Big project in the works? Forget plumb lines and spirit levels: what you need is a laser level! From basic spot levels to rotary or cross line models, you're sure to find a laser level to suit your needs. Read on to find the right laser level for your job.

Different types of laser level
There are several types of laser level designed to tackle different tasks. In order to make the right choice, it's best to start by determining your needs.
Spot laser level
Designed for indoor use, spot laser levels are the most basic models available. They project a dot or multiple dots to mark out levels or 90-degree angles with precision.
The projectionrange of these models varies from 5 to 20 metres, depending on the model, and they can be accurate to 0.5 to 0.8 mm per metre. They are ideal for tasks such as building a stud wall.
Line laser level
Perfect for installing skirting boards or ledges, these models work just like a spot laser level and are also designed for interior use; in fact, the only difference is that they project a visible line instead of a dot.
Their projectiondistance ranges from 5 to 20 metres, depending on the model, and they offer a similar level of precision.
Cross line laser level
Like the aforementioned models, cross line levels are generally used indoors for tasks like laying tiles or securing furniture.
They project two lines that produce a precise 90° angle, and offer the same projection range and accuracy as the above models.
Rotary laser level
Often used by professionals, these models are ideal for earthworks, levelling and masonry work. The most advanced type of laser level, they are also the mostefficient. Suitable for outdoor use or in very large indoor spaces, rotary laser levels use a diode to project a beam of light up to 360°, depending on the model. The projection range can be up to 50 metres and are accurate to 0.25 mm/m.
All types of laser level can offer a self-levelling function whereby the device automatically levels itself no matter the type of surface it is placed on. Now that's progress!
The advantages of using a laser level
No matter the size of your project, nothing is more important than good alignment. As the size of your task increases, so will the surface area in terms of both length and height and you may discover pretty quickly that a basic spirit level will struggle to keep up. But luckily for us, the 21st century has provided a practical, easy to use, and accessible tool in the form of the laser level.
Some models offer a projection range of over 50 metres with exceptional precision, making a laser level essential for any largescale project undertaken indoors or outdoors.
Laser level accessories: the essentials
Telescopic levelling staff
A telescopic levelling staff can be used to help you take measurements when working over a large distances (4 metres minimum).
Laser vision goggles
Intended mainly for outdoor use, these glasses will help you to see laser beams.
Tripods and wall mounts
It goes without saying that you will need a tripod; you can even find models equipped with rotating bases.
A wall mount is a handy accessory that helps you measure at greater heights.
Assessing the accuracy of a laser level
The precision of your laser level is linked to the size of the beam per metre.
Look for models that are accurate to 0.2 or 0.5 mm/m. The lower the measurement, the greater the usable distance of the laser beam and the more accurate it will be.

Electrician by trade, I first worked in industrial estates where I installed, wired and fixed a large number of electrical installations. After this, I managed a team of electricians for this type of work. 10 years or so ago, I turned to building and construction. From the modest family home, to gyms and theatres; I have been able to coordinate, audit and organise all sorts of construction sites. for 4 years now, I am restaoring and bulding an extrension to a bungalow in the heart of the welsh countyside. My experience in manual work and my knowledge means I am proud to be of service. Terraces, interior design, roofing, plumbing, electricty, anything goes! We have, my wife, daughter and I, built almost everything we have from scratch! So to answer all of your questions, and to orientate and advise you on coosing your tools? Easy!
