Best Laser Levels for Construction




A guide to the best laser levels for construction


The laser level is an incredibly valuable control tool within the construction industry, providing access to unmatched levelling accuracy when dealing with vertical and horizontal alignment. A laser level is a tool that should not be underestimated, making it a must-have for every construction toolkit. When operating within the construction industry, laser levels are simply unavoidable and for good reason. They provide prime application across sewer installation, concreting, site grading plans, and other construction projects. 


Although the utility and importance of the laser level is not debated, selection processes go beyond application with a variety of styles being manufactured with varying features and functionality. So, when deciding which are the ‘best’ laser levels for construction, a broad range of factors must be taken into consideration. 


To better break down the fundamentals behind what makes a laser level the ‘best’ within the construction industry, a comprehensive guide has been provided outlining core design types, critical features, and brand recommendations. 


The top three laser level designs for construction 


The predecessors of modern laser level variations were often highly bulky and expensive tools with an expense that often didn’t justify utility across smaller construction sites and short-term projects. Today, laser level designs are highly practical with multiple design types to cater for a range of various applications. The top three laser level variants include:


 Plumb/dot laser level 

Plumb or dot laser levels produce single or multi-dot references across various work surfaces to assist operations in cases where marking is only required across one dimension. These laser levels act as the simplest way to make markings or calculations within the same plane it has been positioned and are commonly known as the best laser level for the money. 


Crossline laser level

Crossline laser levels, also referred to as just ‘line level lasers’, are more advanced than their compact counterparts, emitting a level line on a wall in either a straight-line or crosshair configuration. These lasers more notably perform best within an indoor setting, working irrespective of distance. 


Rotary laser level

Rotary laser levels emit a level line in a rotary fashion that utilises a projection unit that spins to throw laser beams at a 360-degree angle. Given the larger design of these lasers, surveying tripods are often required and may have to be levelled manually unless investing in a ‘self-levelling’ rotary laser. Though these lasers work well inside, they are significantly popular across outside construction projects and perform best across more complex projects. Outdoor use does, however, require the use of a laser level detector given the limitations of a human eye. 


Which features do the best laser levels need for construction?


What is considered the ‘best’ laser level for construction is highly respective to both system specification and project application. Where compact additions can be a highly versatile tool, larger construction applications look toward more capable positioning systems with a wealth of added features. These are the best features to be mindful of when considering which laser level is the optimal investment. 


Technical specifications 

Technical specifications can help define and differentiate laser level systems from each other and is something to be particularly mindful of. The best features which optimally serve the construction industry are accuracy measurements, self-levelling capability when applicable, and visibility ranges. Compact dot laser levels tend to have a range of 15-20ft with accuracy within 2-3mm at extended ranges. Larger systems such as rotary laser levels, however, will have a larger range of operation, spanning well over 150ft with accuracy variances at 4-5mm at extended range. 


Laser level design

Laser level design is another important feature which is often underrated across construction sites. Additions such as mounting devices and self-levelling features can be critical when considering which laser level suits individual applications best. Self-levelling systems can prove to be a valuable asset across outdoor construction initiatives with most systems levelling horizontally within 30-40 arc seconds.

Miscellaneous specifications

Miscellaneous specifications refer to elements such as battery life which can greatly affect the overall utility of a laser level across long-term application. Depending on which battery configuration is used, you can expect high-end laser levels to remain functional for upwards of 20 hours. 


The best laser levels for construction


In terms of which is the best overall laser level for construction, there is no blanket answer with categorical factors and applicational elements playing a large part in the selection process. The answer will always be highly individualised, however, there are few notable laser levels which hold leading specifications and are likely to outperform other variants throughout most applications.


The best compact laser level - When dealing with digital laser sensors that are compact, yet highly versatile - many begin to trade-off performance in favour of more features. The aLine ML5G is one of the latest compact designs which have been built with no compromise, making horizontal and vertical alignment faster and easier. This model features vertical and horizontal beams that can be used simultaneously to create a crossline, as well as a dot beam. 


The best rotary laser level - Rotary laser levels are often the most sought after, with immense capability across a range of various applications. The aLine AL-HVG is part of the next-generation of self-levelling rotating lasers, featuring a long-range high accuracy laser that stands up to the elements with all-weather dependability and a battery life of up to 100 hours. This model also features an operational range of 800m with an integrated smart long-range receiver in tandem with horizontal accuracy within 10 arc seconds and a self-levelling range within 5 degrees. 


The best laser level kit - If looking to invest in a kit, it is vital that all components are of quality and built for a versatile range of construction applications. The aLine AL-HVR rotating self-leveling laser kit features electronic self-levelling applications that can project beams with an accuracy within 3mm. The laser also features an operational range of 500m, dual slope operation, and alternative spinning functions that are complemented with
