Rotary Laser Level
There are several considerations you need to make when choosing a rotary laser level, and one of such is the availability of accessories. Rotary laser levels work best with tripod stands and laser detectors, especially when leveling and aligning on irregular outdoor surfaces. The addition of protective eyewear and gloves can be great, but if they are not included in the package, you have to purchase them separately.
Besides, you need to pay attention to the debris and water-resistance feature of a rotating laser level, especially when you use it in unfavorable conditions. IP64 water resistance is one of the highest ratings you can find around.
Keep in mind that the warranty of the product is as important as every other factor; the longer the warranty coverage, the better the quality of the device. Furthermore, you can find the best rotary laser level
