Best Rotary Laser Levels: Reviews & Buying Guide

A laser level is a controlling tool that is mainly used at construction or engineering sites to control the laser beams. It can be fixed to a tripod. The laser beam is arranged or leveled according to the accuracy of the device and it gives a fixed red or green beam along the horizontal or vertical axis. It can be categorized into three types:

  • Plumb Lasers
  • Laser Line
  • Rotary Lasers

  • Plumb Lasers

Plumb lasers give a dot on the screen as a point of reference. These are the simplest and cheapest laser that are available, but it has the least power to keep the laser beam.

  • Line level Lasers

Line level lasers are also known as Laser line generators which give a beam in the form of a level line to a wall or work area. They are designed to cover the wide range of angle which may range from 160 degrees along a vertical line and about 130 degrees for a horizontal line.

Line level laser can produce lasers both dual beams and also split beam which emits vertical and horizontal lines to give plumb and also level. Best use of these models are indoors or mainly for short coverage area. The usage of this laser is possible outside, but it will be difficult to detect the laser in daylight.

How to use it best ?

  • When the work-space is indoors, the Bosch GRL300HVCK Rotary Lasers are used for interior works like drop ceiling installation, trim work and chair rails etc. For these, lasers generally include a wall or ceiling-mount bracket and remote controls.
  • Also, there is no need for laser detectors in the indoors since detectors are generally used for outdoor or exterior work and not indoors whereas some products do include a laser detector with their Interior Lasers as per the convenience of the customer.
  • In case, there is a need to use these laser levels outdoors, it can even be used outdoors but make sure there is always a detector required while working outdoors since the human eye cannot see the laser beam in bright daylight.
  • Other than the interior work, these Laser Rotary Levels are good when working outdoors for exterior work such as grading & utility work is underground, site maintenance, construction of the stakeout settings, etc. In these cases, an exterior laser Rotary Kit should include a Grade Rod and a Laser Detector.
  • Laser Detectors are required if working outdoors because most of the laser beams are not bright enough to be seen by the naked eye. Also, the uses of a laser detector will almost double the range of a rotary laser. In some products, the Detectors are provided along with the kit whereas in some cases it has to be purchased separately.
  • If a laser kit does not include a laser detector, then make sure to buy a red-beam detector for red-beam laser levels and green-beam detector for green-beam laser levels as they are the best detectors available in the market and give a good result.

How to Use a Rotary Laser Level ?

  • Make sure that the rotary laser level is set on a tripod or flat surface. A stable object can be substituted, something like sawhorse or bucket.
  • Set it up to the desired height.
  • Now turn on the laser on the laser level.
  • Wait a moment so that the laser level can self-level by itself. If a manual rotary laser level is used, then make sure that it is calibrated correctly.
  • If you are indoors, its ready to marks as necessary for your project whereas if outdoors, continue to step 6.
  • Turn on the laser receiver. Check whether the receiver is working properly or not
  • Move the detector along a grade rod to the desired location, it has to be done till a beeping is heard, which means the detector has found the laser.
  • Based on your initial height marked, calculate changes in elevation elsewhere in the workspace.


The uses of Rotary Laser Level

  • It is easy to explain with an example to understand how a Rotary Laser Level can be used in case you have fit or install a chair rail around a room. The toughest part is to make sure that the chair rail is in level and also in the same height from the floor on all the four sides of the room.
  • Without a Rotary Laser Level, user may have to take lots of measurements and make markings on walls as well as on floor. Other than that it has to make sure of the tape measure and traditional bubble level. With a Rotary Laser Level, every other thing can be replaced by just placing it in the center of room on a tripod to hold or level it.
  • Other applications of Rotary Laser Level are like installation of kitchen cabinets with multiple counter-tops, leveling floor, drop-ceilings, etc.
  • In some cases the Rotary Laser Level would be turned on and instead of shooting a beam of light around the walls of the room, the beam will be rotating 360-degrees across.
  • There is a lot difference when it comes to working outside Rotary Laser Level. As it is exposed to sunlight, the human eye cannot see the laser beam of light.
  • Here also let’s take an example for simple outdoor application of a Rotary Laser Level first. Instead of a chair rail around a room, consider it as installation of deck in backyard. The Rotary Laser Level can be set up on a tripod, and also a Detector can be used to detect or to establish the height of the deck’s floor. Once completed, the tripod can be moved so that it can be used with a Detector to build a level wall or rail around the deck.
  • Other outdoor applications for Rotary Levels may include some works like rough and fine grading, where a grade rod is used; or rough and fine excavating, again using a grade rod to keep a record how deep it has to be dug out, alignment of concrete forms, and setting up drainage where a slope feature of the Rotary Laser Level would be needed.


A laser level is mainly used in construction sites or engineering sites to control the laser beams. After setting the Laser level, the user can do different type of works that range from grading, concrete pouring, installing fences, chair rails installation, foundations laying out for construction sites, and more can be done from site. Some of the laser levels as said above are mainly for the indoors only, whereas some can handle both indoor and outdoor.

First, Rotary Levels have a different or variable speed control. At slower speeds, the beam of light is more clearly seen, whereas at higher speeds, there is more effect, that is only a single line will only be seen through to the room.

Second, Rotary Laser Levels have a different scan mode which allows changing the 360-degree rotation to a 30-degree or 60-degree area. By just narrowing the angle of the laser, the laser beam becomes more concentrated and more visible to the human eye. If the work is outside or whether the user is working both outside and inside, the color of the beam, red or green, does not matter.
