Rotating laser levels project a continuous 360-degree arc of laser light to aid in marking building levels or aligning components. They are primarily used in commercial construction and offer high accuracy and flexibility, but are more expensive than static laser levels.
A rotating laser level is a device that indicates horizontal or vertical levels or other construction points using a continuous 360-degree arc of laser light. This continuous line of light is projected onto walls, floors or other structures to aid in marking building levels or to align several components mounted to a common height. The rotating laser level differs from conventional laser levels in that it projects the laser reference in a 360 degree arc. It can be used to project the reference line onto all walls or the floor and ceiling of a space at the same time instead of a single line plane.
The rotary laser level is primarily used in the commercial construction industry as it allows level references to be projected onto all interior surfaces simultaneously. This laser reference can be projected horizontally, vertically or at any pre-set angle. While the rotary laser level would also be useful in the do-it-yourself, or do-it-yourself field, the size and cost of the units prohibit general home use. The standard single reference laser level is much more appropriate for DIY use.
Another benefit of using a laser level is the fact that the reference line always stays above the work surface, thus making layering easier. Rotating laser levels offer the added benefit of the 360 degree arc of projection which can cover an entire indoor area from one point of projection. This makes tracking braces, panels, or any building element that runs around more than one wall in a room much easier than using any conventional level. This functionality extends to both spatial planes and adds considerable flexibility and very high levels of accuracy to construction measurement.
A rotating laser level should ideally be used from a laser level tripod, but any stable and fairly level surface will suffice. Most units are self-leveling, so installing them isn’t difficult. A typical device also incorporates warning features that notify the user if the unit shifts or drifts out of level during operation. The rotary laser level units are available in standard red diode models and new high visibility green light variants which are much more visible in bright light conditions.
The only real downside to the rotating laser level is the fact that the device tends to be much more expensive than static laser levels. Unfortunately, this makes the purchase difficult for the DIY enthusiast to justify. It can, however, be an indispensable piece of hardware in any construction crew’s arsenal, delivering results far superior to static laser levels and other conventional level reference methods.
