A Complete Guide To Choosing A Rotary Laser Level

What is a Rotary Laser Level?

A rotary laser level projects a beam of light that rotates at high speed, enabling either a 360-degree horizontal or vertical plane of light. This laser plane provides an exceptionally accurate straight-line reference point for a great many construction and leveling requirements.

It is important to note that a rotary laser level does the work of giving a perfectly level guide over a long distance and across the whole work area. This line of laser light enables workers to align easily either by objects, surfaces, or elevations without the muss and fuss of having to level manually. With the permanent visible reference that rotary laser levels avail, leveling, aligning, and marking can be done effectively and precisely in either horizontal or vertical planes.

How Does a Rotary Laser Level Work?

A rotary laser level projects a laser beam rotating 360 degrees to provide a perfectly level horizontal or vertical plane. A diode within the unit creates this laser beam, which is sent through an optically precise rotating head. As this head spins, the laser beam forms a continuous plane of light to act as a reference for leveling.

For outdoor applications, the rotary laser level is used with a laser receiver or detector. The laser beam itself is not visible in bright sunlight over long distances, so the receiver is used to detect the beam. The receiver is mounted on a staff and has sensors that can pick up the rotating laser beam. It provides visual and audible indicators to guide the user in finding the exact level plane.

The laser receiver detects the position of the laser beam relative to its sensors. Most of them are usually equipped with LED lights or an LCD screen, showing if the receiver is above, below, or on the level plane. Most receivers also emit audible tones that increase in frequency or change in pattern as you move closer to or further from the level plane. A solid tone generally means that the receiver is perfectly level with the rotating plane of the laser.

Operating the receiver with the rotary laser level, a single operator can quickly and accurately determine and mark level points over long distances on a job site. This saves so much time and effort compared to using traditional methods of leveling such as a spirit level or transit level.

Horizontal and Vertical Leveling

Rotary laser levels usually have a self-leveling horizontal feature. Once on, the laser will self-settle on and project a true, level 360-degree horizontal line without any interference from the user. This saves time since it is highly accurate without the need for manual leveling of the unit.

Higher-end rotary laser level models often include a vertical leveling mode in addition to the horizontal mode. The vertical mode allows the laser to cast a plumb, vertical line in addition to the horizontal line. This vertical line can be invaluable for tasks like aligning framing, checking plumb on steel structures, or ensuring vertically-oriented construction elements are perfectly upright.

Most quality rotary lasers have an auto-stop mechanism designed that will prevent it from giving wrong readings if their position is inadvertently disturbed during use. In the event that the unit gets significantly knocked out of its self-leveled position, it automatically stops rotating and projecting the laser line instead of continuing to cast an out-of-level reference line. This helps avoid mistakes and reworks caused by an inaccurate laser line.

Applications of Rotary Laser Levels

Rotary laser levels are quite versatile pieces of equipment that can be put into use in various indoor and outdoor applications on different job sites. Their ability to project a precise, level reference line over long distances makes them invaluable tools for construction professionals.

Choosing the Right Rotary Laser Level

When it comes to choosing a rotary laser level, the following are some of the aspects on which to base your decision for getting the right tool:

Manual vs Auto-Leveling

The auto-leveling or self-leveling rotary lasers automatically set a perfectly level horizontal and/or vertical plane. These are perfect for larger jobs when high precision over a long distance is necessary. Manual leveling lasers require the user to do some calibration and could be best for smaller projects.

Green Beam vs Red Beam Visibility

Green beam rotary lasers are more visible to the human eye, especially over longer distances or in bright conditions. Red beam lasers are more budget-friendly but may require a laser detector for outdoor use.

Indoor vs Outdoor Use

For indoor applications like leveling floors, aligning cabinets, etc., a basic rotary laser may suffice. Outdoor jobs like grading, laying foundations, etc. require more robust lasers designed for all-weather use paired with laser detectors.

Accuracy and Range

Higher-end rotary lasers provide higher accuracy, such as 1/16" at 100 ft and a longer working range of up to 2000 ft diameter. Entry-level models give up some accuracy and range but can be perfect for small residential projects. Consider your typical job requirements when evaluating accuracy needs.

Buying vs. Hiring a Rotary Laser Level

One of the biggest decisions when it comes to using a rotary laser level is whether to buy one outright or hire/rent one as needed. Both options have their pros and cons:

Buying a Rotary Laser Level
Pros:

• Cost-effective in the long run if used frequently
• Always have it on hand when needed
• Can purchase accessories and become very familiar with operation
• Asset that can potentially be re-sold later

Cons:

Rotary Laser Levels vs Other Leveling Tools

Rotary laser levels hold an advantage over the convention tools of leveling, which are spirit levels and line lasers. The advantages include superior accuracy, with higher precisions, especially for long distances. Spirit levels do not have good accuracy, and as the distance is increased, usefulness is reduced correspondingly. The line lasers also don't achieve such a higher accuracy as attained by the rotary laser levels, which have the ability to provide perfectly level lines after hundreds of feet.

Another significant advantage of rotary laser levels is their ease of use and time-saving capabilities. Unlike spirit levels, which require constant adjustment and repositioning, rotary laser levels can be set up quickly and provide a continuous level reference line. This allows workers to work more efficiently, reducing the time and labor required for leveling tasks.

Rotary laser levels are also more versatile than other leveling tools. They are useful for both horizontal and vertical leveling, hence capable of handling various tasks such as concrete work, framing, drywall installation, and many more. Moreover, many rotary laser levels include additional features like slope adjustment and remote control.

More expensive than spirit levels and line lasers, rotary laser levels often come with advantages that outweigh the cost, especially for larger projects or professional contractors. The increased accuracy, efficiency, and versatility can result in significant time and cost savings over the long term, making them a valuable investment for many construction professionals.

In summary, rotary laser levels offer superior accuracy, ease of use, and versatility compared to traditional leveling tools like spirit levels and line lasers. While they come with a higher upfront cost, their benefits in terms of time and labor savings, as well as improved precision, can make them a cost-effective choice for many construction projects.
