Rotary Lasers Vs. Line Laser Levels for Home Construction Purposes

Posted on July 4, 2018 by

Laser levels are extremely popular in the construction sector. Civil engineers, as well as construction specialists, use these devices on a day to day basis. Unlike the previous generation of levelling devices that had a small scope of human readability error, the modern laser devices are extremely accurate. You can use these devices for micron level accuracy while measuring the flatness or curvature of the surface.There are different kind of technique comes in the laser level machine you have to check best laser level machines at nearest store.

Two of the most common types of lasers include rotary lasers and line lasers. Here are some critical differences between them.

Operational Parameters

The basic operation of the rotary lasers and line lasers are same. However, while the line laser projects a line, the rotary laser projects a dot and utilizes that to measure the curvature of the surface.

  • Rotary Lasers: The rotary lasers project a rotating dot with a 360-degree They essentially utilize the best parts of both line and dot lasers. The rotary lasers use a detector device on the other end of the levelled field to detect the curvature.
  • Line Lasers: The line laser shoots vertical as well as horizontal lines and uses them for the measurement purpose. This device consists of multiple LEDs to shoot the laser lines out of the convex lens.


In terms of visibility, the rotary lasers are usually harder to see compared to the line lasers.

  • Rotary Lasers: These devices require a dedicated receiver unit at the other end of the field to detect the laser light.
  • Line Lasers: Unlike the rotary lasers, they do not require a detector device. The laser from this device is relatively very easy to see.


High-level construction requires the use of rotary lasers.

  • Rotary Lasers: If cost is not a determining factor, people should go for the rotary lasers over the line lasers simply because of the higher accuracy. The most popular rotary laser devices produce an accuracy that is nearly 100 times better than that of a line laser.
  • Line Lasers: The line lasers are more accurate compared to the dot laser, however, it is no match for a rotary laser.


  • Rotary Lasers: The rotary lasers are significantly costlier compared to the line lasers. The primary reason for the cost difference is the need for a dedicated receiver device.
  • Line Lasers: The line laser is the number one choice of construction specialists under tighter budget constraints.


  • Rotary Lasers: The rotary lasers have a good overall range. However, when it comes to pure visibility statistics, the line lasers win by a fair margin.
  • Line Lasers: The line lasers have an excellent vertical and horizontal range. However, it loses out on accuracy with increasing distance.

Ease of Use

  • Rotary Lasers: The rotary lasers are hard to use and require help from an expert.
  • Line Lasers: The liner lasers are relatively easy to use and set up.

If accuracy is your primary focus, you should go for a rotary laser device. However, if you want to save money and still get a fair amount of accuracy, the line lasers are perfect for you.
