How to Search for the Perfect Rotary Laser Level?

Now that you have knowledge on the top of the line levels, the next step is to shop for your own. How do you select the best rotary laser level? Below are the factors you should consider:

  • Indoor Use: Multiple line lasers are ideal for aligning structures and storage units in an enclosed space.
  • Outdoor Use: A rotary laser level must have a secure tripod to accommodate uneven terrains and surface as well as long distances. Colored Goggles are essential to view the beam projected by the level more easily.
  • Take into account the size of the space (for indoors) and the distance that the beam will travel (for outdoors). Bright and visible beams are attained with low RPM (rotations per minute) laser levels but cannot accommodate long distances. Faint beams are provided by high RPM laser levels, which are suitable for long distances.
  • Consider the stability of the working space. Indoor projects will work fine with the manual laser level. Self-leveling laser levels are best for outdoor use on uneven surfaces.
  • A level surface is best for rotary laser level. Available surfaces may be used such as buckets, but a tripod is advisable.

Steps in Choosing the Right Rotary Laser Level

Assess Your Needs

Do you need it for professional use or general utility? Note that rotary levels can cost quite some amount of money, which is why sometimes, it is not best for DIYers. But if you evaluate your needs and decide that this tool will have high utility for your home projects, then you may proceed with the purchase. You also have to consider if you will need the level for indoor or outdoor use as well as how much space you will be working on. Your needs will dictate the type of level suitable as an investment.

Decide On The Features

Rotary levels can cost from $15 to $1600. The pricier it gets, the more features it has. Decide on what features are necessary for the level. Your job and setting will need different features. Indoor and outdoor environments call for different sets of qualities as well. Here are the essential features of rotary levels:

  • Minimum range of 20 feet for reliable accuracy – The farther the distance you will be using the level on, the greater range and accuracy you need.
  • Self-leveling mechanism – If you want no hassle in leveling properly, it must have this feature. Some levels only self-level in a horizontal mode then requires manual leveling in a vertical plane. Some levels, the pricier ones, have self-leveling features for both the horizontal and vertical modes.
  • Automatic Out of Level Indicator – This may come as a blinking light. It is a useful feature to indicate the need for level adjustments.
  • Backup Power – Not all laser levels have a backup battery. If you will be working long hours, a backup battery is essential to lessen disturbance in the task.
  • Protective cages and padding – The level head must have protective cages if you will be using it outdoors under different weather conditions. The padding on the transport case is necessary to ensure the safety of the tool despite bumps when being transported and carried.

Choose the Right Speed Options

Rotary laser levels have variable speed modes, which differ in the minimum and maximum speed. Determine the light conditions and the size of the setting of your leveling task. Knowing this will allow you to decide on the slowest and highest speed options you need for accurate leveling. The faster the RPM or speed, the better range you have. The slower the speed, the better visibility you can work with.

You also have the choice of fixed rotation speed. This is commonly used in construction application where only one speed is needed in broad daylight, and that is fast. Since it has a high speed, the laser beam will be less visible, which means that a laser detector receiver is needed to locate the line. A minimum of RPM is required for fixed rotation speed levels.

Consider Your Budget

As mentioned earlier, rotary levels can range from $15 to $1600. Commonly, these tools are priced around $400. You have to compare your needs with the budget that you can handle. Short-term savings for a cheaper model for the level is not always the best option.

You are yet to find out that it is not stable and that it does not provide enough protection when you use it outdoors. You have to determine how much you can afford to allocate for the purchase of the level for the best quality possible.


Rotary laser levels have a broad application from construction to landscaping to home projects. Its importance extends to the leveling and aligning of commercial and residential structures whether within the interior or on the exterior of property. Their function is essential in ensuring the quality of installation and trimming while contributing to the longevity of structures and units because they have been properly leveled and aligned.

With the broad range of applications of laser levels, it has become a necessary investment for tradesmen, service providers, DIYers, and of course, homemakers. The vast selection of models in the market will entail a lot of evaluation for the buyer. And with the right choice, a consumer will benefit from the versatility, durability, and accuracy of the tool.
